Prep Time 20 minutes
Cook Time 12 minutes
Dough Chilling 30 minutes
Total Time 1 hour 2 minutes


  • 4 tablespoons unsalted butter softened
  • 4 ounces cream cheese softened
  • 1 large egg room temperature
  • 1 box chocolate fudge brownie mix 17.6–19 oz
  • 3/4 cup creamy peanut butter
  • 3/4 cup powdered sugar
  • 1 teaspoon vanilla extract
  • 1/4 cup heavy whipping cream
  • 3/4 cup semisweet chocolate chips or 6 oz chopped chocolate
  • 1/2 cup lightly salted roasted peanuts coarsely chopped (optional)


  • In a large mixing bowl stir together softened butter, cream cheese, egg, and fudge packet (from brownie mix) until combined. Add brownie mix and stir until just combined.
  • Scoop 24 portions of dough and put them on a tray or plate that fits in the refrigerator. Chill for about 30 minutes or until the dough is still enough to be shaped into neat balls.
  • Meanwhile, beat together peanut butter, powdered sugar, and vanilla; stir until smooth dough forms. Form peanut butter dough into 24 equal balls and put them in the freezer for 30 minutes.
  • Preheat oven to 350°F. Line 2 baking sheets with parchment paper.
  • Once both doughs are chilled, shape the brownie dough into neat balls and the peanut butter dough into neat balls. Arrange brownie dough about 2 ½ inches apart on baking sheet. Press a ball of peanut butter dough into the center and press down slightly.
  • Bake cookies 10–12 minutes or until edges are crisp, then cool on baking sheet 2–3 minutes before transferring to cooling rack to cool completely.
  • Pour cream in a 2 cup liquid measure (or small bowl) and heat for 30 seconds until hot. Add chocolate morsels; let sit 2 minutes to melt. Stir chocolate mixture until smooth and combined. Spread about 1 tablespoon chocolate mixture over each cookie, then sprinkle with chopped peanuts, if desired. Serve.
