Mint M&M Cookie Bars

Mint M&Ms and mini chocolate chips collide in gooey, chewy Mint M&M cookie bars. They are kiddo favorite, an adult favorite and perfect for holiday cookie tins.

A gooey, chewy cookie bar recipe is always a good thing to have on hand. They are quick, easy to make, versatile and always a crowd pleaser. 

All you need is a basic cookie dough recipe, in this case chocolate chip,  some of your favorite mix-ins and voila! Cookie bars! Easy right? Right. Let’s get to it. 

What ingredients do you need?

All of the usual cookie ingredients are here: flour, butter, brown and granulated sugar, eggs, vanilla, baking soda and salt. 

For the mix-ins, I wanted to pick something festive AND wanted to ensure that there was tons of chocolate mixed throughout. That is why for these M&M cookie bars, the mix-ins are Mint M&Ms and mini chocolate chips. 

These are called “mix-ins” but,  I also recommend throwing even more on top because, why not?

Step by Step Photos and Instructions: 

Step #1:  Beat together butter, brown sugar and granulated sugar until fluffy. About 2 minutes. 

Step #2: Beat in eggs and vanilla.

Step #3: Beat in flour, baking soda and salt. Continue beating until cookie dough comes together. 

Step #4: Fold in 1 cup each mint M&Ms and mini chocolate chips.  

Step #5. Top with more M&Ms and chocolate chips. Bake at 325 for 30 – 40 minutes or until golden brown. Cool completely before cutting. 

DES’ TIP: If you want these a bit chewier, under bake them ever so slightly. 

I know it’ll be hard, but it is really best to wait until the cookie bars  are completely cool before cutting. They will cut better and cleaner that way. 

Now that you know the basics of making a cookie  bar, you can use any mix-ins that you like. Different candy pieces. Different chocolate chips. You name it! But for Christmas these Mint M&M Cookie Bars really hit the spot!
