Mine is probably your typical boxed cake mix. I store several in the pantry, all flavors, some probably not even made any longer, odd flavors etc. My favorite is Orange Supreme due to husbands favorite cake being Orange Dreamsicle Cream cake with like frosting. But with other cake mixes, I make several things out of them and then think they're pretty versatile.
Cookies/cupcakes/cakes/quick breads/breads. I have even added a tablespoon or two to crepes I've made or added same amount to add flavor to other things, even sweeten up sauces for over fruit like with sour cream or cream cheese.
Do you have a go to convenience food that you always find yourself reaching in the pantry for? What is it and what do you do with it?
