Well the name says it all. This is the richest chocolate cake around. To make it a 2 layer cake, multiply the ingredients by one half and divide into 2 seperate springform pans. If you don't have springform pans, cover the bottoms in parchment paper or it will stick.
Preheat oven to 350 F degrees. Spray a 9-inch springform pan with non stick cooking spray.
Sift together flours and baking powder and baking soda.
In a saucepan, heat the soymilk on low-medium heat. When it is slightly bubbling, add the cocoa powder and wisk well until it is dissolved. Remove from heat.
Combine the other liquid ingredients in a bowl and whisk well. Add the cocoa mixture and combine. Add the wet ingredients to the dry.
Pour batter into prepared pan, bake at 350 F degree for 25 minutes until a toothpick or butter knife comes out clean. Let cool completely and frost with your favorite frosting. This is from www.theppk.com.
