Chocolate & Peanut Butter Surprise Cupcakes

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

Chocolate and Peanut Butter are on of my favorite cake/cupcake flavor combos, though isn’t it everyone’s? There’s just something about a moist chocolate cake topped with silky peanut butter 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?

The Reese’s Pieces surprise was a lot of fun, and it would have been an actual surprise if Matt hadn’t told everyone. The Reese’s Pieces added great texture and I’ll never make Chocolate Peanut Butter Cupcakes without them again!
Plus that creamy peanut butter frosting is pretty damn good too!
So what are you waiting for? Whip up a batch, grab a gallon of milk, and enjoy!

    Could these be any more darling?! I don’t think I have ever baked with sour cream before, but it sounds like it would work well here.

      Sour Cream is amazing when it comes to cakes! You don’t taste it but it makes them so moist!

    I make a similar recipe, but I like how you used sour cream in yours. They look so delicious.

      The sour cream makes such a difference! You can’t taste it but it makes them extremely moist!

    The picture caught my eye because they look perfect! Just thinking I’m going to try this but put the Reese’s Pieces in before they bake. I would think the batter would just cover them. Anyone else try this?

      You could definitely try them that way, I’m sure it would be like adding them to cookie dough.
