An easy, one-bowl, Asian-inspired dessert: Black Sesame Mochi Cake! All the nutty deliciousness of black sesame seeds. Plus, the squishy, chewy fun of mochi!
Lately, I’ve been obsessed with black sesame seeds. This nutty, savory little seed makes everything taste better.
In my quest to find the perfect black sesame dessert, a friend told me about mochi cake. Squishy, chewy mochi transformed into cake-like form? I had to give it a try.
Why Black Sesame Mochi Cake?
Mochi cake is an Asian-fusion dessert with Hawaiian roots. Glutinous rice flour (instead of regular flour) makes the cake batter chewy, bouncy, and squishy — like mochi. The perfect, gluten-free snack cake!
Using Hawaiian Butter Mochi as a base, I tinkered and toyed until I made a Black Sesame Mochi Cake recipe that I loved. And couldn’t stop baking and eating!
Adding black sesame powder added instant richness, depth, and savory oomph. Plus, the dark, moody color!
Take one bite and you’ll agree — Black Sesame Seed Mochi Cake is a gluten-free dessert that is so satisfying to eat. Bouncy and springy. Sophisticated yet so easy to put together. A party in a 9×13″ pan! And not-too-sweet!
Ingredients:
- Canned Milk. Mochi cake is classically made with two kinds of canned milk: Coconut Milk and Evaporated Milk. When you live on a tiny, volcanic island far from land-grazing cattle (i.e., Hawaii), canned milk is easier-to-find and cheaper than fresh milk. Canned milk lasts forever. And requires no refrigeration. All to say — you could make mochi cake with regular milk. But I’ve decided to stay true to the Asian-fusion, Hawaiian origins of this cake by using canned milk.
- Black Sesame Seeds/Powder. Earthy, nutty, and savory. Buy black sesame seeds and toast and grind them yourself. But if you want to skip a step, buy a bag of powdered black sesame seeds instead! So much easier! The taste difference is minimal.
- Glutinous (Sweet) Rice Flour. Regular rice flour is not the same. Popular brands: Mochiko Blue Star Sweet Rice Flour by Koda Farms and Thai Erawan Glutinous Rice Flour. Also called Sticky Rice Flour and Sweet Rice Flour. It will give mochi cake that characteristically chewy, bouncy texture.
- Coconut Oil. Coconut oil is more fragrant than vegetable oil, if you have it. But in a pinch, any kind of neutral oil works — grapeseed, vegetable, or canola.
- Coconut Extract. Although optional, it adds more coconut aroma and flavor.
- Sugar. Balances the flavor of the black sesame seeds. Just enough to make it “not-too-sweet”!
- Eggs + Baking powder. For structure and rise. It is a cake, after all!
Instructions:
- Toast black sesame seeds. Toss a few times in a non-stick skillet until they crackle and slightly smoke.
- Grind black sesame seeds in a food processor to a powder.
- Whisk batter together: black sesame powder, sugar, melted coconut oil, coconut extract (if using), eggs, coconut milk, evaporated milk, glutinous sweet rice flour, baking powder, and salt. Whisk well.
- Pour into a well-oiled 9×13″ pan.
- In a small bowl, combine 1 Tbsp black sesame seeds + 1 Tbsp white sesame seeds.
- Sprinkle sesame seeds along the edge of the pan.
- Slide carefully into the oven and bake until done. Cool for 1 hour and cut with a serrated knife. Enjoy!

PRO Tips:
- Toast sesame seeds. Don’t skip this step! For extra nutty and flavorful sesame seeds.
- Grind sesame seeds well. Pulse until the oil starts to release and it looks sticky; the powder will look moist. Look for a powder-like texture that clumps and sticks together. Exercise caution — if you pulse too much, it will become tahini paste!
- Oil the 9×13″ pan. Use a pastry brush or paper towel dipped in oil to generously grease the pan. For easier removal.
- Cool for 1 hour (minimum). When hot, the cake is very sticky and hard to slice.
- Use a serrated knife. Makes for easier slicing than a regular knife.
FAQs:
Can I halve this recipe?
Yes, I’ve successfully halved this recipe in an 8×8 pan! I recommend using 1 can of coconut milk total versus 1/2 can coconut milk + 1/2 can evaporated milk for ease and convenience. The cook time is about 45 minutes.
