"Rainbow Cupcake Frosting" Could be done on rainbow cupcakes. This looks yummy as well as pretty. I'm not a big fan of sweets, and I have little to no fondness for chocolate cupcakes, but I totally want to eat that.
Vanilla Cupcakes with Vanilla Buttercream Frosting
Gluten-Free Cheesecake-Stuffed Pumpkin Cupcakes- the real recipe link. I wasn't a fan of the frosting. It was entirely too complicated and just tasted like butter. They're amazing without frosting, or would be great with a regular cream cheese frosting:)
