Ingredients You’ll Need

• ¾ cup (1 ½ sticks / 170 g) unsalted butter, melted, slightly cooled: Adds richness and moisture to the brownies. You can substitute with coconut oil for a dairy-free option.
• 1 ½ cups (300 g) granulated sugar: Sweetens the brownies while contributing to their fudgy texture. Brown sugar can also be used for a deeper flavor.
• 3 large eggs, room temperature: Essential for binding and providing structure. Make sure they’re room temperature to ensure even mixing.
• 2 teaspoons vanilla extract: Enhances the flavor profile of the brownies. Use pure vanilla for the best taste.
• ¾ cup (94 g) all-purpose flour: Gives the brownies structure. For gluten-free options, try almond flour or a gluten-free flour blend.
• ½ cup (50 g) unsweetened cocoa powder: For that intense chocolate flavor. Use Dutch-processed cocoa for a richer taste.
• ¼ teaspoon kosher salt: Balances the sweetness and heightens the chocolate flavor.
• ¼ teaspoon baking powder: Helps the brownies rise slightly, though we’re aiming for a dense, fudgy texture.
• 3 cups (375 g) confectioners’ sugar: Used to make the creamy mint filling. This gives it a sweet, smooth texture.
• ¾ cup (1 ½ sticks / 170 g) unsalted butter, softened: Helps create a creamy mint filling. You may substitute with vegan butter for a dairy-free option.
• 1 teaspoon peppermint extract: Provides that refreshing mint flavor. Adjust to your taste preference if you like it more minty.
• 3 drops green food coloring: For a fun, festive look! Feel free to adjust based on how vibrant you want it.
• 2 tablespoons whole milk or heavy cream: Adds richness to the mint filling. You can use almond milk for a dairy-free version.
• 12 ounces (340 g) semi-sweet chocolate chips or chopped chocolate: For the ganache. Dark chocolate works well too, providing a rich finish.
• 8 tablespoons unsalted butter, diced into tablespoons: Contributes to the silky smooth ganache.

How to Make Fudgy Chocolate Mint Brownies

1. Prepare the Baking Pan: Preheat your oven to 350°F (177°C). Line a 9×13-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal. Lightly spray the parchment with nonstick cooking spray.
2. Mix Brownie Batter: In a large bowl, whisk together the melted butter and granulated sugar until well combined. You’ll know it’s ready when it’s glossy. Add the room temperature eggs and vanilla extract, mixing until smooth.
3. Combine Dry Ingredients: Gently fold in the all-purpose flour, cocoa powder, kosher salt, and baking powder. Be careful not to overmix; a few lumps are fine.
4. Bake the Brownies: Spread the batter evenly into the prepared pan and bake for 25 to 30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. Let the brownies cool completely in the pan on a wire rack, about 1 hour.
5. Prepare the Mint Filling: In a medium bowl, beat the confectioners’ sugar, softened butter, peppermint extract, green food coloring, and 2 tablespoons of milk together with an electric mixer until smooth and spreadable. Add another tablespoon of milk if needed to reach your desired consistency.
6. Spread the Mint Layer: Once the brownies have cooled, spread the mint filling evenly over the top using an offset spatula. Refrigerate for 15 to 30 minutes, or until the mint layer is firm.
7. Make the Ganache: In a microwave-safe bowl, combine the chocolate chips and diced butter. Microwave in 20 to 30 second intervals, stirring after each until the mixture is glossy and mostly melted. Stir until completely smooth, taking care not to overheat it.
8. Finish the Brownies: Let the ganache cool slightly for about 5 to 10 minutes before pouring over the chilled mint layer. Spread it into an even layer.
9. Chill and Serve: Refrigerate the brownies for at least 1 to 2 hours, or until the ganache is fully set. If you want the cleanest slices, chill overnight. Use the parchment overhang to lift the brownies out of the pan, then cut into neat squares.

Storing & Reheating

To store your fudgy chocolate mint brownies, keep them at room temperature in an airtight container for up to 3 days. If you prefer, you can refrigerate them for up to a week. For long-term storage, wrap them tightly and freeze for up to 3 months. When ready to enjoy, let them thaw at room temperature and, if desired, warm them in the microwave for about 10 seconds for that soft, gooey texture.

Chef’s Helpful Tips

• Make sure to allow the brownies to cool completely before spreading on the mint layer; this helps the layers stay distinct.
• Use room temperature eggs for better mixing—cold eggs can create lumps in the batter.
• If your brownies deflate a bit after baking, it could be a sign of overmixing. Just mix until ingredients are incorporated.
• Experiment with the mint flavor; if you prefer a more subtle taste, start with less peppermint extract and adjust accordingly.
• For a festive twist, consider sprinkling crushed candy canes on top of the ganache before it sets!

Fudgy chocolate mint brownies are truly a delightful dessert that captures the hearts of chocolate lovers everywhere. With their rich flavor and iconic minty burst, they’re perfect for any gathering or simply as a treat to enjoy with family. So don your apron, gather your ingredients, and don’t hesitate to make a batch (or two!).

Recipe FAQs

Can I use different types of chocolate?

Absolutely! While semi-sweet chocolate gives a perfect balance, you can use dark or even milk chocolate depending on your preference. Just note that different chocolates may affect the sweetness of the ganache.

How can I adjust the mint flavor?

If you love mint, feel free to add a bit more peppermint extract to the filling. Start with a quarter teaspoon and taste as you go, adjusting to your personal preference.

Can I make these brownies a day ahead?

Yes, you can definitely make these brownies in advance! Just store them in an airtight container in the refrigerator. The flavors actually deepen overnight, making them even more delicious.

What if my brownies are too cakey?

If your brownies come out too cakey, it may be due to overmixing or baking them for too long. Keep an eye on the baking time, and use the toothpick test to ensure they come out with moist crumbs instead of dry.