Does Black Sesame Mochi Cake freeze well?
Yes, mochi cake freezes very well. Cut into squares before freezing to defrost by individual portions. Cool completely and store in an airtight ziploc bag. To defrost, lightly reheat in a toaster oven/Air Fryer/oven, about 5 minutes at 350F.
Can I substitute the evaporated milk with a plant-based milk?
Yes, the canned evaporated milk can be subbed with almond milk, oat milk, soy milk, coconut milk, and regular milk. This recipe is very forgiving and any kind of milk should work! I like to use evaporated milk for ease and convenience, and also — to celebrate its Hawaiian origins.
Why is my mochi cake not as dark as yours?
To ensure a rich, dark color — weigh your ingredients. Three cups of glutinous rice flour can weigh anything from 300-450g, depending on the way it’s packed in the measuring cup.
I’ve baked this cake many times by using BOTH black sesame powder from the store AND by grinding my own seeds at home. Each time, the interior comes out dark and rich in color. However, glutinous rice flour has a very different texture than regular flour so it has a tendency to pack down and become dense.
How do I determine doneness?
Determining doneness can be challenging. The skewer test will not work, as the batter will remain moist and sticky even when fully baked. Instead, check for doneness by looking for edges that are brown and naturally pull away from the pan. Give the pan a little shake — the center of the cake should be set with no jiggle.
How can glutinous rice flour be gluten-free?
Glutinous refers to the fact that it’s made from sticky glutinous rice — not gluten — so it’s actually gluten-free.

Easy Black Sesame Mochi Cake
Equipment
- 9×13 pan
- Large Bowl
- whisk
Ingredients
- 1 cup/120g black sesame seeds (or 3/4 cup black sesame powder, if you want to skip roasting and grinding the seeds)
- 1/4 cup coconut oil (melted) (regular vegetable oil also works)
- 1 tsp coconut extract (optional – for extra coconut flavor + fragrance)
- 1 1/2 cups/300g sugar
- 4 eggs
- 1 400ml/13.5 oz can coconut milk (full fat, not the boxed kind)
- 1 354ml/12 oz can evaporated milk
- 3 cups/300g glutinous (sweet) rice flour
- 2 tsp baking powder *(use 1 1/2 tsp instead of 2 for a more gooey cake)
- 1/2 tsp salt
Garnish (optional)
- 1 Tbsp black sesame seeds
- 1 Tbsp white sesame seeds
Instructions
- Preheat oven. Heat oven to 350F/175C. Generously brush a 9×13 baking pan with melted coconut oil on the bottom and sides. Set aside.
- Toast black sesame seeds. (Skip this step if using black sesame powder). Add black sesame seeds to a dry skillet over medium heat. Toss the seeds from time to time or mix with a wooden spoon, until they begin to crackle and smoke, about 3-5 minutes.
- Grind black sesame seeds. (Skip this step if using black sesame powder). Transfer seeds to a food processor. Pulse until seeds are finely processed into powder, about 1-2 minutes. Be careful here — there is a fine line between powder and paste. Pulse the seeds until the oil starts to release and the seeds clump together just a bit; the powder will look moist. But exercise caution — if you pulse too much, you will end up with tahini paste!
- Whisk batter together. Scrape sesame seed powder into a large bowl. Add sugar, melted coconut oil, and eggs. Whisk well until smooth, about 1-2 minutes.
- Add evaporated milk and coconut milk. Whisk well, making sure the batter is smooth and lump-free, about 1-2 minutes.
- Add glutinous sweet rice flour, baking powder, and salt. Whisk well, sure the batter is smooth and lump-free, about 2-3 minutes.
- Pour into 9×13 pan. Scrape the batter into the well-oiled pan. It will be very loose and runny.
- Garnish. In a small bowl, combine remaining 1 Tbsp black sesame seeds and 1 Tbsp white sesame seeds. Sprinkle along the edge of the pan. (If you prefer, double the amount of both sesame seeds and sprinkle completely over the entire top, not just on the edges.)
- Bake. Slide carefully into oven and bake until done, about 50-60 minutes. Checking for doneness will be challenging, as the batter will remain moist and sticky even when fully baked. Instead, check for doneness by looking for brown edges that naturally pull away from the pan. Give the pan a little shake — the center of the cake should be set with no jiggle.
