Chocolate Mochi Snack Cake

March 12, 2015


Author Notes: While this cake looks dense and rich and indulgent and could pass for a nearly-flourless chocolate cake, it is none of those things. Mochi cake—which is more squishy than gooey and more subtle than sweet—is better. Why? It starts with the fact that, with its surprising spring and spryness, it is light and inhalable.

The texture is soft and chewy, and the flavor is surprising, too: The chocolate is subtle, more along the lines of a chocolate-flavored graham cracker than a molten lava cake. If you'd like a deeper or more dimensional flavor, I'd recommend baking with a spiced sugar (like cinnamon sugar).

This recipe is from the The Polynesian Cultural Center by way of Use Real Butter.

In This Recipe

Directions

  1. Preheat the oven to 350° F and grease a 9- by 13-inch baking pan.
  2. Whisk together the flour, sugar, and baking soda in a large bowl. Set aside.
  3. Heat the butter and the chocolate chips together in a small saucepan over low heat, stirring frequently until you have a smooth mixture.
  4. Pour the melted chocolate and butter into the bowl of a stand mixer fitted with a paddle attachment. With the mixer running on low, add the evaporated milk, vanilla, and eggs and mix until incorporated.
  5. Add the dry ingredients and mix on low until the batter is smooth and lump-less. Pour into the prepared pan and bake for 45 to 55 minutes, until the cake no longer jiggles. Remove from oven and let cool before serving.
  6. This cake should be stored at room temperature rather than refrigerated.

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!

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 .

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!

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!

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

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

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.

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: https://food52.com/recipes/34999-matcha-coconut-mochi-cake. 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.

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

Do you think you can freeze leftovers?

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.

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!

Hi Sarah, <br />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! <br />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?
 
LE B. 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. :)

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!

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?<br />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,<br />and they make fried mochi donuts filled with adzuki paste (anh) and I'm addicted!)
 
LE B. 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!
 
LE B. April 16, 2015
hi sarah, whew! so, 2 things for you to know:<br />1) short grain sticky brown rice does exist I believe, so SOMEBODY must make flour/powder from it!<br />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.

Thanks for the info!
 
LE B. 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...!
 
donna B. March 31, 2015
hi,<br /><br />i see the the recipe says to store at room temperature which is great because i'd like to make it and ship it 2 day air. do you think it'll travel well and will it mold if it has evapororated milk in 2 days? thanks. i'm dying to try this recipe and i can't even eat cake. thank you. donna in snohomsih
 
Erica March 24, 2015
I can't eat egg. Is there anything I can substitute for them in this recipe?
 
Joy H. March 23, 2015
I made this yesterday and couldn't stop eating it. The texture is so different from anything else I've ever had, kind of in between regular cakes and mochi. I have a silly question though: what makes this a "snack cake" vs. just a "cake"? I've seen that term used to describe a few other recipes on this site and am wondering what the difference is.
 
Beth March 19, 2015
Is it possible to use almond flour rather than rice flour?
 
Author Comment
Sarah J. March 19, 2015
I'm afraid the texture won't be at all the same. Glutinous rice flour is really the key ingredient here!
 
Beth March 19, 2015
Got it. Thanks--can't wait to try it! :)
 
Melanie March 16, 2015
I halved this recipe, and baked it in a 9 inch round cake pan. I only used 3/4 c. of organic cane sugar and substituted full fat coconut milk for the evaporated milk. I baked it for 35 min. The texture is really interesting (springy, light) and the flavor is delicious. A nice alternative to wheat flour and super easy for a week night dessert. Thank you!

Melanie, it is 52ers like you that I appreciate so much because you contribute to the whole body of knowledge about a recipe. And this is particularly important with such a new ingredient-glutinous rice flour/powder! thx so much.
 
Melanie March 30, 2016
Just saw your comment, Le Bec Fin. Thank you! I was just recently wondering how folks who post recipes feel about those of us who make adaptations to recipes as written. :-)
 
Debbie March 15, 2015
I would love to make this, but I don't have a stand mixer. Should I use an electric hand held mixer on low speed, or hand mix?
 
witloof March 16, 2015
You can always use a hand mixer for cakes. Stand mixers are rarely necessary for a recipe, in fact.
