Author Notes

If you were to cut yourself a slice of the deep chocolate, shatter-topped, brownie-like cake pictured above, how big would you make your piece? Most of us would be fairly conservative, if not in an act of modesty than in one of prudence–no one likes to be caught halfway in the middle of a sea of too-rich cake without a life preserver.

But what you don't know about this cake is that as dense and rich and indulgent as it looks–as much as it could pass for a nearly-flourless chocolate cake–it is none of those things.

I'd like to make a case for why this mochi cake–more squishy than gooey, more subtle than sweet–is better. And it starts with the fact that, with its surprising spring and spryness, it is inhalable.

See, on the chart of Words Often Used to Describe Cake, "squishy"–the most apt description for mochi cake–is overlooked ("soggy" appears twice because it is particularly offensive). We talk about light cake–the angel food "cake" you'll eat and eat and feel nothing at all, making you question your humanness. We talk about dense cake–the loaf that sinks straight to the bottom of your stomach and lives there for some time, during which you'll want to nap.

What we don't talk about is squishy cake–the kind that gives a little when you press a finger in it and then bounces back, recovering from your violation. Squishy cakes are light enough to snack on and chewy enough to distinguish themselves from air. You can eat a lot of it (yes, with your hands) and, more importantly, you'll want to. In 2015, I'm going to make more squishy cakes. I'm going to describe cakes as squishy and people are going to nod in understanding and ask to share. I'll probably say no.

It's glutinous rice flour–ground from the same grain used to make sticky rice–that makes this cake chewy, gummy, and a little bit gelatinous (in the greatest possible sense). If you've ever had Japanese mochi or Filipino palitaw, you'll understand this cake's playful stretchiness and light stickiness. For an even more intense textural experience, leave out the tablespoon of baking soda that gives the rice flour a major boost and you'll come away with something even more closely resembling a giant sheet of mochi.

If the texture of the cake isn't what you were expecting from the photos, neither is the taste. The chocolate flavor tips more towards mild than dramatic, reminiscent of chocolate Teddy Grahams, which, after the chocolate chip grahams, were always the best in the variety box. If you're unsatisfied with that subtlety, bake with flavored sugars. I made this cake for the first time using Mexican chocolate-flavored sugar because I was out of plain, and it added dimension to the cake.

A note on mochi: I love mochi. I love mochi so much, I named my cat Mochi. But not all people like its smushy texture and delicate flavor. I do not understand these people, but they do, indeed, exist. There are even some people who love me very much and who respect my love for mochi but who do not love mochi themselves. This is okay. I will be at peace with this. If you know you do not like mochi, I fear you will not like this cake. It's worth a shot, but do not say I didn't warn you.

This recipe is fine, and I'm not someone who has an issue with the texture of mochi, but I wish there was something more than just the texture to enjoy. Flavor-wise, these were lacking. The photo for the recipe made me hopeful that these would be really chocolaty, but that wasn't the case. They made me want a fudgy brownie. I like sweets, and sweet things so these would probably be perfect for the "not too sweet" crowd who just want a little pillowy bite. My husband and kid thought they were good, but at the same time, no one ate them.

Literally what I have always wished brownies were, squishy yet moist texture, dark and chocolatey without being too sweet. I have made these 5 times since discovering this recipe. I have varied the amount and types of chocolate depending on what I had on hand, as well as the amount of sugar, and it came out great every time.

Great recipe! I don't like overly sweet desserts and worried that 2 cups of sugar would be too much so I put in a little less, maybe 1 3/4 cup and only had dark chocolate chips on hand so used that and the cake tasted wonderful and not sweet at all. I've never had luck baking brownies from scratch and this was a complete success and I loved the texture and so did the kids. I'm a big fan of rice cakes and this is a light version of it and perfect for those that may not like the super sticky and dense rice cakes and this is also a great gluten free option that I may need to bake for school functions.

Callan C. November 15, 2021

This recipe was simple to make and came out perfectly! It tastes just like a brownie or classic chocolate cake, but has a pleasantly bouncy texture that stays moist (without being dense).

ShaLaLa2009 August 15, 2021

My family loves this recipe! We made it as written the first time, and even the texture skeptics loved it. It was a bonus that the cake was delicious for days after baking. So good and so easy.

For the 2nd time we made it, my 9-year-old and I decided to have a mochi mayhem bake-off. He came up with a bunch of mix-ins to try: chocolate chips, peanut butter, pocky, gummy bears, peppermint patties, mini-marshmallows, and peanut butter cups. We made the batter as written and then took spoonfuls out, which we mixed with whatever mix-in and then baked up in a mini muffin pan to see which additions he liked. The mini muffins baked up fast, and if you do this, definitely put a larger baking pan underneath the muffin pan to catch any overflow. (Marshmallows were a disaster!) It was super fun. His fave was the pocky, and I loved the chocolate chip & peanut butter combo. Great recipe! We will keep making it.

We’re from Hawaii and wanted to take mochi to an event at my daughter’s new school in Colorado. Just made this recipe (doubled the batch) and it’s delicious!!! Just like a dessert from back home. Will definitely make again!

Cheryl July 21, 2018

Hi, I only have a 9" x 13" glass baking dish at home. Would that work for this recipe? Appreciate any insights/advice! Hoping as far as possible to not botch my first attempt... Thanks!

hanne November 15, 2018

Cheryl, I'm betting that you tried the recipe anyways and I hope it turned out great. I always use a glass 9" x 13" when I make this recipe and it turns out nicely every time.

