Instructions
- Prep the Pan:
- Line a nine by nine inch pan with parchment paper for easy removal later and preheat the oven to three hundred fifty degrees
- Mix and Bake Brownie Base:
- Prepare the brownie batter as directed on your box Combine in a large bowl and stir until almost blended then fold in finely chopped Oreos to distribute the cookie bits evenly throughout Pour the batter into your lined pan and smooth the top
- Bake:
- Bake according to the box instructions usually between twenty five to thirty minutes Check for doneness with a toothpick inserted near the edge It should come out with a few moist crumbs for that perfect fudgy center
- Cool and Prep for Frosting:
- When brownies are done remove from the oven and let cool for five minutes Pop the pan into the freezer to chill This helps the frosting spread more easily and prevents it from melting
- Make the Mint Frosting:
- In a medium bowl beat together softened cream cheese and butter until completely smooth Add peppermint extract and a few drops of green food coloring Blend until evenly colored then gradually beat in powdered sugar Mix until the frosting is light and creamy and holds its shape
- Frost the Brownies:
- Spread the mint frosting evenly over the cooled brownies using an offset spatula Place the pan back in the freezer to firm up the frosting
- Make Ganache:
- Pour chocolate chips into a heatproof bowl In a separate microwave safe bowl combine heavy cream and butter Heat in the microwave for sixty seconds Stir then pour the hot cream mixture over the chocolate chips Cover and let sit for five minutes
- Finish the Ganache:
- After five minutes whisk the mixture until smooth and glossy Let the ganache stand for ten to fifteen minutes so it thickens to a pourable consistency
- Top with Ganache:
- Pour the ganache over the mint frosting and use a spatula to gently spread it all the way to the edges Let the brownies sit at room temperature for thirty minutes so the ganache sets slightly
- Chill and Cut:
- Refrigerate the pan for two to three hours to fully set the layers for clean slicing Once chilled lift out using the parchment ends and cut into squares with a sharp warm knife
I am always amazed by how just a drop of peppermint creates a whole new craving for brownies The green mint frosting is my son’s favorite part but for me the velvety ganache is absolutely irresistible Every time we cut into these brownies at a party there is a little cheer
Storage Tips
Keep brownies in an airtight container in the fridge for up to five days The cool temperature helps the frosting and ganache stay firm For serving let them sit at room temperature for about fifteen minutes so the bite is soft but not messy If you want to freeze them slice and layer between parchment in a freezer safe box They keep well for up to two months and thaw overnight in the fridge
Ingredient Substitutions
Use gluten free brownie mix if needed and gluten free chocolate cookies in place of Oreos For a softer frosting swap mascarpone for cream cheese You can change the extract to orange or almond for a totally different twist and swap the chocolate chips for chopped baking chocolate if that’s what you have
Serving Suggestions
These brownies are stunning on a holiday dessert platter especially with sprinkles or extra crushed Oreos on top Cut small squares for rich party bites or pair with vanilla ice cream for an extra special treat Sometimes we serve them in mini paper cups at bake sales for easy grabbing
Cultural and Historical Context
Mint and chocolate have been paired for decades showing up in everything from grasshopper pies to classic after dinner mints These brownies are a playful nod to that nostalgic combo with a three layer twist The green color makes them particularly popular around Saint Patricks Day and at winter parties
Seasonal Adaptations
Use red food coloring for a festive holiday look in December Swap peppermint for lemon and a yellow tint in the spring Add fresh mint leaves on top for garden parties in the summer
