Chocolate & Peanut Butter Surprise Cupcakes

Last night we celebrated my mom’s birthday, of course I was put in charge of dessert. She wanted Chocolate and Peanut Butter Cupcakes, her favorite, now I of course couldn’t make just a simple Chocolate and Peanut Butter cupcake, I needed to make it more fun then that. It was the perfect opportunity to try out the surprise cake technique I’ve been seeing all over Pinterest, only I’d be using it in a cupcake.

Chocolate and Peanut Butter cupcakes are one of my favorite flavor combinations, I must get it from my mother. There’s just something about a moist chocolate cake topped with silky peanut buttery buttercream. Did I mention that Reese’s cup on top? Yeah, that makes it pretty good too! 

Oh, but the surprise, yeah that’s the best part! I cored out the cupcakes and filled them with mini Reese’s Pieces! 

Awesome, right?
