To prepare a diabetic yellow cake and fluffy frosting baked goods recipe, first you need to prepare your ingredients. First, you will need your flour, baking powder, sugar, cocoa, eggs, vanilla, and butter. You can find these ingredients in the baking section of most grocery stores. Then, add your dry ingredients to the wet ingredients and mix them together until everything is well combined. Next, pour your cake batter into your greased and floured cake pan. Bake the cake for 35 to 40 minutes, or until the toothpick inserted into the center comes out clean.
