Ingredients

Scale
  • 1 box brownie mix (plus required eggs, oil, and water)
  • 1/2 cup unsalted butter, softened
  • 1/2 cup brown sugar, packed
  • 1/4 cup granulated sugar
  • 1 egg
  • 1 tsp vanilla extract
  • 1 cup all-purpose flour
  • 1/4 tsp salt
  • 1 cup mini chocolate chips (divided)
  • 2 cups white chocolate chips
  • 1 (14 oz) can sweetened condensed milk
  • 1/2 tsp peppermint extract
  • Green food coloring (optional)

Instructions

  1. Preheat oven to 350°F (175°C). Line a 9×13-inch pan with parchment paper or foil, leaving overhang for easy removal.
  2. Prepare brownie mix according to package instructions and spread evenly into the bottom of the pan. Bake for 20 minutes, then set aside to cool slightly.
  3. In a medium bowl, cream together butter, brown sugar, and granulated sugar until light and fluffy.
  4. Add egg and vanilla extract, mixing well. Stir in flour and salt until just combined. Fold in 1/2 cup mini chocolate chips.
  5. Carefully press the cookie dough layer over the cooled brownie base.
  6. In a saucepan over low heat, combine white chocolate chips and sweetened condensed milk. Stir until smooth and melted.
  7. Remove from heat, add peppermint extract and green food coloring if using. Stir to combine.
  8. Fold in the remaining 1/2 cup mini chocolate chips, then immediately pour fudge mixture over the cookie dough layer, spreading evenly.
  9. Refrigerate for at least 2 hours, or until fully set.
  10. Lift out of the pan using parchment overhang, slice into squares, and serve.

Notes

  • Make sure brownie layer is fully cooled before adding cookie dough to avoid melting it.
  • Use high-quality white chocolate chips for a smoother fudge consistency.
  • Store bars in the refrigerator for up to 5 days or freeze for longer storage.
