"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.
Homemade Marshmallow Creme - once you've had it you may never buy it store bought again. It's so easy to make and it's like eating fluffy, fresh, heavenly marshmallow clouds. Just try not to eat the whole bowl at once =). Great for a cupcake filling
life cycle of a plant lesson? Sweet Sprout Cupcakes - made your favorite chocolate cupcake recipe, place batter in mini terra cotta pots and place in cupcake pan, bake, make green edible fondant plant sprouts. How fun!