Cheryl January 8, 2019

Hi! Happened to bake this again today and saw your reply. YES I did try it the last time and it was awesome!! :D Thanks :)

egam March 8, 2018

So good!! I added a tablespoon or so of instant espresso which was delicious. I don’t think I incorporated everything as well as I should have into the melted chocolate so I put the mix through a strainer before baking .

tia December 16, 2017

I tried freezing the leftovers and I am happy to report that they freeze well! I cut the cake into pieces and wrapped them in plastic but I bet you could freeze bigger pieces, too. I just let it sit on the counter to defrost. It's not quite as good as fresh, but it's a nice thing to have stashed away for the occasional treat!

Caitlyn December 6, 2016

Since I first came across this recipe just about 2 years ago, it is my go-to baked good for potlucks, bake sales, or just because. Everyone always goes wild for it. I am curious if anyone has experimented with additions. My thoughts were to add chocolate chips to the batter before putting in the pan to bake, perhaps to give a little bonus, gooey chocolate treat. I'm also curious if anyone has made a cake with this, in the sense that you added some sort of filling and layered this cake on itself? The only way I can bake is if I follow recipes to a T so any insights on anyone's experiments would be appreciated (Such as Katy's experimentation with nutella. Yum!)! Thank you!

katy March 2, 2016

I used Nutella ~6-7 oz, instead on chocolate chips and it came out amazing. Thanks for the yummy recipe!!

grace January 28, 2021

Hi, did you then omit the 2 cups of sugar? because nutella is pretty sweet. thanks in advance!

Maya M. December 9, 2015

I wanted a moister cake like texture could I use chocolate pudding in a box along with sugar and mochi glutinous powder?

Andreana L. August 3, 2015

I made this yesterday and gave it to my parents in law and good neighbors. They all loved it! It's not too sweet nor dense and the springy squishy texture is wonderful. I am curious if anyone has tried green tea version of this cake. I'd appreciate it if you can share how much green tea powder/measurements to mix as well as whether to incorporate it into the flour or with the butter.

Sarah J. August 3, 2015

I haven't tried a green tea version, but we do have a variation on this type of cake, with green tea and coconut, here: It's not quite the same light texture, but you could use the amount of matcha in that recipe as a starting point! I'd incorporate it into the dry ingredients.

Andreana L. August 4, 2015

Thanks Sarah, I'll give it a try with green tea =)

Jennifer M. July 18, 2015

Do you think you can freeze leftovers?

witloof June 28, 2015

I made this for a potluck dinner on Saturday night and it flew right off the table. The gluten free people were thrilled! I added a tablespoon of instant coffee to the chocolate mixture and used homemade vanilla sugar. Everyone loved it. I'd definitely make this again.

Nancy Y. June 25, 2015

I followed this recipe exactly how it is. It was DELICIOUS and so easy. I let it cook for a full 60 minutes and was still worried that it was undercooked in the middle. It was fine though and perfectly cooked! I highly recommend this -- my coworkers and friends loved it!

Sarah J. June 25, 2015

Hooray! So happy to hear this.

Farah May 19, 2015

Hi Sarah,
This was was good! Nice and squishy and not overly chocolate-y. (I reduced the sugar to 86g as my mum can't take sweet stuff.) Thanks for the recipe!
I like it all squishy but my daughter would prefer it a little less squishy though. Hence, am planning to leave out the baking soda the next time. However, I came across some recipes which used baking powder (and a lot less milk) instead. Would the texture be very different if using baking powder instead (of baking soda or with no leavening at all) do you think?

LeBec F. May 19, 2015

farah, leaveners- i.e. baking soda and bak powder- are what would make the mocha cake LESS squishy because they cause rising of/air in the batter. So, if anything, if you wanted less Mochi and more Cake- you would use more leavening and/or some flour. It is the mocha (think short grain rice all stuck together) that is squishy because it is rice and not wheat flour.

Farah May 21, 2015

Alright, will give it a try. Thanks for the info. :)

MMitra April 15, 2015

I made this last night after getting all the ingredients together. It's delicious! I'm sharing it with my food exchange buddy today! Thank you!

Sarah J. April 15, 2015

That warms my heart!

LeBec F. April 15, 2015

p.s. sarah, I'm always wanting to experiment and add stuff! Any thoughts about doing a filling layer that bakes along with the cake? Could you divide the base into 2 batches- 1 chocolate and 1 different (maybe green tea mochi). Is the mochi batter thick enough that one could lay down a layer of chocolate and then a green tea mochi batter layer and lastly choc. again-- and have the layers stay distinct?
And have you tried any other experimenting w/ additions: nuts, sesame seeds, dried fruit, extracts, coffee powder....? If certain things have been tried but were not good, that would be v helpful info! Thx again for this inspiration! (I'm getting all these ideas because we have a new Korean bakery here in Boston,
and they make fried mochi donuts filled with adzuki paste (anh) and I'm addicted!)

LeBec F. April 15, 2015

sarah, I hope I didn't insult you with my ideas. Very inspiring recipe!

Sarah J. April 15, 2015

No—you did not insult me at all! I just haven't tried these things. I desperately want to visit that bakery in Boston because it sounds amazing, and I'd love to know how the cake turns out with two layers! I haven't tried using brown rice powder or flour—I'm not sure it would work because the recipe relies on glutinous rice for its texture!

LeBec F. April 16, 2015

hi sarah, whew! so, 2 things for you to know:
1) short grain sticky brown rice does exist I believe, so SOMEBODY must make flour/powder from it!
2) I wrote Bob's Red Mill and their brown rice flour/powder is NOT from brown sticky rice. So I am still looking for some.

Sarah J. May 19, 2015

Thanks for the info!

LeBec F. April 15, 2015

sarah, one more reason to admire your 52 contributions! Tell me, have you ever tried using brown rice powder/flour? I bought some that appears korean but it doesn't say ANYthing other than Brown Rice Powder, and I don't know if it is sticky rice powder or just regular brown rice...!
