Ingredients Needed:

  • Dry cake mix
  • Egg whites
  • Diet soda

Does this work with any flavor cake mix? Yes. If you don’t want to make chocolate cake, you can use any flavor/brand. Just be sure to stick with a standard size box, approx 15-18 oz in size.

Diet Soda: Again, any flavor will work. I like to stick with a basic diet lemon lime soda( ex: 7UP) for a white cake and a basic diet cola for chocolate.

What about Frosting? The cake picture is frosted with my Chocolate Buttercream Frosting- No Powdered Sugar Required. However, you can eat this plain or frost it with your favorite frosting, whipped topping ( ex: Cool Whip) or whipped cream.

A few notes:

  • The nutritional value listed in the recipe card is just for the cake. If you frost your cake, it will be different.
  • Want to make cupcakes instead? Make the batter as noted. Then, bake according to the cake mix package for cupcakes.
  • With that said, you can also use this batter to make a loaf cake, bundt cake or 13 x 9 sheet cake.
