M&M Cookie Bars
These M&M Cookie Bars are so easy to make and absolutely delicious. Golden brown and delicious, they are packed with colorful M&M’S and mini chocolate chips. I just love the crunch of the M&M’S in this recipe! Make sure to add more M&M’S and mini chocolate chips to the top of the cookie dough before baking for a pretty presentation. No scooping or chilling the dough, these bake up in a snap and are perfect for parties or a crowd. This recipe bakes a full 9×13 pan of cookie bars, I’ve listed 18 as the recipe yield, but you can cut them smaller to serve more if you prefer.
How to Make M&M Cookie Bars
- Start by mixing the cookie dough. The dough should be fairly thick, so a stand mixer is best, but you can also use a hand mixer.
- Beat together two sticks of room temperature butter with brown sugar and granulated sugar.
- Add in eggs and vanilla extract and continue mixing until well combined.
- Add flour, salt, and baking soda and mix just until cookie dough forms.
- Finally, stir in chocolate chips and M&M’S.
- Transfer cookie dough to a 9×13 pan lined with foil and sprayed with nonstick cooking spray. This makes the bars easier to lift out and cut after baking.
- Sprinkle dough with additional M&M’s and mini chocolate chips.
- Bake 30-35 minutes in a 350 degree oven until bars are golden brown.
- Let cool completely and cut.
