These dense, chocolatey squares blend deep cocoa flavors with a cool mint layer, topped by a smooth chocolate ganache. The base is rich and fudgy, studded with semi-sweet chips for added texture. A creamy mint layer adds brightness, complemented by the glossy ganache finish. Perfectly balanced sweet and refreshing, these treats bake in under an hour and can be stored chilled for days. Ideal for those craving a sophisticated dessert combining chocolate and mint nuances.
My roommate Sarah burst into the kitchen last winter with a serious craving for mint chocolate anything, and somehow that turned into us huddled over a mixing bowl at midnight trying to perfect these green mint brownies. We may have eaten the first batch straight from the pan with forks, standing in our pajamas while snow fell outside the window.
Last summer I made these for a garden party and watched them disappear in under ten minutes, with three different people asking for the recipe before they even finished chewing. My neighbor Tom still texts me every few months asking when I will bake another batch.
Ingredients
- Unsalted butter: Room temperature butter creams into silkier frostings and melts more evenly into brownie batter
- Granulated sugar: Creates that crackly, shiny top we all love on good brownies
- Large eggs: Bring structure and richness, so do not skip or substitute
- Vanilla extract: Pure vanilla makes chocolate taste more chocolatey somehow
- All purpose flour: Just enough to hold everything together without turning cakey
- Unsweetened cocoa powder: Dutch process cocoa gives the deepest chocolate flavor
- Salt: Enhances chocolate and balances sweetness
- Semisweet chocolate chips: Melts into pockets of goo while keeping texture
- Powdered sugar: Sifting first prevents lumps in your mint frosting
- Whole milk: Thins frosting to spreadable consistency without making it runny
- Peppermint extract: A little goes a very long way, so start with less
- Green food coloring: Makes these instantly recognizable and festive
Instructions
- Get everything ready:
- Preheat your oven to 175°C (350°F) and line a 20x20 cm (8x8-inch) baking pan with parchment paper, letting some hang over the sides like little handles.
- Melt and mix:
- Melt 115 g butter in a medium saucepan over low heat, then whisk in granulated sugar until it looks like wet sand.
- Add the wet ingredients:
- Beat in eggs one at a time, then stir in vanilla extract until everything is glossy and smooth.
- Dry ingredients come next:
- Sift in flour, cocoa powder, and salt, then fold gently until you cannot see white streaks anymore.
- Add the chocolate:
- Stir in 100 g semisweet chocolate chips, saving some for sprinkling on top if you want extra chocolate.
- Bake the base:
- Pour batter into your prepared pan, smooth the top, and bake for 22 to 25 minutes until a toothpick comes out with moist crumbs.
- Make the mint frosting:
- Beat 60 g softened butter until creamy, then gradually mix in powdered sugar, peppermint extract, and 1 tbsp milk.
- Color and spread:
- Add green food coloring drop by drop until you get the shade you want, then spread evenly over cooled brownies and chill for 15 minutes.
- Prepare ganache:
- Microwave 100 g chocolate chips and 30 g butter in 20 second bursts, stirring between each until completely smooth.
- Finish and set:
- Pour ganache over the mint layer, spread it gently, and chill for 30 minutes until the chocolate is firm.
- Cut and serve:
- Lift the whole thing out using parchment paper, cut into 16 squares, and try not to eat three immediately.
My niece helped me decorate these last Christmas and got green food coloring everywhere, including somehow on the ceiling, but those brownies were the most talked about dessert of the whole holiday season.
Making The Layers Work
Temperature matters more than most recipes admit. Warm brownies melt frosting into a sad puddle, but freezing cold brownies make ganache seize up into streaks.
Getting The Green Right
Natural food coloring gives a softer, more minty looking green than the bright artificial stuff. Add color drop by drop because you can always add more.
Storage And Serving
These actually taste better after chilling overnight because the flavors meld together. Room temperature brownies are fudgier, but cold ones hold their shape better for serving.
- Use a hot knife for cleaner cuts and wipe between slices
- Let them sit at room temperature for 10 minutes before serving for the best texture
- Stack between parchment paper if you need to layer them in a container
Every time I bake these now, I think about that snowy night with Sarah and how the best recipes always start with someone saying I wonder if we could.
