Mint Oreo Cookie Brownie Bars Recipe

These Mint Oreo Cookie Brownie Bars are easy to make and the perfect combination of chocolate and mint. They are so easy to make, and the Oreo cookies are just the cherry on top.


Ever since I was young, I have loved anything that involved mint and chocolate.

Thank goodness holiday recipes use this combination in so many delicious ways. These brownies have a rich minty chocolate flavor with mint-marshmallow creme swirled in the brownies and mixed in the frosting.

They are nothing short of amazing. Bonus: they use a brownie mix. It doesn’t get any easier than this recipe.

If you are making them for guests or family, they will be impressed by these bad boys, no doubt. They come together quickly, and are full of chocolatey mint flavor, that you are going to love.

Also Oreo’s. Who doesn’t love a dessert full of Oreo’s?

if you love these mint oreo cookie brownie bars, be sure to try this favorite summer dessert – No Bake Eclair Cake. so delicious!

what could i use instead of the mint oreo’s?

I am a huge mint Oreo fan. Really just a mint and chocolate fan. However, I understand they aren’t for everyone. My husband is personally not crazy about the combination, because he thinks mint should only be found in gum or breath mints. Which I totally get.

So if you are looking to switch out the mint Oreo’s, and use a chocolate or vanilla frosting, instead of mint, here is what we recommend trying:

  • Regular Oreos (or really any of the other Oreo flavors. These would be delish with the cake batter Oreo’s).
  • Candy (It would be delicious with, Reese’s, Snickers, Twix, Milkyway, M & M’s, Butterfingers, Reese’s Pieces, Kit Kats, etc.)
  • Marshmallows
  • Toffee Bits
  • Pecans or another favorite nut.
  • Sprinkles

  1. Thanks for the recipe. Mine turned out great and didn't last very long.

    To the one poster whose were falling apart. I added another cup of the white chocolate chips and made my own icing a littler thicker than I normally would. That gives it a little more constancy and should fix any falling apart that might occur.
    • I googled egg substitute for you and here are a few things that popped up....
      You can substitute three tablespoons of mayonnaise for one egg in baking. The recipe I wanted to use called for two eggs, but I only had one. I subbed the mayo for the other egg, and the pumpkin muffins I baked were no different than usual. Or, you can mash half a banana with half teaspoon of baking powder.

      I have also heard of substituting 1 egg for 1 mashed banana.
