These Triple Layer Fudgy Mint Oreo Brownies are a chocolate lover’s dream with a minty twist! They’re loaded with rich, fudgy brownie layers, a creamy mint filling, and a crunchy Oreo cookie surprise all packed into one delicious treat. The combination of smooth chocolate and cool mint makes every bite feel like a little celebration.
I love making these brownies when I want a dessert that feels special but is still super easy to enjoy. The mint Oreo layer adds a fun crunch that I didn’t expect but can’t get enough of now. I also like to chill them for a bit before cutting so all the layers hold together just right—makes serving a breeze and keeps the edges clean.
These brownies are perfect for sharing at gatherings or just treating yourself after a long day. I’ve found that they disappear fast, maybe because everyone loves that minty chocolate mix. Whether you’re a mint fan or just a brownie fan looking for something a little different, these brownies always hit the spot for me!
Key Ingredients & Substitutions
Butter: Unsalted butter adds richness and helps make the brownies fudgy. If you want a dairy-free option, try coconut oil but the flavor will change slightly.
Granulated Sugar: This sweetens and gives the brownies a crisp top. You can use coconut sugar for a deeper flavor or reduce sugar slightly if you prefer less sweetness.
All-purpose Flour & Cocoa Powder: The flour gives structure, while unsweetened cocoa powder delivers that deep chocolate taste. Make sure to use cocoa powder, not chocolate chips, in the batter for best texture.
Mint Oreos: These give the mint flavor and crunch to the filling and topping. If you can’t find Mint Oreos, you can crush regular Oreos and add a few drops of peppermint extract to your mint cream layer.
Cream Cheese & Powdered Sugar: They create the creamy mint layer. You can swap cream cheese with mascarpone or a dairy-free cream cheese if needed. Powdered sugar helps keep the layer smooth and sweet.
How Do I Get Fudgy Brownies with These Layers?
Fudgy brownies come from the right balance of fat and flour, and careful mixing. Here’s what I do:
- Melt butter and mix with sugar off the heat so it cools slightly before adding eggs—this prevents scrambling.
- Mix in eggs one at a time, stirring well to fully combine for a smooth batter.
- Add dry ingredients gently—don’t overmix; this keeps brownies dense, not cakey.
- Fold in chopped chocolate for extra gooey spots inside.
- When layering, spread the batter evenly and don’t press too hard on the mint layer so the texture stays soft.
- Bake just until a toothpick comes out with a few moist crumbs to avoid drying out the layers.
Let the brownies cool completely and refrigerate before slicing to keep the layers firm and neat.
Equipment You’ll Need
- 9×9 inch baking pan – I like this size because it creates thick, fudgy brownies that are easy to cut.
- Parchment paper or non-stick spray – helps you lift the brownies out easily for clean cuts.
- Medium saucepan – perfect for melting butter and mixing the brownie batter smoothly.
- Mixing bowls – for preparing the cream cheese layer and mixing ingredients separately.
- Whisk or electric mixer – I use a whisk for quick mixing, but an electric mixer makes it easier for the creamy layer.
- Spoons or offset spatula – helps spread the layers evenly in the pan.
- Optional: Cooling rack – for cooling the brownies evenly after baking.
Flavor Variations & Add-Ins
- Swap Mint Oreos for Cookies & Cream Oreos to change the flavor and add extra crunch.
- Add chopped nuts (like pecans or walnuts) into the brownie batter for extra texture.
- Use white chocolate chips instead of semi-sweet for a sweeter, creamier flavor.
- Mix in a teaspoon of peppermint extract into the brownie batter for a stronger mint flavor without Oreos.

How Much Time Will You Need?
The total time for this recipe is about 15 minutes of prep and 35-40 minutes baking time. Plus, plan on at least 1 hour to chill the brownies after baking to get nice, clean layers when you cut them.
Step-by-Step Instructions:
1. Preheat Oven and Prepare the Pan:
Set your oven to 350°F (175°C) and line a 9×9 inch baking pan with parchment paper or lightly grease it. This helps you remove the brownies easily later.
2. Make the Brownie Batter:
Melt the butter in a medium saucepan over low heat. Remove from heat and whisk in the granulated sugar until well mixed. Add the eggs one at a time, mixing fully after each. Stir in vanilla extract.
3. Combine Dry Ingredients & Mix:
Sift together the flour, cocoa powder, salt, and baking powder in a bowl. Gradually add these dry ingredients into the wet mixture, stirring gently until just combined. Fold in the chopped chocolate or chips for extra gooey bites.
4. Prepare the Mint Cream Layer:
In a separate bowl, beat the softened cream cheese and butter until smooth. Add powdered sugar, peppermint extract, and green food coloring if using. Mix until creamy, then gently fold in the crushed Mint Oreos, keeping some chunky bits.
5. Assemble the Layers:
Spread half of the brownie batter evenly into the prepared pan. Carefully spoon and smooth the mint cream layer on top. Then gently spread the remaining brownie batter over the mint layer, ensuring an even layer.
6. Add Oreo Topping & Bake:
Place whole Mint Oreos evenly across the top, pressing them lightly into the batter. Bake the brownies for 35-40 minutes or until a toothpick near the center comes out with a few moist crumbs.
7. Cool, Chill & Serve:
Let the brownies cool completely in the pan on a wire rack. For best results, chill them in the refrigerator for at least 1 hour to set the layers firmly. Cut into squares, garnish with fresh mint leaves if you like, and enjoy!
Can I Use Regular Oreos Instead of Mint Oreos?
Yes, you can substitute regular Oreos if you don’t have mint-flavored ones. To keep the mint flavor, add a little peppermint extract to the cream cheese layer. This way, you still get that refreshing minty touch!
How Should I Store Leftover Brownies?
Store leftover brownies in an airtight container in the refrigerator for up to 4 days to keep the cream layer fresh. Before serving, bring them to room temperature for a softer texture or warm briefly in the microwave.
Can I Make These Brownies Ahead of Time?
Absolutely! These brownies actually taste better after chilling for a few hours or overnight, which helps the layers set perfectly. Just cover them tightly and keep refrigerated until ready to serve.
What If I Don’t Have Green Food Coloring?
Green food coloring is optional and just for a festive look. You can easily skip it without changing the flavor — the mint taste comes from the peppermint extract and Oreos, so your brownies will still be delicious.
