Triple Layer Fudgy Mint Oreo Brownies
Report
These Triple Layer Fudgy Mint Oreo Brownies feature a fudgy chocolate brownie base mixed with Cool Mint Oreos, topped with a mint-flavored marshmallow filling swirled into the batter, and finished with a white chocolate and Oreo frosting layer. The combination creates a rich, minty, and multi-textured dessert.
Description
The brownies begin with melted baking chocolate and butter combined with sugar, eggs, and optional espresso for depth. Flour is folded in along with hand-crumbled Cool Mint Oreos that add mint flavor and cookie crunch throughout. The batter goes into a foil-lined baking pan.
A separate mint marshmallow fluff mixture colored pale green and flavored delicately with mint extract is dolloped on top and gently swirled to create a marble effect. The brownies bake until set.
After baking, the top is frosted with a creamy white chocolate and butter frosting blended with vanilla and powdered sugar, then topped with additional crumbled Oreos for texture and garnish. These layered brownies offer moist fudgy cake pockets combined with sweet mint creaminess and cookie crunch.
The recipe allows substitutions such as using a boxed brownie mix, store-bought frosting, or more mint extract if desired. Mint Oreos are essential for authentic flavor.

Brownies
- 4 ounces baking chocolate used 9 squares of TJ’s 72% chocolate bar
- ¾ cup butter melted (1 1/2 sticks, unsalted
- 2 cups granulated sugar
- 3 egg
- 1 teaspoon vanilla extract
- 2 tablespoons espresso optional, or brewed coffee
- 1 cup all-purpose flour
- 12 Oreo cookies hand-crumbled, Cool Mint flavor
- Frosting and Topping
Frosting and Topping
- ½ cup butter softened, or margarine
- 3 to 4 cups powdered sugar
- 1 teaspoon vanilla extract
- milk if necessary for consistency, splash
- ¾ cup white chocolate chips melted
- 18 Oreo cookies hand-crumbled, Cool Mint flavor
Instructions
- Preheat oven to 350°F. Line a 9×13-inch pan with foil and spray it with cooking spray.
Filling:
- In medium bowl, stir together marshmallow fluff, mint extract* (be very careful and do not use more than this unless you love mint; a little bit of mint goes a very long way), 4 drops of food coloring, or until light green is achieved; set aside.
Brownies:
- Microwave chocolate and butter in large microwave-safe bowl for 90 seconds or until butter is melted. Stir until chocolate is completely melted.
- Stir in sugar (it will seem very granular, this is okay).
- Stir in eggs and vanilla. If adding espresso or coffee, add it now.
- Stir in flour until just combined, do not overmix.
- Hand-crumble 12 Oreos over the bowl and fold them in.
- Spread brownie batter in prepared pan.
- Drop about 1/2 cup of green filling mixture onto brownie batter and reserve the remainder. Gently pull a table knife through the batter in S-shaped curves for a swirled design.
- Bake 23 to 25 minutes or until brownies are set, taking care not to overbake. (Some people’s ovens and taste preferences may require 25-30 minutes, bake until brownies are done and to your liking).
- Cool completely, about 1 hour, or put the pan into the freezer for 10 minutes if you’re rushed.
Frosting and Topping:
- While brownies are cooling, make vanilla frosting by whisking together the butter, confectioners’ sugar, vanilla, and milk as needed until smooth and fluffy, or beat with an electric mixer. Optionally use 1 cup store-bought vanilla frosting – or use entire can if you want a thicker final green layer.
- In another small microwave-safe bowl, melt the white chocolate chips (microwave on high for 30 seconds; stir and microwave 30 seconds longer; stir until smooth, taking care not to scorch it as white chocolate scorches easily).
- Add the melted white chocolate chips and the vanilla frosting to the reserved green minty marshmallow mixture.
- Stir in 4 drops+ food coloring, or until light green color is reached, and spread over cooled brownies.
- Sprinkle with 18 hand-crumbled Oreo Cookies, slightly pressing them into the green mixture.
- Allow top layer to set fully before slicing and serving.
Notes
- If Mint Oreos are unavailable, increase mint extract in the filling slightly to maintain flavor.
- You may simplify by using your favorite boxed brownie mix and store-bought vanilla frosting instead of making from scratch.
- These brownies are rich and best enjoyed in moderation.
