M&M Cookie Bars are soft and chewy, buttery and rich loaded with chocolate chips and M&M’s.

These M&M cookie bars only take minutes to throw together, with no chilling time and you bake it all at once instead of in cookie batches like my M&M Cookie Recipe.

Tips for making M&M Cookie Bars:

I used regular M&M's but you can use peanut butter, Crispy, Pretzel, whatever your favorite is.
I always use a metal baking pan lined with parchment paper. For easy removal and clean-up. If you bake in a glass dish the baking time may be different.

The top should be slightly golden brown and the center should be baked through. I'm one that prefers to pull them from the oven at the 20 min mark. That way when they cool they are guaranteed to be soft and chewy.
