Combine batter mixture. Mix for a few minutes. Batter will be thinner than box cake mixes.
Pour batter into a greased and floured 9x13 pan or two 9 inch cake pans. Bake at 350 degrees ( I learned through til, cooking times vary from 30-45 minutes) depending on your pans. Place in fridge to cool.
Combine frosting ingredients in a bowl and mix. Spread over cool cakes. I add chocolate chips in between the layers for a little texture. Decorate and enjoy!
