Mochi is a Japanese cake made with sweet rice flour. Plain mochi is delicious and one of my most anticipated treats when going to Little Tokyo in downtown LA.

This buttery coconut rice cake takes plain mochi to a new level of moistness and flavor. A favorite in Hawaii and soon to be a favorite in your house.

I know what you’re thinking though; you see the words “Gluten Free” in a recipe and you may say, “That’s not for me, I can eat gluten therefore I should make a regular cake and not a gluten free cake”. I hear you. Although I only came across butter mochi cake when looking for a dessert to make for a friend with celiac disease, it quickly became one of my family and friends’ favorite treats.

And it’s also is a best seller at the church’s bake sale! It really stands out in an endless sea of breads, cookies and brownies. I have included a free download of catchy tags for bake sales at the bottom of this post.

I’ve tweaked the basic recipe to make it extra “coconuty” (like my daughter would say) and added the sesame seeds, which blend perfectly with the Asian theme.  A friend, whose wife is Hawaiian, admitted in confidence my butter mochi was better than his wife’s. (Well I hope she’s not reading this right now. No, really, yours is good too and was my first inspiration!).

Definitely the perfect dessert for a tropical party.

Here’s a visual of the ingredients and of the finished product. Check out the full recipe at the bottom of this post.

Make sure you use a sweet rice flour and not just rice flour. They’re made of different types of rice.

Although not the one pictured, this is the one I recommend:

After the mixture is poured in the baking pan, the sesame seeds get sprinkled on the top like this:

      Thank you so much! There is no fascinating history behind the recipe. I just LOVE mochi and knew a Hawaiian gal who made mochi cake for her parties. I liked it but decided to make my recipe with lot more coconut flavor. It’s a true favorite at our house and gets real compliments when I bring it somewhere.
