Reese's Peanut Butter Cupcakes

Reese’s Peanut Butter Cupcakes Serves: 16-20

  • Cupcakes:
  • 1 (15.25 ounce) chocolate cake mix
  • 2 eggs
  • 1 cup sour cream
  • ½ cup milk
  • ⅓ cup vegetable oil
  • 32-40 Reese's mini peanut butter cups (, unwrapped)
  • Peanut Butter Frosting:
  • 1/2 cup unsalted butter
  • 1 cup creamy peanut butter
  • 2 cups powdered sugar
  • 1 teaspoon vanilla extract
  • 3 tablespoons milk ((or more as needed))
  1. Preheat oven to 350 degrees and line cupcake pan with paper liners.
  2. For the cupcakes: Combine the cake mix, eggs, sour cream, milk, and vegetable oil in a large bowl until incorporated. Scrape sides of bowl and then beat on medium-high speed for 3 minutes.
  3. Fill cupcake liners halfway full and press one peanut butter cup into the center of each. Depending on your cupcake pan it could make about 16-20 cupcakes. Bake for 15-18 minutes or until done. Cool.
  4. For the Frosting: In a mixing bowl, cream butter and peanut butter until fluffy. Add the powdered sugar, vanilla, and milk and continue creaming until well blended. Blend on low speed until moistened. Beat at high speed until frosting is fluffy adding more milk if needed.
  5. Pipe frosting onto cupcakes. I used a wilton 2D tip. Garnish with the remaining peanut butter cups chopped.

If you’re feeling extra fancy drizzle some melted peanut butter and melted chocolate (chocolate chips melted with 1 tablespoon butter or 1 teaspoon vegetable oil).

    We are huge fans of yours at our house. My 12 year old daughter is doing a bake-off fundraiser with her YWS for Girls Camp this year and both of her desserts are from your page. (This one and your homemade oreos.) We have never made anything from your cookbook or website that we didn’t like (and we’ve done a lot)! Thanks for being such a reliable source for yummy food! 💖

  8. I made these for the first time the other day and they are gorgeous!!! They are also incredibly simple to make so thank you!!!!

  9. These were delicious. The frosting was perfect. My husband bought German chocolate cake mix and I felt like the cupcakes needed more chocolate. Next time I will make by hand. For the frosting I whipped the butter for 3 minutes, added the peanut butter and whipped another 2. In between each half cup of powdered sugar I whipped for a minute. I have never been patient in baking but this was worth it.
