M&M Oreo Cookie Bars

If you have a craving for Oreos, I have the perfect dessert recipe for you. Loaded M&M Oreo Cookie Bars are easy to make and they are so delicious that everyone who tries one will ask for a second!

Oreos are a classic treat that in my opinion qualifies as comfort food. They are yummy on their own, dunked in milk, or better yet, covered in chocolate! My Loaded M&M Oreo Cookie Bars recipe takes all of the flavour of Oreo cookies and makes them even better in the form of a cookie bar with all the fixings.

This Loaded M&M Oreo Cookie Bar recipe includes golden and regular Oreos and M&M’s for a total chocolatey treat! You will be glad the recipe makes 24 servings because these are perfect for sharing! These cookie bars make me believe in love at first bite. I have a feeling you will love them as much as I do!

The recipe creates a chewy bar cookie that is reminiscent of brownies, it has a soft dough but so many crunchy goodies inside that set this recipe off with a texture that is nothing short of craveable. I used milk chocolate M&M Minis in my Oreo Cookie Bars, but I have used peppermint M&M’s and peppermint bark Oreo cookies at Christmas time.
