It’s the most wonderful time of the year! Now that I’ve got you singing, picture these easy peppermint Oreo brownies made with a brownie mix. They are fudgy, dense, and taste reminiscent of Thin Mints Girl Scout cookies but better because they are brownies. You are absolutely going to want these on your Christmas dessert spread.

About these Easy Peppermint Oreo Brownies made with a Brownie Mix
I normally am not a big fan of chocolate and peppermint desserts, but these are an exception. The peppermint is not overpowering since this recipe does not contain peppermint extract. Aside from the amazing taste, I love these shortcut brownies because they are so easy.

When I say they are easy, they are so easy a three year old can make them! My son even cracked the eggs. These are also very budget friendly. I purchased the peppermint sandwich cookies at Aldi, but keep in mind they are seasonal and the Oreo brand or other store brand ingredients will work great too. Here are the ingredients we used:

Recipe FAQs
Absolutely! You don't even have to use the Oreo brand of chocolate sandwich cookies. Just note that the current mint Oreos have a green filling instead of white. I used the Aldi chocolate peppermint sandwich cookies in this recipe and they worked like a charm. You could also use regular Oreo cookies if you are not a fan of mint.
I have not tested this recipe with homemade brownies. You could certainly try it out, but I recommend the brownie mix because they consistently turn out perfectly fudgy and are inexpensive. Any brand of brownie mix will do.
I personally like to leave them whole because I like how they look when cut. The cookies will float somewhat to the top while baking. That is normal. However, you may coarsely chop them and mix them into the batter if you desire. The brownies will look differently when cut.
I hope you enjoy these peppermint oreo brownies. They are especially tasty while they are still warm, but you could also serve them with ice cream and hot fudge and crushed peppermints. That would really be a treat!
