How to Make M&M Cookie Bars:

1. Combine dry ingredients: flour, baking powder, baking soda and salt in a medium bowl; set aside.

2. Combine wet ingredients: Add butter, sugar and brown sugar to a large mixing bowl or stand mixer and beat well until creamed together. Add egg and vanilla and mix until combined. Gradually mix in the dry ingredients and mix until combined.

3. Add chocolate: Stir in chocolate chips and m&m’s.

4. Bake: Press dough into a greased 9×13” pan and bake at 350 degrees F. for 22-35 minutes. Remove from pan and let cool completely. Pull up on the sides of parchment paper to remove bars from the pan and cut into squares.

Make Ahead And Freezing Instructions:

To make ahead: The cookie dough can be made 2-3 days ahead of time, stored in the refrigerator.

To freeze: allow baked bars to cool completely after cooking and cut them into squares. Place squares into a freezer safe bag or container and freeze for up to 3 months. Cookie dough can also be frozen for up to 3 months.

Recipes Variations:

• Add nuts: chopped walnuts or pecans
• Substitute the chips: feel free to add or substitute your favorite “chips”, like peanut butter or white chocolate chips.
