Instructions

Preheat the oven to 325°F and line a 9 x 13-inch baking pan with parchment to easily remove the baked cookie bars.
In the bowl of a stand mixer or in a large bowl with an electric mixer, cream together the butter, brown sugar, and granulated sugar until light and fluffy. Add the eggs and vanilla; mix until combined.
Into the bowl, add the flour, baking soda, and salt; stir until combined. With a spatula, fold in ¾ cup each of the chocolate chips and M&M's until just combined. Be careful not to overmix the dough.
Lightly spray the parchment with non-stick cooking spray. Spoon bar cookie dough into the prepared pan and spread evenly. Add the remaining ¼ cup M&M's and chocolate chips to the top of the dough.
Bake for 30-35 minutes, or until the top is just beginning to turn golden brown. Cool the bars completely before removing them from the pan and cutting them into squares.
