Ingredients
For the Brownies
- 1 cup unsalted butter
- 2 cups granulated sugar
- 4 large eggs
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour
- 1 cup unsweetened cocoa powder
- 1/2 teaspoon salt
- 1/2 teaspoon baking powder
For the Mint Frosting
- 1 cup powdered sugar

- 1 teaspoon peppermint extract
- Green food coloring (optional)
For the Ganache
- 4 ounces semisweet chocolate, chopped
- 1/2 cup heavy cream
Garnish (Optional)

How to Make St. Patrick’s Day Ultimate Mint Brownies
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Grease your baking pan with butter or cooking spray. Line it with parchment paper to make removing the brownies easier later.
Step 2: Make the Brownie Batter
In a large saucepan, melt the butter over low heat. Once melted, remove it from heat. Stir in the granulated sugar until well mixed. Add each egg one at a time, mixing well after each addition. Finally, stir in the vanilla extract.
Step 3: Combine Dry Ingredients
In another bowl, sift together the all-purpose flour, cocoa powder, salt, and baking powder. Gradually add this mixture to your wet ingredients until fully combined.
Step 4: Bake the Brownies
Pour the brownie batter into your prepared baking pan. Spread it evenly across the pan and bake for 25-30 minutes. Check for doneness by inserting a toothpick; it should come out with moist crumbs attached. Allow cooling completely in the pan.
Step 5: Prepare the Mint Frosting
In a medium bowl, mix together powdered sugar, milk, peppermint extract, and green food coloring if desired. Beat until smooth and fluffy before spreading it evenly over the cooled brownies.
Step 6: Make the Chocolate Ganache
In a small saucepan over medium heat, warm the heavy cream until it begins to simmer. Remove from heat and add chopped semisweet chocolate. Let sit for 1-2 minutes before stirring until fully melted and smooth.
Step 7: Assemble the Brownies
Pour your chocolate ganache over the mint frosting layer. Use a spatula to spread it evenly across. Let set at room temperature or refrigerate until firm.
Step 8: Serve and Enjoy
Once set, cut your brownies into squares. Garnish with chocolate shavings if desired. Enjoy these delightful St. Patrick’s Day treats!
