Mini Peanut Butter Cup Brownies

mini peanut butter cup brownies on parchment paper on a wire cooling rack.

Deliciously fudgy, mini peanut butter cup brownie bites are the perfect tiny dessert for when you need just a little something sweet. Full of rich, dark chocolate and real peanut butter cups, just one mini brownie is super satisfying!

Ingredients

Scale
  • 3 oz bittersweet chocolate, roughly chopped
  • 1/2 cup (1 stick) butter
  • 3/4 cup sugar
  • 1 tsp instant coffee or espresso powder (optional)
  • 1/2 tsp vanilla
  • 1/4 tsp sea salt
  • 2 eggs
  • 1/2 cup white whole wheat flour (or all purpose flour)
  • 24 mini peanut butter cups (I use dark chocolate)

Instructions

  1. Preheat oven to 350° F. Lightly oil a mini muffin tin, or line with paper liners.
  2. In a large microwave-safe bowl, melt butter and chocolate by microwaving in 30 second intervals, stirring in between.
  3. Add sugar, coffee granules and salt. Stir to combine.
  4. Add vanilla and eggs and whisk well until fully combined.
  5. Stir in flour.
  6. Scoop batter into muffin tin with a small scoop. Bake for 12-15 minutes, or until a toothpick inserted in the center comes out clean. Careful not to over-bake or the peanut butter cups will be hard to push in!
  7. Remove brownies from oven and immediately press an unwrapped peanut butter cup into the center of each brownie.
  8. Let brownies cool for at least 10 minutes before removing to a wire cooling rack.

Notes

  • I use bittersweet chocolate because I don't like my brownies too sweet. You can also use chopped dark chocolate or even semisweet.
  • Be sure to unwrap the peanut butter cups while the brownies are baking so that you can push them in immediately after removing the brownies from the oven. If the brownies start to firm up, you'll have peanut butter cups sticking half way out of the tops!
  • Store brownies in an airtight container at room temperature for up to 5 days.
