I LOVE M&M cookies, but I also love a dessert that comes together in one bowl, takes five minutes to whip up, and doesn’t require me babysitting the oven while swapping out cookie sheets. M&M cookie bars have entered the chat!

These M&M Cookie bars are soft, chewy, and filled with M&Ms and mini chocolate chips (optional, but highly suggested)! They’re inspired by the classic M&M cookie which is always a favorite – you can find my M&M Cookie Recipe here!

Storing M&M Cookie Bars

These cookie bars bake in an 8×8 pan that you can cover with foil to save for later, or cut cookie bars and store in an airtight container or bag for several days *but they won’t last that long! You can freeze these cookie bars after baking if you want to save for later!

Why you’ll love these M&M Cookie Bars

• No chilling, no mixer needed, no rolling cookies – this dessert is super easy to whip up!
• You can swap out the M&Ms to match seasonal colors. Who doesn’t love a fun seasonal dessert?
• You can easily double this recipe to make a larger pan to feed a crowd – perfect for family BBQs, birthday parties, and more!
• These are easily customized by topping with sprinkles, icing, different color M&Ms, etc!

Success Tips for the Best Results
