Oreo Peanut Butter Brownie Cupcakes

Prep Time: 15 minutes | Cook Time: 25 minutes | Yield: 12

  • 1 package, store bought brownie mix with chocolate chips (I used Ghirardelli)

  • 1 egg

  • ¼ cup, water

  • ¼ cup, vegetable oil

  • 2 sleeves, Oreo cookies (12 cookies in total)

  • Your choice of filling (I used 1 cup of peanut butter; creamy or chunky both work)


  1. Preheat oven to 350 degrees F.

  2. Line a cupcake pan with cupcake liners.

  3. In a medium mixing bowl, combine brownie mix with ¼ cup water, ¼ cup vegetable oil, and the egg until just blended.

  4. Put one Oreo into each cupcake liner.

  5. Top each cookie with your filling of choice (I used 1 teaspoon peanut butter,) 1 teaspoon of Nutella, 2 individual soft caramels, or 1 peppermint patty will also work).

  6. Carefully add brownie batter to the top of the cupcake liners.

  7. Bake for 20-25 minutes, checking for doneness after 15 minutes. (Note: The sides will be firm to the touch when done, but the top will remain soft due to the peanut butter filling.)

  8. Cool 3-4 minutes in-pan, then transfer to a serving plate and allow to cool completely.


Store whatever you don’t eat in airtight container, and enjoy the yummy gooeyness!
