This Peppermint Brownie Brittle is a fun chocolate dessert for the holidays! Thin and crispy brownie is loaded with chocolate and peppermint chips for festive flavor and a great cookie exchange treat!
Preheat oven to 325°F. Line a large baking sheet with parchment paper. Coat paper with nonstick cooking spray.
In a large bowl or stand mixer fitted with a paddle attachment, mix together the brownie mix, butter, milk, and egg on medium speed until smooth. Stir in chocolate chips.
Spread half of the batter onto prepared baking sheet, spoon peppermint chips evenly over batter.
Bake 25 to 28 minutes or until center is set. Slide parchment paper with brittle onto a cooling rack to cool completely. Reline the baking sheet with more parchment paper and bake the remaining batter.
