Step 1: Preheat the Oven. Start by preheating your oven to 350°F (175°C). This ensures that your brownies bake evenly and come out perfectly fudgy.
Step 2: Mix the Wet Ingredients. In a large mixing bowl, combine the oil and granulated sugar. Whisk in the eggs one at a time, incorporating them fully before adding the next. Stir in the vanilla extract until well combined.
Step 3: Combine the Dry Ingredients. In a separate bowl, whisk together the cocoa powder, salt, and flour. Gradually add this mixture to the wet ingredients, stirring until just combined. Be careful not to overmix; a few lumps are perfectly fine.
Step 4: Bake the Brownies. Pour the brownie batter into your prepared 9x13 inch baking pan, spreading it evenly. Bake for 25-30 minutes or until a toothpick inserted in the center comes out with a few moist crumbs. Allow the brownies to cool completely in the pan.
Step 5: Prepare the Mint Frosting. In a medium bowl, beat together the room temperature butter, powdered sugar, peppermint extract, and milk. If desired, add a few drops of green food coloring to achieve a vibrant mint color. Mix until smooth and creamy.
Step 6: Frost the Brownies. Once the brownies are completely cooled, spread the mint frosting evenly over the top using a spatula. This layer adds a refreshing touch that truly elevates the brownies.
Step 7: Make the Chocolate Ganache. In a double boiler or microwave-safe bowl, melt the butter. Stir in the unsweetened cocoa powder until fully combined. Gradually mix in the powdered sugar, followed by the milk and vanilla extract. Continue to mix until the ganache is smooth and glossy.
Step 8: Drizzle the Ganache. Pour the chocolate ganache over the frosted brownies, allowing it to drip down the sides for a beautiful finish. Let the ganache set for a few minutes before slicing into squares.
Step 9: Slice & Serve. Using a sharp knife, cut the brownies into squares. Serve them on a platter and watch as your guests delight in these Next-Level Mint Brownies That Outshine the Rest.
