½ cup Sugar in the Raw blended till very fine
Preheat oven to 350 degrees. Oil and dust a round cake pan with potato starch. Combine cocoa and sugar in the boiling water and cook until the sugar is dissolved. Beat butter and eggs together. Add yogurt and vanilla to egg mixture, beating until very well combined. In a separate bowl, sift together dry ingredients, (baking soda, salt, flours, and starches.) Add the dry ingredients to the egg mixture beating until well combined (about 1-2 minutes.) Pour batter into prepared pan, and bake until toothpick inserted into the center comes out clean, about 25-30 minutes. Let cool for 5-10 minutes. Remove cake from the pan and dribble glaze across the top. Serves 6. Double the recipe for a two layer cake. If you like things extra sweet try doubling the sugar.
