Just these few, simple add-ins turns a 39¢ box of cake mix into a more palatable cake.
1- 9 oz Jiffy White cake mix
1/2 cup milk
1 egg, use the whole egg not just the white like the box states
1 Tbsp vanilla
1/2 stick melted butter.
Combine all and bake according to package directions. I used 2- 6 inch pans to make a layer cake, then I frosted with store-bought frosting that I also found lurking in the cupboard and covered the sides in coconut.
