How strong is the mint flavor in these brownies?

The mint flavor is subtle and balanced, designed to complement the rich chocolate without overpowering it. Be sure to follow the exact measurement for mint extract, as too much can result in a toothpaste-like taste. You can always add a touch more if you prefer a stronger mint presence, but start small.

Can I make these brownies ahead of time?

Yes! Triple Layer Fudgy Mint Oreo Brownies are actually better when made a day in advance. This allows the layers to set and the flavors to meld. Store them in an airtight container in the refrigerator for up to 10 days or freeze for up to 6 months.

What can I use if I can’t find Mint Oreos?

If Mint Oreos aren't available, you can use regular Oreos and add an extra drop or two of mint extract to the marshmallow mixture. Thin Mint cookies or similar chocolate-mint cookies can also work well in this recipe.

Can I use a boxed brownie mix instead of making them from scratch?

Absolutely. While homemade gives the best texture and flavor, a high-quality boxed brownie mix can be a great time-saving shortcut. Make the brownie layer according to box instructions, then continue with the mint and Oreo topping layers as written.

Instructions

Preheat oven to 350°F (175°C). Line a 9×13-inch pan with foil and spray with nonstick spray.
In a medium bowl, mix marshmallow fluff, mint extract, and green food coloring until light green. Set aside.
In a large microwave-safe bowl, melt the chocolate and butter together (about 90 seconds), then stir until smooth.
Stir in granulated sugar until combined (mixture will be grainy).
Add eggs and vanilla extract, then optional coffee, and mix well.
Fold in flour until just combined. Do not overmix.
Fold in 12 hand-crumbled Mint Oreos.
Pour batter into prepared pan. Drop 1/2 cup of the mint marshmallow mixture over the batter and swirl with a knife.
Bake for 23–25 minutes or until set. Cool completely (1 hour or chill for 10 minutes in freezer).
While cooling, prepare the frosting: Beat softened butter with powdered sugar, vanilla extract, and milk until fluffy.
Melt white chocolate chips in a microwave-safe bowl (30-second intervals).
Combine frosting, melted white chocolate, and remaining mint marshmallow mixture. Add more food coloring if needed.
Spread frosting over cooled brownies evenly.
Top with 18 hand-crumbled Mint Oreos, pressing gently into the frosting.
Chill until the top layer is firm before slicing and serving.

Notes

Do not add more mint extract than specified to avoid overpowering flavor.
Brownies are best chilled and can be stored in the fridge for up to 10 days or frozen for 6 months.
You can substitute store-bought brownie mix and frosting to save time.
Use regular Oreos if Mint Oreos are unavailable and add a bit more mint extract to the filling.
