Course: Dessert
Servings: 9

Ingredients

  • 1 cup unsalted butter softened
  • ½ cup brown sugar
  • ½ cup granulated sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • 2 cups all-purpose flour
  • ¼ tsp salt
  • ¾ cup mini chocolate chips
  • 1 cup crushed Christmas Oreos plus 9 whole Oreos for layering
  • ¼ cup Christmas M&M’s

Instructions

  • Preheat your oven to 350°F and line an 8x8-inch baking pan with parchment paper, leaving a little overhang on the sides to lift the bars out later.
  • In a large mixing bowl, cream together the butter, brown sugar, and granulated sugar until light and fluffy — about 2–3 minutes.
  • Beat in the eggs, vanilla extract, and salt until smooth and well combined.
  • Add the flour and mix until just combined — don’t overmix or the bars can turn dense.
  • Fold in the chocolate chips, M&M’s, and crushed Oreos, saving a handful of each for the top.
  • Press about ⅓ of the cookie dough evenly into the bottom of your prepared pan.
  • Arrange the 9 whole Oreos in a single layer across the dough.
  • Gently spread the remaining cookie dough on top, pressing it out evenly to cover the Oreos.
  • Sprinkle the reserved crushed Oreos and M&M’s over the top for that festive look.
  • Bake for 22–25 minutes, or until the top is golden brown and a toothpick inserted in the center comes out mostly clean (a few crumbs are fine!).
  • Let the bars cool in the pan for about 10–15 minutes before lifting them out and slicing.
