Ingredients You’ll Need
- ½ cup (113g) unsalted butter: Used to create a rich brownie base. Consider using European-style butter for creamier results.
- 8 ounces (227g) semi-sweet chocolate: Coarsely chopped for melting into the brownie batter. You can substitute with dark chocolate for a more intense flavor.
- ¾ cup (150g) firmly packed brown sugar: Adds moisture and a deep flavor to the brownies. Light or dark brown sugar works in this recipe.
- ¼ cup (50g) granulated sugar: Balances the richness of the brown sugar. You can replace it with coconut sugar for a healthier option.
- 3 large eggs: Room temperature eggs help the batter emulsify and blend smoothly; use egg substitutes if needed.
- 1 teaspoon vanilla extract: Enhances the overall flavor of the brownies. Always choose pure vanilla extract for the best taste.
- ¾ cup (90g) all-purpose flour: Gives structure to the brownies. For gluten-free options, use a 1:1 gluten-free flour blend.
- ¼ teaspoon salt: Enhances flavors and balances sweetness.
- ½ cup (113g) unsalted butter (softened): This one is for the mint frosting layer, making it creamy. Let it sit at room temperature for about an hour to soften.
- 2 cups (240g) powdered sugar: Sweetens the frosting. If you’re concerned about the sweetness, you can adjust the amount to your taste.
- ¼ cup (60ml) milk or cream: Adds moisture to the frosting. Substitute with almond milk or coconut cream for dairy-free options.
- ½ to ¾ teaspoon peppermint extract: Imparts a refreshing minty flavor. Be careful not to overdo it—start with half and taste before adding more!
- 2 drops green liquid or gel food coloring: Just to give the frosting that festive St. Patrick’s Day touch; this is optional.
- 1 cup (175g) semi-sweet chocolate chips: For the ganache. You can use white chocolate chips for contrast if desired.
- ⅔ cup (160ml) heavy cream: Combined with chocolate chips for a rich ganache layer. Whipping cream can be used in a pinch.
How to Make Mint Chocolate Brownies | Easy St Patrick’s Day Fudgy Brownies
Preheat the Oven: Start by preheating the oven to 350ºF (177ºC). Line an 8″ or 9″ square baking pan with foil for easy removal and give it a quick spray with nonstick spray.
Melt the Chocolate and Butter: In a medium saucepan over medium heat, combine ½ cup (113g) unsalted butter and 8 ounces (227g) coarsely chopped semi-sweet chocolate. Stir frequently until the mixture is completely smooth. Afterward, allow it to cool for about 15 minutes before moving on.
Combine Sugars and Eggs: Whisk ¾ cup (150g) firmly packed brown sugar and ¼ cup (50g) granulated sugar into the cooled chocolate mixture until well combined. Crack in 3 large eggs one at a time, whisking after each addition for a smooth texture. Finish up by whisking in 1 teaspoon vanilla extract.
Add Dry Ingredients: Carefully fold in ¾ cup (90g) all-purpose flour and ¼ teaspoon salt. Stir gently until everything is just combined; overmixing can lead to tough brownies.
Bake the Brownies: Pour the brownie batter into your prepared pan. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out mostly clean with a few moist crumbs. Let the brownies cool completely in the pan before proceeding to the next layers.
Make the Mint Frosting: In a large bowl (using a handheld mixer or stand mixer with a paddle attachment), beat ½ cup (113g) softened unsalted butter on medium speed until it’s creamy—about 2 minutes. While the mixer is on low, gradually add in 2 cups (240g) powdered sugar, ½ to ¾ teaspoon peppermint extract, and ¼ cup (60ml) milk or cream. Once combined, splash a couple of drops of green food coloring in, then increase to medium speed and beat until smooth—about 3 minutes. Adjust consistency with more milk or powdered sugar if necessary.
Prepare the Ganache: Pour 1 cup (175g) semi-sweet chocolate chips into a small bowl and set it aside. In a small saucepan over medium heat, warm ⅔ cup (160ml) heavy cream—whisk occasionally until steaming but not boiling. Remove from heat and pour the cream over the chocolate chips. Whisk until the mixture is perfectly smooth, then let it cool for at least 20 minutes.
Assemble the Brownies: Once the brownie layer is completely cool, spread the mint frosting evenly over it with a spatula. Quickly pour the chocolate ganache over the mint layer, gently guiding it into the corners as needed.
Chill to Set: Place the baking pan in the refrigerator to allow the ganache to set fully—this will take at least 2 hours.
Cut and Serve: When ready to enjoy, lift the brownies out by pulling on the foil overhang. Peel back the foil and place the brownie slab onto a large cutting board. Use a sharp knife for quick cuts, cleaning it between each slice to avoid smearing the ganache.
Storing & Reheating
Store these fudgy brownies at room temperature in an airtight container for up to 3 days. For longer storage, refrigerate them for up to a week, ensuring they’re in a sealed container to keep them moist. You can also freeze them for up to 3 months—simply wrap individual squares tightly in plastic wrap and place them in a freezer-safe bag. When it’s time to enjoy them, thaw them in the refrigerator overnight. The flavor and texture remain delightful, but if you prefer them warm, pop them in the microwave for about 10 seconds.
Chef’s Helpful Tips
- Don’t overmix: When adding the flour to the brownie batter, stir until just combined to keep them tender.
- Use room temperature ingredients: Room temperature eggs and butter emulsify better, resulting in a smooth batter.
- Test for doneness: Stick a toothpick into the center of the brownies; it’s okay if a few moist crumbs cling to it, but it shouldn’t be wet batter.
- Customize the mint: Adjust the peppermint extract to cater to your taste; start with less and add more if you desire a stronger mint flavor.
- Make-ahead: Brownies can be made in advance—crafted the day before and allowed to sit overnight for the flavors to meld beautifully.
These Mint Chocolate Brownies are truly a special treat. They perfectly balance rich chocolate, creamy mint, and smooth ganache, resulting in a dessert that’s a hit for any gathering, especially around St. Patrick’s Day! Make them for yourself, and perhaps share a few—though you might find it hard to resist keeping them all to yourself.
Recipe FAQs
Can I make these Mint Chocolate Brownies gluten-free?
Yes! Simply substitute the all-purpose flour with a gluten-free flour blend. Look for one that contains xanthum gum for better structure.
How can I make these brownies even more fudgy?
For an extra fudgy texture, try adding an additional egg to the batter. This creates a denser brownie that most chocolate lovers will adore.
Can I use different kinds of chocolate?
Absolutely! You can experiment with dark chocolate or even white chocolate chips for a different flavor profile. Just keep in mind that the overall taste and sweetness may change.
How do I know when my brownies are done baking?
Brownies are done when the edges look set and the center appears slightly underbaked—when a toothpick comes out with a few moist crumbs, it’s perfect!
