These vanilla cupcakes with fluffy chocolate buttercream frosting are mini birthday cakes in just a few bites! Dressed up with festive rainbow sprinkles, these yummy cupcakes are mouthwatering and delicious! Although most frostings can be overly sweet or waxy, this chocolate buttercream is light and simply the best!
**NOTE: There’s a special surprise in every bite; I scooped out some of the cake, so the cupcake is filled with extra chocolate buttercream frosting. Enjoy!
