These quick and easy Christmas cookie bars are full of M&Ms and chocolate chips, making them perfect for cookie exchanges, neighbor gifts, or a family treat during the holiday season.
Preheat oven to 350°F. Line a 9X13 pan with parchment and lightly spray with cooking spray.
Beat butter, granulated sugar, brown sugar together until fluffy. (I use my mixer for this recipe)
Add eggs and vanilla. Mix until combined. Mix in baking soda and salt. Then add flour, mixing until combined. Add chocolate chips and 1 cup M&Ms. Stir by hand until they're evenly distributed.
Spread the dough out evenly into the pan.
Sprinkle the remaining ½ cup M&Ms over the dough.
Bake 35 - 40 minutes in the middle of the oven. Let cool completely. Remove from pan and place on cutting board to cut into pieces with a large knife.
Tip: For extra Christmas charm, use a simple cookie cutter, such as a star or gingerbread man, to cut them out.
