A few years ago, my grandaughter asked me to make something for the fundraiser in school. I made cupcakes in an ice cream cone...and made it look like actual ice cream. I made 2 dozen - half a dozen mysteriously disappeared before even getting to the school..LOL.
They were gone in less than 15 minutes. Now everytime there is a fundraiser, guess who gets to bake..although now the girls help me and basically do it on their own. Another thing that goes well is shape cakes...can't remember the URL but you could shape the cake into a ball...that would be easy!!!!! I once made a popcorn cake....it went for $1 more than the others!
