Step-by-Step Instructions
Preheat your oven to 350°F (177°C). Grease a 9×13 inch baking pan with butter or non-stick cooking spray.
In a medium bowl, whisk together the all-purpose flour, baking soda, and salt. Set aside.
In a large mixing bowl, beat the softened butter with the granulated sugar and brown sugar until light and fluffy, about 2-3 minutes. Beat in the eggs one at a time, then stir in the vanilla extract.
Gradually add the dry ingredients from step 2 to the wet ingredients, mixing until just combined. Fold in the 2 cups of M&M’s and the chocolate chips.
Spread the cookie dough evenly into the prepared baking pan. Sprinkle additional M&M’s on top, pressing them lightly into the dough.
Bake for 25-30 minutes, or until the edges are golden brown, and the center is still slightly soft. Be careful not to overbake, as this can result in a dry, crumbly texture.
Allow the MM cookie bars to cool completely in the pan before cutting into squares. Enjoy your colorful and delicious treats!
