Chocolate Peanut Butter Cupcakes

Do you ever have moments where you are daydreaming in the car and a brilliant idea hits you? That’s what happened with these cupcakes.

The idea to make a chocolate cupcake with peanut butter buttercream frosting was very logical. Then I had the idea to drop a Reese’s mini peanut butter cup right into the center, brilliant. THEN I take it over the top with some chocolate curls and another peanut butter cup on top.

Pure Chocolate and Peanut Butter Genius.

These Chocolate Cupcakes are so easy to make because they start with a classic box mix. Just a few tweaks and it's a bakery style cupcake worth Instagram!

  • Author: Shawn Syphus | I Wash You Dry
  • Prep Time: 10 minutes
  • Cook Time: 15 minutes
  • Total Time: 25 minutes

Ingredients

  • 1 box Chocolate Cake Mix
  • *ingredients to make box mix (eggs, water, oil)
  • 24 Reese’s Miniature Peanut Butter Cups, foil and wrappers removed

For the Frosting:

  • 1 cup butter (16 tablespoons), softened
  • 1 cup creamy peanut butter
  • 2 cups powdered sugar
  • 1/4 tsp salt
  • 1 tsp vanilla
  • 2 tbsp heavy cream (or milk)
  • extra Reese’s Miniature Peanut Butter Cups for topping (optional)
  • chocolate bar to make chocolate shavings (optional)

Instructions

  1. Preheat oven to 350 degrees.
  2. Prepare chocolate cake mix according to package directions and fill cup cake liners 2/3 full with batter. Bake for 7 minutes then carefully remove cup cakes from oven and drop the Reese’s Miniatures into the center of the cup cakes. Place back in the oven for 12-15 minutes or until toothpick inserted in center comes away clean.
  3. Cool cupcakes completely on a wire rack.

For the Frosting:

  1. While cup cakes are cooling prepare buttercream frosting by blending butter and peanut butter in a large mixing bowl with an electric mixture until smooth.
  2. Pour in the powdered sugar and salt and mix just until the sugar begins to get moistened (about 45 seconds). Add the vanilla and heavy cream and blend for 30 seconds. Scrape down the sides of the bowl and beat for an additional 4 minutes until the frosting becomes light and fluffy.
  3. Frost the cooled cup cakes using your desired method then top with chocolate curls (see notes) and halved Reese’s Miniature Peanut Butter Cups if desired. Enjoy!

Notes

*You can add some chocolate shavings by using a vegetable peeler to scrape a bar of chocolate onto the frosting.

    Why would you drop in a unwrapped PB cup?
    Now I know better, BUT there are new bakers that would follow this to a “T” and I am not joking, I have a daughter that would.

    These cupcakes look amazingly yummy…we’re getting snow this weekend in the northeast; I won’t mind being snowed in now since I know I’ll be making a batch of these… Thanks for sharing!

  3. If we were ever stranded on a deserted island together, we would get along just fine–my food arsenal would consist solely of peanut butter and chocolate. Maybe you could even bake a batch to bring along before we get stuck! It might help to placate any invaders, and/or creatures with big bat-like eyes…thanks for sharing!

  4. Haha, totally lol’d at your Hobbit thing. I’m pretty sure whenever I make the final decision to watch the LOTR trilogy or whatever, I’m going to have night terrors for the rest of my life as well. So disgusting! However, these amazing cupcakes are anything but gross. They look INCREDIBLE!!

  5. I’m surprised you didn’t like The Hobbit! Great book and great adaptation of the book. (Same with LoTR..) On the other hand, with these cupcakes at the party, I don’t think I would be paying much attention to The Hobbit either, hehe..

    1. I bet I would have appreciated the movie much more had I read the book. My husband loved it, and so did the rest of his family. I am just a wuss, and can’t handle scary movies! LOL
