Chocolate Mochi Cake

Chocolate Mochi Cake_n

Dense, lightly-sweetened chocolate cake made with rice flour offers a satisfyingly sweet bite at the end of a Japanese meal.

I learned today that there is a difference between rice flour and glutinous rice flour (mochiko flour). Rice flour can be used in baking. Glutinous rice flour is used to make sweet desserts like mochi, which is what I wanted to learn how to make. I also learned that I purchased twenty-five pounds of the wrong kind of flour in our annual shopping trip. What to do?

Obviously, I had nothing to lose by experimenting. The following recipe is a modification of one published by The Polynesian Cultural Center. The results were quite tasty. Adding half a tablespoon of baking soda will give this recipe a more cake-like result if you prefer. Following the recipe below will yield a dense mochi-like cake.
