Ingredients
Scale
Base Ingredients
- 1 cup unsalted butter (at room temperature)
- 1 cup light brown sugar, packed
- ¾ cup granulated sugar
- 2 large eggs
- 2 teaspoons vanilla extract
Dry Ingredients
- 3 cups all-purpose flour
- 1 teaspoon baking soda
- ¾ teaspoon salt or 1 teaspoon kosher salt
Mix-ins
- 1 cup chocolate chips (plus more for topping if desired)
- 1 cup M&M’s (plus more for topping if desired)
Instructions
- Preheat and Prepare. Preheat your oven to 325°F. Line a 9×13″ pan for thicker bars or a 15×10″ pan for thinner bars with parchment paper or foil, leaving an overhang for easy removal. Spray the pan with non-stick spray.
- Cream Butter and Sugars. In a large bowl, use a mixer to cream together the room temperature butter, light brown sugar, and granulated sugar for about 1 minute until well combined and creamy.
- Add Eggs and Vanilla. Add the eggs and vanilla extract to the creamed butter and sugars. Mix on medium speed until fully combined and smooth.
- Incorporate Dry Ingredients. Add the all-purpose flour, baking soda, and salt to the wet ingredients. Stir gently just until everything is combined, being careful not to overmix.
- Fold in Chocolate and M&Ms. Gently fold in the 1 cup of chocolate chips and 1 cup of M&M’s, reserving about ¼ cup of each to sprinkle on top later.
- Form the Dough in the Pan. Scoop the cookie dough into the prepared pan and press it down evenly to cover the bottom. Sprinkle the reserved chocolate chips and M&M’s evenly across the top for extra color and texture.
- Bake. Bake in the preheated oven for 30-35 minutes if using the 9×13″ pan or about 20 minutes if using the 15×10″ pan. Bake until the top is lightly golden brown and set.
- Cool and Slice. Allow the baked cookie bars to cool completely in the pan on a wire rack. Once cooled, use the parchment or foil overhang to lift the bars out. Slice into 24 squares and serve.
Notes
- M&M’s: Use regular or themed colored M&M’s to customize the bars for any holiday or occasion.
- Storage: Store cooled bars in an airtight container for up to 3 days. For longer storage, freeze up to 3 months. Thaw for about an hour before serving and warm briefly in the microwave for 10-15 seconds if desired.
