These Triple Layer Fudgy Mint Oreo Brownies are a chocolate lover’s dream come true. Imagine rich, gooey brownie layers packed with chunks of Oreo cookies, all mingled with a refreshing hint of mint that makes every bite exciting. The combination of fudgy chocolate, creamy mint, and crunchy Oreos creates a really fun texture that’s hard to resist.
I love making these brownies when I want to treat myself or impress friends without spending hours in the kitchen. The mint gives such a bright, cool note that balances the dense chocolate perfectly. One tip I have is to use good quality cocoa powder and fresh Oreos to really bring out those flavors. I always find that a little sprinkle of sea salt on top before baking adds just the right touch of contrast.
These brownies are great served warm, maybe with a scoop of vanilla ice cream or just on their own with a glass of milk. They’re perfect for holiday parties, casual get-togethers, or anytime you crave that classic chocolate-and-mint combo with an extra fun Oreo twist. I always end up making a double batch because everyone wants seconds!
Key Ingredients & Substitutions
Unsalted Butter: Butter adds rich flavor and helps create that fudgy texture. If dairy-free, use a plant-based butter or coconut oil for a similar effect.
Oreos: Classic Oreos give crunch and mint filling. You can swap them for any chocolate sandwich cookie, but mint flavor is key here to keep the fresh twist.
Peppermint Extract: This boosts the minty flavor. If you don’t have it, a few drops of pure mint oil or finely chopped fresh mint leaves can work but adjust quantity carefully to avoid overpowering.
Cream Cheese & Heavy Cream: These create the smooth, fluffy mint layer. For a lighter option, try mascarpone cheese or whipped coconut cream.
Cocoa Powder & Chocolate Chips: Use good quality cocoa for deep chocolate flavor. Dark or semi-sweet chips melt nicely for the top layer; you can swap with milk chocolate for a sweeter finish.
How Can I Get the Perfect Fudgy Texture in My Brownies?
Fudgy texture is all about balancing ingredients and baking time. Here’s what helps:
- Melt the butter and whisk sugar in while still warm to help dissolve sugar and add moisture.
- Avoid overmixing once you add flour and cocoa; stir just until combined to keep brownies tender.
- Bake at 350°F (175°C) for about 25-30 minutes. Check with a toothpick—it should come out with moist crumbs, not dry.
- Let the brownies cool completely before adding layers or cutting, so they hold their shape and stay moist.
Following these tips will give you dense, rich brownies that are soft and chewy inside—just what you want for a fudgy delight.

Equipment You’ll Need
- 9×13-inch Baking Pan – I recommend this size to make sure your brownies are thick and fudgy. Lining it with parchment makes for easy removal.
- Mixing Bowls – You’ll need a couple to mix the brownie batter and the mint cream layer; I like glass or metal bowls because they’re sturdy.
- Whisk and Rubber Spatula – For mixing ingredients smoothly and gently folding in Oreos without breaking them.
- Medium Saucepan – Used to melt butter and chocolate, making your prep easier and quicker.
- Electric Hand Mixer or Stand Mixer (optional) – Great for whipping the cream cheese and heavy cream to a fluffy consistency.
- Cooling Rack – To cool the brownies completely so layers set nicely before assembling.
Flavor Variations & Add-Ins
- Swap the Mint: Use caramel or peanut butter for a different twist. Caramel adds richness, while peanut butter offers a nutty flavor.
- Extra Crunch: Mix chopped nuts like walnuts or almonds into the brownie batter for added texture and flavor.
- Different Cookies: Use chocolate chip cookies or Nutter Butters instead of Oreos for variety, especially if you want to skip the mint.
- Chocolate Drizzle: Add a drizzle of white or milk chocolate over the top for extra sweetness and visual appeal.

- 1 cup (2 sticks) unsalted butter
- 2 cups granulated sugar
- 4 large eggs
- 1 teaspoon pure vanilla extract
- 1 cup all-purpose flour
- 1 cup unsweetened cocoa powder
- 1/2 teaspoon salt

How Much Time Will You Need?
This recipe takes about 15 minutes to prepare, 25-30 minutes to bake, and at least 2 hours to chill for the layers to set properly. So overall, plan for about 3 hours including cooling and chilling time.
Step-by-Step Instructions:
1. Prepare the Brownie Base:
Start by preheating your oven to 350°F (175°C). Grease a 9×13-inch baking pan or line it with parchment paper to make removal easier. In a medium saucepan over low heat, melt the butter. Take it off the heat and whisk in the granulated sugar while the butter is still warm. Add eggs one at a time, beating well after each addition, then stir in the vanilla extract. In another bowl, sift together the flour, cocoa powder, salt, and baking powder. Gradually add these dry ingredients to the wet mixture, stirring just until combined—try not to overmix.
2. Add Oreo Pieces into the Batter:
Chop 12 of the Oreo cookies roughly into chunks and gently fold them into the brownie batter. This adds delightful bits of crunch and flavor throughout.
3. Bake the Brownies:
Pour the batter evenly into the prepared pan, smoothing the top carefully. Bake for 25 to 30 minutes, or until a toothpick inserted near the center comes out with a few moist crumbs attached. Removing the brownies too late will make them dry, so start checking at 25 minutes. When done, allow the brownies to cool completely right in the pan.
4. Make the Mint Cream Layer:
In a clean mixing bowl, beat the cream cheese until smooth and creamy. Gradually add the powdered sugar. Slowly add the heavy cream and peppermint extract, beating continuously until the mixture becomes fluffy and spreadable. Gently fold in 4 crushed Oreo cookies to give extra texture and flavor.
5. Assemble the Layers:
Once the brownie base is fully cooled, spread the mint cream layer evenly across the top. Melt the chocolate chips in short bursts in the microwave or over a double boiler and drizzle or sprinkle the melted chocolate evenly over the mint layer. Press the whole reserved Oreo cookies lightly on top. Garnish with fresh mint leaves if you like.
6. Chill and Serve:
Place the assembled brownies in the refrigerator for at least 2 hours so the layers set firm. When ready, cut into squares using a sharp knife, wiping the blade clean between cuts for neat pieces. Serve chilled or at room temperature and enjoy this irresistibly rich, minty, and chocolaty treat!
Can I Use Frozen Oreos for This Recipe?
Yes, you can use frozen Oreos, but make sure to thaw them completely before chopping or folding into the batter. This prevents excess moisture that could affect the brownie texture.
How Should I Store Leftover Brownies?
Store leftover brownies in an airtight container in the fridge for up to 4 days to keep the mint cream layer fresh. You can also freeze them for up to 2 months; thaw in the fridge overnight before serving.
Can I Make This Recipe Dairy-Free?
Absolutely! Substitute the butter with a plant-based alternative, use dairy-free cream cheese, and replace heavy cream with coconut cream. Keep the peppermint extract and Oreos if they fit your dietary needs.
Can I Make These Brownies Ahead of Time?
Yes! Prepare the brownies and mint cream layer a day ahead, assemble, and refrigerate overnight. This actually enhances the flavors and makes slicing easier.
