Ingredients
Scale
Cookie Base
- ½ cup unsalted butter (melted)
- ½ cup packed light brown sugar
- ⅓ cup granulated sugar
- 1 large egg (room temperature)
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour
- ¼ teaspoon salt
Mix-ins and Toppings
- ½ cup semi-sweet chocolate chips
- ½ cup red and green M&M’s (divided: ⅓ cup in batter and remainder for topping)
- ¼ cup Christmas jimmies
- Christmas sprinkles (for sprinkling over the baked cookie bars, optional)
Instructions
- Prepare Baking Pan: Preheat your oven to 350°F. Lightly brush an 8×8-inch square baking pan with some melted butter and line it with parchment paper, ensuring there is a 2-inch overhang on two sides for easy lifting later.
- Mix Wet Ingredients: In a large bowl, whisk the remaining melted butter together with the light brown sugar and granulated sugar until smooth. Add in the egg and vanilla extract, whisking until fully incorporated and the mixture is creamy.
- Combine Dry Ingredients: Add the all-purpose flour and salt to the wet ingredients. Mix gently just until the flour is moistened to avoid over-working the dough which can toughen the bars.
- Fold in Mix-ins: Gently fold in ½ cup of the semi-sweet chocolate chips, ⅓ cup of the red and green M&M’s, and the Christmas jimmies into the batter, distributing evenly.
- Transfer and Top: Pour the batter into the prepared baking pan and smooth the surface with a rubber spatula. Evenly sprinkle the remaining M&M’s over the top to create a colorful festive look.
- Bake: Place the pan in the preheated oven and bake for 20 minutes or until the top is golden brown and a toothpick inserted into the center comes out clean, indicating the bars are fully baked.
- Cool and Serve: Remove the pan from the oven and place it on a wire rack. If desired, sprinkle Christmas sprinkles over the warm bars for additional decoration. Let the bars cool completely in the pan. Once cooled, use the parchment overhang to lift the bars out and transfer them to a cutting board. Cut into squares and serve.
Notes
- Ensure the egg is at room temperature for better mixing and texture.
- Do not overmix the flour into the batter to keep the bars tender.
- Parchment paper with overhang makes removing bars from the pan easier and cleaner.
- Feel free to customize the toppings with other festive candies or nuts.
- Store leftovers in an airtight container at room temperature for up to 4 days.
