Triple Layer Fudgy Mint Oreo Brownies are a chocolate lover’s dream with a cool twist. These brownies are packed with rich, fudgy chocolate layers, a refreshing mint cream filling, and crunchy Oreo cookies all stacked together for a perfect bite every time. The combination of smooth chocolate and cool mint flavors makes these brownies stand out.
I love making these brownies whenever I want a special treat that feels both classic and a little different. The mint layer adds a fun surprise that makes each bite exciting, and the Oreos bring a satisfying crunch that balances the softness of the brownie. I find that letting them cool completely before cutting helps keep those layers clean and beautiful.
These brownies are great for sharing at parties, bringing as a gift, or simply enjoying with a glass of milk on a cozy afternoon. Whenever I make them, they disappear fast because everyone loves the mix of chocolate and mint together. It’s a recipe I keep coming back to when I want something that tastes fancy but is actually super easy to put together.
Key Ingredients & Substitutions
Butter & Chocolate: Melted butter and semi-sweet chocolate create that rich fudgy base. If you prefer dairy-free, try coconut oil and dairy-free chocolate chips.
Cream Cheese: This gives the mint layer its smooth, creamy texture. You can swap it for mascarpone or a vegan cream cheese if needed.
Peppermint Extract: Use this for mint flavor. If you can’t find peppermint extract, try spearmint or add a small amount of mint syrup, but adjust sweetness.
Mint Oreo Cookies: These add crunch and classic mint-chocolate taste. If unavailable, use regular Oreos with a drop of peppermint extract mixed into the cream layer.
Green Food Coloring: Makes the mint layer visually fun but optional if you prefer natural mint flavor without color.
How Do You Get a Fudgy Brownie Base That Layers Well?
Achieving a fudgy, yet sturdy brownie base is key because it holds the layers without crumbling. Here’s how:
- Use melted butter and chocolate for dense, fudgy texture.
- Don’t overmix the batter; fold just until combined to keep it tender.
- Bake only until the edges set and the center looks slightly underbaked—this keeps it moist and chewy.
- Let the brownie cool somewhat before adding the cream layer so the mint layer doesn’t melt or mix in.
Patience is important here! Cooling helps the layers stay distinct and makes cutting easier.
Equipment You’ll Need
- 9×13-inch baking pan – I like using this size because it fits all the layers perfectly.
- Parchment paper or foil – makes it easy to lift out the entire block for clean cutting.
- Medium saucepan – for melting butter and chocolate smoothly.
- Mixing bowls – for preparing the cream cheese layer and mixing ingredients.
- Hand or stand mixer – helps beat the cream cheese and whip the mint layer evenly.
- Spatula – for spreading the layers smoothly and gently.
- Cooling rack – to let the brownies cool evenly before cutting.
Flavor Variations & Add-Ins
- Swap peppermint extract for almond or vanilla extract for a different flavor twist.
- Add chopped walnuts, pecans, or coconut flakes into the brownie batter for extra texture.
- Use dark chocolate or white chocolate instead of semi-sweet for a different chocoholic experience.
- Mix in crushed candy canes or peppermint candies into the mint layer for more minty crunch.

How Much Time Will You Need?
This recipe takes about 20 minutes to prep, 45-50 minutes to bake in two stages, plus 1-2 hours of chilling time for setting. Plan for about 3 hours total from start to ready-to-serve.
Step-by-Step Instructions:
1. Prepare the Pan and Brownie Base:
Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper or foil, leaving some extra hanging over the sides for easy lifting later. In a medium saucepan over low heat, melt the butter and chopped semi-sweet chocolate, stirring until smooth. Take the pan off the heat and let it cool a bit.
2. Mix Brownie Batter:
Whisk both sugars into the melted chocolate mixture until combined. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract. In a separate bowl, sift together the flour, cocoa powder, and salt. Fold the dry ingredients gently into the wet until just combined—don’t overmix.
3. Bake the First Brownie Layer:
Pour half the brownie batter evenly into your lined pan. Bake for 15-20 minutes until it’s set but still slightly soft. Remove it from the oven and let cool slightly.
4. Make the Mint Cream Layer:
In a large bowl, beat the softened cream cheese and sugar until smooth and creamy. Stir in peppermint extract and green food coloring, mixing until evenly colored. If you’d like, gently fold in crushed mint Oreos or chopped mint candies for extra texture.
5. Assemble Layers:
Spread the mint cream layer evenly over the warm brownie base. Arrange whole Mint Oreo cookies evenly on top of this layer.
6. Add Top Brownie Layer and Bake:
Carefully pour the remaining brownie batter over the Oreos and mint layer, spreading gently to cover without disturbing the layers below. Sprinkle mini chocolate chips or chopped chocolate on top. Bake again for about 25-30 minutes, until a toothpick inserted in the brownie layer comes out with moist crumbs but no wet batter.
7. Cool, Chill, and Serve:
Take the pan out of the oven and let it cool completely on a wire rack. Chill in the fridge for 1-2 hours to help the layers set firmly. Use the parchment or foil edges to lift the brownies from the pan, cut into squares, and enjoy!
8. Storage Tips:
Keep leftovers in an airtight container in the fridge for up to 4 days. These brownies taste great chilled or at room temperature.
Can I Use Frozen Cream Cheese for the Mint Layer?
It’s best to use softened cream cheese for a smooth mint layer. If your cream cheese is frozen, thaw it in the fridge overnight and bring it to room temperature before mixing to avoid lumps.
What Can I Substitute for Mint Oreo Cookies?
If you can’t find Mint Oreos, try regular Oreos with added peppermint extract in the cream layer, or use crushed peppermint candies for that refreshing minty crunch.
How Should I Store Leftover Brownies?
Store the brownies in an airtight container in the refrigerator for up to 4 days. Let them come to room temperature or enjoy chilled for a firmer texture.
Can I Make These Brownies Ahead of Time?
Absolutely! Prepare the brownies a day ahead and refrigerate overnight. This helps the layers set perfectly and enhances the flavors.
