Jump to Recipe

These Chewy M&M Cookie Bars are the perfect dessert for kids (and adults too)! These bars are a little sweet, chewy, gooey and loaded with M&M’s! My kids had so much fun helping to make these.

How to make Chewy M&M Cookie Bars

This recipe is easy and does not require too many ingredients, most of which you probably have on hand! Scroll to the bottom for the full recipe. First, in the microwave or on the stove, melt the butter. Then, add in light brown sugar and stir well. Let cool for 5-10 minutes to avoid scrambling the eggs. Add eggs one at a time being sure to fully incorporate before adding the next. Add flour and baking powder; stir to combine. Mix in 1 cup of M&M’s. Pour batter into a greased or parchment lined 9 x 13″ baking pan. Spread into an even layer and top with remaining M&M’s. Bake at 350 degrees for 25-30 minutes or until toothpick inserted into the center comes out almost clean. These will still be gooey!

How to cut cookie bars

The worst thing after making a beautiful batch of bars or brownies is not being able to cut them!! Let them cool completely in the pan before slicing. If you used parchment paper to line the pan you will be able to pick up the bars out of the pan and slice them on a cutting board. I would highly recommend using parchment if you want perfectly cut bars. Slicing them in the pan is not as easy.

How to store or freeze cookie bars

Cookie bars will stay good at room temperature in an airtight container for about 5 days. If you want to freeze them, wrap them in plastic wrap then place in a zip lock bag or airtight container and freeze up to 3 months. Defrost at room temperature before eating.

    If you were to add chocolate chips to this, what amount would you recommend?

      You can just do a full swap for the M&M’s or if you want to do both 3/4 cup of each M&M’s and chocolate chips.
