Start with one boxed cake mix. You will follow the directions but you'll be adding more ingredients. Baking temperature and baking time will be on the box. I used a Betty Crocker cake mix for this tutorial but any cake mix will do, just follow the directions and add the extra ingredients.
Step 1: Extras
1/2 cup flour
1/2 cup sugar
1 teaspoon baking powder
Use a whisk to stir all dry ingredients together.
