Follow the recipe on Bisquick box. (I added orange food coloring).
Follow the recipe on box of cake mix of your choice. EXCEPT – if box says recipe makes 24 cupcakes, pour into 12! (and so on and so forth…) It will look like your cupcakes are about to spill out and explode, but I assure you, they will not. Bake for the long cooking time (i.e. if the box says bake 19-24min, use the 24 minutes).
I always ice my cupcakes with vanilla or white icing so I can use food coloring to match my ‘theme’. I’m much too
cheap thrifty to buy sprinkles.