- Cool and serve. Transfer to the counter. Cool for 1 hour (at least) at room temperature. Cut with a serrated knife into 24 squares.
Hi! I’m so excited to try this recipe. Was wondering, can you use butter instead of coconut oil?
Yes, you can definitely use melted butter instead of coconut oil. Any kind of cooking oil works, too. Enjoy!
absolutely delicious, thanks!
Thank you for this recipe it is so delicious! I followed the weights in the recipe the first time and it was good but a little softer than I expected in the center. But then I made it again and noticed that youโre recipe says that 3 C of glutinous rice flour is 300g, and my bag of Bobโs red mill said that 3 C was actually 480g so I changed it for the second batch. Itโs in the oven now and Iโm hoping that makes the difference! Thanks again!
I made this today. Was so easy and so good ๐. I saw it can be frozen, but can it be stored room temperature or refrigerated instead? And if so how long?
Hi! Yes, it can be stored at room temperature for 2-3 days and/or refrigerated for 4-5 days. For anything longer than that, I would recommend freezing.
hi! i came across this recipe and super excited to try it! just wanted to ask, if we don’t have coconut or vegetable oil would canola work?
Hi! Yes, canola oil will also work! Thank you
My cake turned out soft inside instead of googy/chewy. The edges and top were good. How do I make it like a mochi cake, ie googy inside?
Make sure to use glutinous rice flour instead of regular rice flour! It’s also called Sweet Rice flour, Sticky Rice flour, or Mochiko flour. I use Thai Erawan Elephant brand. If that still doesn’t produce a gooey and chewy texture. use a scale to measure the ingredients. Good luck!
Thank you! This recipe is exactly what Iโve been looking for! It was sooo delicious! Crunchy golden edges & perfect sweetness level. I baked it in 2 separate pans to get more edge pieces! This is my new fave dessert!
Hi Lis! I made this today and it is wonderful! I am wondering if it is supposed to be gooey on the inside? I was trying to re-create one I had at a nearby cafe and the flavor was spot-on, but the whole cake at the cafe was the consistency of the top and sides (of the pieces along the outer edge of the pan). The inside of this one was gooey instead. I noticed that it puffed up nicely in the oven and when I pulled it out, but an hour later, it had sunk down. Could that be the problem? If so, any ideas on how to keep that from happening? Maybe when I jiggled it to test for doneness?
Hello Zak, thanks for your question. If you don’t want it gooey — add 2 tsp baking powder instead of 1 1/2 tsp instead. I like a little ooze but everyone is different! The cake always puffs and deflates in the oven. It will harden as it cools. Hope this helps.
12/10!!! I was curious how the sesame seeds would grind in a food processor, but it worked out really well. Such a simple recipe for such a dynamic outcome. Love how the edges are slightly crispy, the subtle sweetness + sesame flavor and the softness of the mochi. Wow. I had no idea what to expect and this really blew my mind. Might be a new go-to potluck dessert from now on. Thank you so much for sharing!
Really want to try this amazing recipe! What is the difference with packet coconut milk and tinned coconut milk. We usually use the packet version UHT here in Singapore and its difficult to find the tin version.
The packet coconut milk in Singapore might be the same as tinned coconut milk here in North America. If there’s no other option, give it a try! The packet coconut milk here in Canada is very thin (for drinking) and watery.
This was so tasty! I was wondering if you had any suggestions on how to convert this to a matcha recipe? Thanks!
Delicious, easy. Not too sweet! Highly recommend
Hello, this recipe looks really delicious, however I am curious if there is a way to make this without any coconut? Thereโs an allergy in my family and while I could probably make with alternatives, Iโm not sure how everything will holdup as this seems to be made with quite a lot of coconut.
Yes, you can make this without coconut. Simply leave out the coconut extract and coconut milk. To compensate, double the evaporated milk. It’s a very forgiving recipe.
Please let me know how you came up with this recipe? Is it inspired by an already existing or is it totally your creation?
It’s inspired by Hawaiian Butter Mochi cake. The link is in the main body of the blog post!
What quantity of sesame paste do you end up with when you grind your sesame?
I don’t re-measure. If there’s a difference, it’s probably minimal. The cake is very easy and forgiving so slightly different amounts won’t make a big difference.
