I searched the internet for all types of recipes, and there really are all types of recipes. add sprite, add creme, add crazy complicated stuff. I just wanted simple.
This is a simple one I found. and it worked out great.
I ended up using a rainbow cake mix leftover in my pantry.
and I totally ran out of butter for the frosting. so instead of it all being powder sugar and milk (and 1/2 tsp of butter) I used some cream cheese and my secret frosting weapon....almond extract.
