Why you’ll love m&m cookie bars
These cookie bars are a fun and colorful twist on the classic chocolate chip cookie. Rich with caramel flavor and studded with rainbow colored m&ms that burst with chocolate in every bite, these cookie bars are soft and chewy with crispy golden brown edges.
I’ve always loved this flavor combination in a cookie, and now it’s even easier to make as a bar- you can mix all the ingredients in just one bowl and bake them up in one 8 x 8 inch baking dish! So easy to make and even easier to clean up!
Recipe Tips for the best m&m cookie bars
Do not over bake them. The key to a soft and chewy cookie is to pull them out of the oven as soon as they puff up in the center and turn light golden brown around the edges. The same is true for cookie bars. This is not a secret, but it makes a HUGE difference in the texture of your cookie, and I think it also makes them last a little longer too!
Recipe Variations
Switch out the dark brown sugar for light brown sugar if you prefer a milder caramel flavor.
In addition to the m&ms try adding milk, semi-sweet, dark, or white chocolate chips to these bars to make them extra chocolatey and decadent.