Hi, Can I use black sesame paste instead of sesame powder and in what quantity, maybe someone knows? Thanks
I have not used black sesame paste in this recipe but if you wanted to try it, using the same amount as black sesame powder may be a good start. In a regular cake, the paste would affect the texture but this cake is already very gooey and mochi-like in the middle so I don’t think it would affect it as much. Good luck!
I would like to make this only for 2 people in 2 individual porcelain ramekins, do you think it’s possible? If so, what would you cut the recipe down to and for how long would you bake? Thank you so much this looks delicious ๐
I’m not sure of your ramekin size so it’s difficult for me to give you a recipe and baking time. My suggestion is to halve the recipe and bake in a square 8×8 tin. You’ll get 9 generous, large-sized squares that will be plenty for 2 people, with leftovers. If you can’t eat everything, wrap tightly in plastic film and freeze. The mochi cake defrosts/reheats very well.
Hello! How should I adjust the bake time if I bake in a 8 x 8 tin?
Thank you!
Surprisingly, the bake time is the same — about 50-60 minutes! Enjoy!

Tried this recipe today it’s delicious! Even hubby who doesn’t like sweets loved it! For some reason mine wasn’t as dark as yours though but I followed your recipe to a T
Hi Tammy, Thank you so much for your feedback! Did you grind the seeds yourself or did you use ground black sesame powder? If you grind the seeds, you have to grind more than you think. The seeds should start releasing their oils and stick together, just a little bit. The only time it doesn’t come out as dark is when I don’t grind the seeds long enough. Hope this helps!
Love this recipe! I make this all the time and my family loves it!! Just making sure that if I๏ฟฝm using store bought roasted seasame seeds, I just need to put it straight into the blender right? Thank you so much!
If you roast the sesame seeds first, there will be more aroma and nuttiness. But in a pinch, I’ve used regular sesame seeds and it’s come out fine, too. So glad you love it!! xx
This looks so good! Iโm planning on making it this weekend but wanted to know if one 1lb box of Mochiko rice flour would be enough for the 3 cups called for in this recipe.
Yes that should be perfect!
Hi, I have been reading your recipe over and over again. I have most of the answers from all the comments but the coconut milk. May I know the fresh grind coconut milk from the market works better or boxed one?
Hi. Thanks so much for your feedback. I just included the most frequently asked questions in one section, FAQs, to make it easier for people to get their answers. Iโve never used fresh ground coconut milk (sounds divine!) but have only used canned coconut milk, not boxed. The recipe is very forgiving so I think either would work but I am not 100% sure as Iโve never baked it that way. Let me know how it turns out!
If I halved the recipe for a 9″x9″ pan, do you think the cake would come out too thin?
Iโve halved the recipe in a 8×8 with great success but havenโt tried a 9×9 pan. I donโt think it would be too thin but I would watch that it doesnโt get over cooked. Look for corners and sides that shrink away from the pan with crusty edges- that tells you itโs done!
I’ve been craving black sesame seeds recently and decided to give this recipe a try. I’ve never had a mochi cake before but I really liked it. It was spongy, moist, and not overly sweet. While it was delicious, mine didn’t look much like the pictures. Rather than being pitch black, mine looked light grey and yellow at the same time. I followed the recipe, but did i not add enough black sesame? I was a bit confused about measuring the sesame seeds. I measured 3/4C of whole sesame seeds but when i ground them, the resulting powder was more than 3/4C. I added all of it but should I not have?
This has happened to me as well. The sesame seeds need to be ground down enough until the oil releases and it starts to clump together a bit. Itโs a fine line between ground powder and paste so you have to be careful but at the same time โ it needs to be ground down enough to be powdery! If you can find it, look for black sesame powder at the store and that will guarantee the texture of the seeds. Good luck!
This sounds great can it be made with almond or rice milk instead of regular or evaporated milk? We have family with regular milk allergies
I๏ฟฝve never tried it with either but it should work! This recipe is very forgiving. Let me know if you do!
So delicious. Made it with black sesame seed powder. Also I made a few adjustments, used only 1 c sugar and substituted almond milk instead of evaporated milk. Still so good. Although mine didn๏ฟฝt turn out as dark as this picture here. Next time I๏ฟฝll try grinding my own powder.
I used a nonstick pan slightly bigger than 9×13. Mines did not quite come out like the picture, but very good and tasty. I did not grind the sesame good enough, next I will. Everybody loved it! Thank you for sharing??
