A fluffy vanilla cupcake topped with a marshmallow buttercream frosting and topped with a rice krispie treat!
* This cupcake recipe makes about 30 cupcakes. So to frost them, I always make two batches of the frosting. If you don't plan to frost all the cupcakes- you could make one batch of frosting for about 12-15 cupcakes. You could then freeze the rest of the cupcakes (unfrosted) in a zip-loc bag or another airtight container.
* I used storebought rice krispie treats, but you could definitely use homemade.
*If you don't have buttermilk on hand, simply add 1 tablespoon of white vinegar or lemon juice to each cup of milk and let sit for 5 minutes.
* If you don't have cake flour on hand, measure out a cup of flour, remove one tablespoon. Add 1 tablespoon of cornstarch. Do this for every cup of flour that you need.
