Ingredients
- Brownie Mix: A convenient boxed mix that forms the fudgy brownie base, requiring eggs, oil, and water for preparation.
- Salted Butter (3/4 cup): Softened butter that adds richness to the mint buttercream layer with a subtle salty tang.
- Powdered Sugar (2 cups): Finely ground sugar providing sweetness and structure to the creamy mint frosting.
- Mint Extract (1 teaspoon): Fresh, concentrated mint flavor that brightens the buttercream without overpowering the chocolate.
- Green Food Coloring (1-2 drops): Adds a festive green hue to the mint frosting, enhancing its visual appeal.
- Heavy Whipping Cream (1-2 tablespoons): Used in the frosting to create a smooth, fluffy, and spreadable buttercream texture.
- Semi-Sweet Chocolate Chips (2 cups): High-quality chocolate chips melted to form a silky chocolate ganache topping.
- Heavy Whipping Cream (1 cup): Heated and combined with chocolate chips to create the rich ganache layer.
Instructions
- Preheat Oven and Prepare Pan
Set your oven to the temperature specified on the brownie box. Line an 8×8 inch baking pan with parchment paper to prevent sticking and ensure easy removal after baking.
- Mix and Bake Brownies
Prepare the brownie batter according to the package instructions by combining the mix with eggs, oil, and water. Pour into the parchment-lined pan evenly. Bake until a toothpick inserted comes out with moist crumbs, then allow brownies to cool completely to room temperature. Cooling is essential to avoid melting the buttercream in the next step.
- Make the Mint Buttercream
Beat the softened butter until creamy to create a smooth base. Gradually add powdered sugar and continue beating until combined, resulting in a dry mixture. Incorporate the mint extract for flavor and green food coloring for a festive look. Add heavy cream slowly to achieve a fluffy, spreadable consistency; adjust tint or flavor as desired.
- Spread Buttercream Layer
Using an offset spatula, gently spread the mint buttercream evenly over the completely cooled brownies. Refrigerate or freeze briefly to allow the frosting to firm up, creating a stable layer for the ganache topping.
- Prepare the Chocolate Ganache
Heat the heavy cream until steaming but not boiling. Pour it over the semi-sweet chocolate chips and cover with a plate to let the chocolate soften. After 3 to 4 minutes, whisk until smooth and glossy, ensuring a rich ganache with impeccable texture.
- Top Brownies with Ganache
Pour the ganache evenly over the chilled buttercream layer and spread gently to cover. Let the ganache set by leaving it at room temperature for 45 to 60 minutes or refrigerate for about 15 minutes until firm but still silky.
- Slice and Serve
Lift the brownies out using the parchment paper flaps for easy handling. Cut into 16 even squares with a sharp knife for tidy servings. Serve fresh and enjoy the decadent layers and mint-chocolate harmony.
- Allow brownies to cool fully before frosting to prevent buttercream from melting.
- Adjust mint extract carefully to avoid overpowering the chocolate flavor.
- Ganache can be prepared ahead and gently reheated for easier spreading if needed.
Storage Tips
Store mint brownies in an airtight container in the refrigerator for up to 5 days to maintain freshness and prevent the buttercream from softening. For longer storage, freeze brownies tightly wrapped for up to 3 months and thaw before serving.
Serving Suggestions
Serve mint brownies chilled or at room temperature with a glass of cold milk or a cup of hot coffee or tea. Garnish with fresh mint leaves or a sprinkle of crushed peppermint candies for festive occasions.
- Use high-quality chocolate chips for the ganache to achieve a smoother, richer topping.
- Green food coloring is optional but adds a beautiful vibrant touch that enhances the mint theme visually.
- For an extra layer of texture, consider adding chopped mint chocolate candies between the buttercream and ganache.
FAQs
- Can I make these brownies from scratch instead of using a boxed mix?

- Can I use peppermint extract instead of mint extract?
Peppermint extract is stronger and more intense; use less to avoid overpowering the buttercream’s flavor.
- How do I keep the buttercream from melting?
Ensure brownies are completely cooled and refrigerate the frosted brownies before adding the ganache to help set the layers.
- Can I make the ganache in advance?
Yes, ganache can be made up to 2 days ahead and stored chilled; gently warm to spread before using.
- What is the best way to cut the brownies?
Use a sharp knife cleaned between cuts for clean, even squares without smudging the frosting.
