How to Make Mint Chocolate Brownies (Step-by-Step)
🟤 Step 1: Prepare the Brownie Batter
- Melt butter and chopped chocolate together in a saucepan over medium heat or microwave in 20-second bursts until smooth. Let cool for 10 minutes.
- Stir in granulated and brown sugars until well combined.
- Add eggs one at a time, whisking thoroughly between each addition. Stir in vanilla.
- Fold in flour, cocoa powder, and salt gently to keep the batter fudgy.
- Pour into a parchment-lined 9×13-inch pan. Bake at 177°C (350°F) for 35–36 minutes. The edges should pull away slightly, and a toothpick should come out with moist crumbs.
- Cool completely before frosting.
🟩 Step 2: Make the Mint Layer
- Beat softened butter until creamy.
- Add confectioners’ sugar and milk, starting on low speed. Beat until fluffy.
- Mix in peppermint extract and optional food coloring.
- Spread evenly over cooled brownies. Chill in the fridge for at least 1 hour to set.
🍫 Step 3: Add the Chocolate Topping
- Melt butter and chocolate chips until smooth.
- Pour over the chilled mint frosting. Spread quickly with an offset spatula before it sets.
- Refrigerate for another hour minimum to firm up the layers.
- Cut into clean squares using a hot, sharp knife. Wipe between cuts for neat edges.
Tips for Perfect Layers & Clean Cuts
- Always chill between layers to prevent them from blending together.
- Use parchment paper with overhang for easy removal from the pan.
- Let brownies sit at room temperature for 20 minutes before serving for the best texture and flavor.
- A hot knife (run under hot water and wiped dry) helps get sharp, bakery-style slices.
