Ingredients Needed
- Fudge Brownies Mix. I am a fan of the Betty Crocker extra fudgy brownie mix. You will also need all the ingredients called for on back of box. Usually includes eggs, water and oil.
- Marshmallow creme, one jar
- Mint extract
- Green food color
- Mint baking chips or white chocolate chips or milk chocolate chips.
- Mint creme filled chocolate sandwich cookies, you want to chop them.
- Butter. I use salted butter
- Powdered sugar
- Milk. Use whatever milk you have on hand, can also use heavy whipping cream or half and half.
How to Make Mint Oreo Brownies
- Mix up the brownie mix according to the directions on the back of the box in a bowl.
- Line a 9 x 13 inch pan with parchment paper to make it easier to remove and cut the brownies. You can also spray it with non stick baking spray if not using parchment paper.
- Pour brownie batter into prepared pan.
- Mix together marshmallow cream, 1/4 tsp mint extract and 4-5 drops of green food coloring.
- Drop the marshmallow mixture onto the top of the brownies in 6 even scoops.
- Swirl. Take a knife and swirl the marshmallow mixture through the brownie layer, using an S shape motion.
- Bake in a 350 degrees F oven for 25 minutes or until a toothpick comes out clean. After the brownies have baked and cooled they are ready to frost with a combination of yummy buttercream.
- Frosting. While the brownies are baking, mix up your frosting. If you can’t find mint chocolate chips, use white chocolate chips. Melt the chocolate in the microwave and cool slightly. Add into frosting. Add mint extract to taste and food coloring.
- Chop the Oreos with knife.
- Cool brownies. Once the brownies have cooled, frost and top with a layer of mint oreo cookies broken into pieces.
These Mint Oreo Brownies are pure mint decadence. Enough green to make any Leprechaun proud and keep you from getting pinched and a great way to get more green into your diet!
Tips from leigh Anne
- If you prefer, you can use your favorite homemade brownie recipe instead of a boxed brownie mix. I find that a fudgy brownie recipe works better than a more cake like recipe.
- If you aren’t a mint fan you can make a non mint version by using vanilla extract instead of mint extract, add in milk chocolate or white chocolate chips and use regular Oreos on top instead of mint Oreos.
- If you don’t have a microwave to melt the chocolate, you can use a double broiler on your stove top.
Frequently Asked Questions
How do you store leftover mint oreo brownies?
Keep any leftover brownies stored in an airtight container at room temperature for 3-4 days. They can also be kept in the refrigerator for 4-5 days
Is peppermint extract the same thing as mint extract?
No, it is not. It has a different flavor. You can use peppermint extract for this recipe if you want, but the mint flavor of the cookies will be different. You might be able to find a peppermint flavored sandwich cookie to use, especially at the holidays.
Can I freeze mint oreo brownies?
Absolutely! Just place them in an airtight container and they will last in the freezer for up to 3 months. Thaw in the fridge overnight or on the counter for an hour or so. You can rewarm them in the microwave for a few seconds if you want them warm and gooey.
