To make things easier, we recommend traditional store bought boxes of cake mix. Just add butter or oil, egg and water. Super easy.
It takes about two boxes. There will be some left over batter which is perfect for a dozen cupcakes.
We have even experimented with gluten free batters and they came out great. Just need to fill a little higher b/c they don't rise as much.
However, feel free to make your own mix from scratch if you like. Just make sure to prepare enough batter for two 8 inch cakes.
;) Life is what you make it! So bake it sweet.
