These Triple Layer Fudgy Mint Oreo Brownies are a chocolate lover’s dream with an extra minty twist. They’re packed with rich, fudgy brownie layers, a creamy mint filling, and a crunchy Oreo cookie surprise right in the middle. If you like the combo of mint and chocolate, these brownies have it all wrapped up in one delicious treat.
I love making these when I want something that feels special but isn’t too tricky to whip up. The way the Oreo cookies add a little crunch between the soft brownie layers is my favorite part—plus that cool mint flavor brightens every bite. I usually chill them a bit before cutting so the layers hold together nicely and it’s easier to enjoy each fudgy bite.
These brownies are perfect for sharing at a party or just enjoying at home with a cold glass of milk or a cup of coffee. Whenever I bring a batch to friends or family, they always ask for the recipe. It’s like a little chocolate and mint treat that makes any day feel a bit more fun and special.
Key Ingredients & Substitutions
Unsalted Butter: This is important for that rich, fudgy texture. You can swap with margarine or coconut oil, but butter gives the best flavor and moistness.
Mint-flavored Oreos: These add that cool mint crunch. If you can’t find mint Oreos, use regular Oreos plus a bit more peppermint extract in the filling for mint flavor.
Cream Cheese: Gives the mint layer a smooth, creamy texture. For a lighter option, try mascarpone or even Greek yogurt mixed with powdered sugar, though texture will differ.
Peppermint Extract: Use just a small amount; it’s strong! You can substitute with mint extract, but start with less to avoid overpowering the brownie.
Cocoa Powder & Chocolate Chips: The heart of the brownie base. Unsweetened cocoa powder brings deep chocolate flavor. Use semi-sweet chocolate chips or switch to dark or milk depending on your taste.
How Do I Get That Perfect Fudgy Brownie Texture?
The secret to fudgy brownies is balancing the wet and dry ingredients and not overbaking.
- Melt the butter gently and mix with sugar before eggs; this helps dissolve sugar for smooth batter.
- Add eggs one at a time and mix well, for structure and moisture.
- Don’t overmix once you add flour — just combine to avoid tough brownies.
- Bake at a moderate temperature (350°F) and check for doneness around 35 minutes. The toothpick should come out with moist crumbs, not clean.
- Let brownies cool fully and chill for cleaner cuts and better layer setting.
Equipment You’ll Need
- 9×13 inch baking pan – I like this size because it gives enough room for layers without being too thick.
- Parchment paper or non-stick spray – helps with easy removal and clean-up.
- Medium saucepan – for melting the butter and mixing the brownie batter.
- Mixing bowls – for the cream cheese filling and whipping the cream.
- Hand or stand mixer – makes whipping the cream and mixing the filling easier.
- Spatula or spoon – for spreading the batter and filling evenly.
Flavor Variations & Add-Ins
- Use caramel or white chocolate chips instead of semi-sweet for a different sweet twist.
- Add chopped nuts like pistachios or walnuts inside the brownie layer for extra crunch.
- Include a drizzle of caramel or chocolate sauce on top before baking for extra gooeyness.
- Swap mint Oreos with peanut butter Oreos and add a dollop of peanut butter to the cream filling for a nutty flavor.

Time Needed

Step-by-Step Instructions:
1. Prepare the Brownie Base
Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper or grease it well so the brownies don’t stick.
2. Make the Brownie Batter
In a medium saucepan, melt the butter gently over low heat. Remove from heat and stir in the granulated sugar until smooth. Add the eggs one at a time, whisking well after each. Stir in the cocoa powder, salt, baking powder, and vanilla extract until smooth and well combined.
3. Add Flour and Chocolate Chips
Slowly add the flour and mix until just combined – don’t overmix. Fold in the chocolate chips gently with a spatula.
4. Layer the Bottom Brownie Batter
Spread half of the brownie batter evenly into your prepared pan, smoothing the top.
5. Add the Oreo Layer
Place a layer of Oreo cookies evenly over the brownie batter in the pan. This yummy layer adds crunch and minty flavor!
6. Prepare the Mint Cream Filling
In a medium bowl, beat the softened cream cheese until smooth. Add the powdered sugar and peppermint extract and whip together. In a separate bowl, whip the heavy cream until stiff peaks form, then gently fold it into the cream cheese mixture. Add a few drops of green food coloring for a lovely minty color if you like.
7. Add the Mint Cream Layer
Spread the mint cream filling evenly over the Oreo cookies, creating the second layer.
8. Top with Remaining Brownie Batter
Dollop and spread the remaining brownie batter gently over the mint cream. It’s okay if it looks a little uneven – it will bake perfectly.
9. Optional Toppings
You can press a few Oreo cookies on top and sprinkle extra chocolate chips for a pretty finish.
10. Bake Your Brownies
Bake in the preheated oven for 35 to 40 minutes. Check doneness by inserting a toothpick near the center; it should come out with moist crumbs, not clean. Avoid overbaking to keep the brownies fudgy.
11. Cool and Chill
Remove the pan from the oven and let cool completely. Refrigerate for 1 to 2 hours to help the layers set and make slicing easier.
12. Serve and Enjoy
Garnish with fresh mint leaves if you like, then cut into squares. Serve and enjoy these rich, fudgy, minty, and chocolatey brownies!
Can I Use Regular Oreos Instead of Mint Oreos?
Yes, you can! Just add a little extra peppermint extract to the mint cream filling to keep that refreshing mint flavor.
How Should I Store These Brownies?
Store leftovers in an airtight container in the fridge for up to 4 days. The cream layer keeps best when chilled.
Can I Make These Brownies Ahead of Time?
Absolutely! You can prepare and bake them a day ahead, then refrigerate overnight. Just slice and serve when ready.
Can I Freeze the Brownies?
Yes, freeze fully cooled brownies in an airtight container or wrap tightly in plastic wrap for up to 3 months. Thaw in the fridge before slicing.