Hello, i have black sesame paste and i would like to make the cake using it, what do you suggest? Thanks
I๏ฟฝve never made it using black sesame paste but I๏ฟฝm guessing it would be similar? If it๏ฟฝs sweet, you may need to adjust the sugar ratio. Try subbing 1/4 cup black sesame paste for the seeds and follow the rest of the recipe exactly. Then taste it and add more paste if it needs more black sesame flavor. Let me know how it goes!
Hi! Can you let me know how many days this mochi cake will last? Thx.
It๏ฟฝs never lasted longer than 3-4 days in my house lol. But I๏ฟฝm guessing about 5 days max? Any longer than that and I would freeze it. Mochi keeps very well in the freezer. Just defrost individually pieces at room temperature. Or, I think a toaster oven or microwave could also work!
I’ve used this recipe a few times and it’s turned out great! The black sesame is pronounced. My friend has told me she loves sticking the pieces in an air fryer after the first day to get the crunchy bits on the outside.
Hi! Is there a substitute for evaporated milk? Thx.
I think you could use regular milk but I’ve never tried it myself. For a 12 oz can, that would be about 1 1/2 cups. Let me know how it turns out if you do!
1st time baking this black sesame Mochi cake using sesame powder. I doubled the amount of black sesame powder. So easy & delicious ๐ highly recommended.
How do you store it after it’s cooled? It’s delicious!
Thank you! I loosely cover and store at room temperature. Hope that helps!
Question when you bake this, do you cover it with foil? or bake it open?
I bake it open!
I loved this recipe and have made it several times already! I’m curious: do you have any advice as how to make a version of this recipe with matcha instead of black sesame?
Iโm so glad to hear that you love it!! Matcha sounds like a great idea. I should put in on my list for recipe development. Since I donโt know how it will affect all the other ingredients, Iโm not sure what to recommend. But Iโll let you know if I come out with something successful. Thanks again!
would it be do-able to make mini cupcake size mochi cakes using mini cupcake pan using the same recipe? how would you adjust the baking time or temperature? thank you
Iโm sure that could work but Iโd definitely adjust the cooking time. Check at 25 minutes and let me know how it goes! The skewer test is not great for this recipe, instead check for a firm top that doesnโt jiggle in the middle when you shake the pan gently โ also, the sides should pull away from the pan. Good luck!!
Oops realized you said mini cupcake – maybe check around 12 minutes then?
how thin is the batter?
It’s like regular cake batter. See the photos above!
I tried this today for my fiance’s birthday and it came out exactly as it looks in your photos! I’m terrible at baking and this is the first thing I’ve successfully made!! I also halved the recipe and used a 8×8 pan like another commenter. Thank you!
Yay! So happy to hear that it was a success!!
Can you taste the coconut (or smell) as well since you used coconut milk? I’m kind of afraid to try because I dont like coconut scented desserts (but I love black sesame). Is there any alternative to coconut milk? Also, if I decide to follow the recipe as it is, do I use sweetened coconut milk or evaporated milk or both unsweetened?
If you donโt like coconut, try using two cans of evaporated milk instead. The coconut flavor/scent is not strong but still there. Also you can sub the coconut oil with vegetable oil. The evaporated milk I use is unsweetened. Good luck!
Followed the recipe exactly and it came out incredible! Made it for a Chinese family for Lunar New Year. They loved it. Gone in a day and none left to freeze. Thanks <3

Delicious! I halved this recipe and used an 8×8 pan. It still took an hour to cook but it turned out great! Very easy to prep, especially since I used pre-ground black sesame. They turned out soft, chewy but not sticky, and not too sweet!
Sounds perfect! Thank you!!
have you tried this recipe using butter instead of coconut oil?
No I havenโt! Let me know how it turns out if you do.
Looks delicious! How did you get the cake out of the pan? Did you use parchment paper to lift it out without it sticking?
I brushed some melted coconut oil all over the bottom. But you could use any kind of neutral oil to grease it well. I didnโt use parchment paper and they lifted out easily!
If I use sesame powder how much would be needed for the recipe?
The same amount should be fine. Thanks for your question and Iโll clarify the recipe!
Should the cake cool down in the pan for an hour or remove it to cool on rack? Is in the oven right now.
I let it cool in the pan ๐
