There’s something undeniably magical about the combination of rich chocolate and cool mint. I’ve always had a soft spot for desserts that strike a perfect balance between bold and refreshing flavors, and these Chocolate Mint Brownies check every box.

They’re perfect for holidays, potlucks, or anytime you want a show-stopping dessert.

What Kind of Mint Flavoring Should I Use?

Peppermint extract is the classic go-to, giving you that familiar clean, sharp flavor. But if you prefer a milder note, crème de menthe extract is a delicious alternative. Just avoid using mint essence or oil unless you’re comfortable adjusting the quantity—those can be incredibly strong and overpowering.

Options for Substitutions

Butter: You can use plant-based butter for a dairy-free version.
Flour: Swap in a gluten-free flour blend to make these gluten-free.
Chocolate Chips: Dark, milk, or semi-sweet chips all work well depending on your taste.
Food Coloring: Want a natural version? Use matcha or spinach powder instead of green food dye.
Sugar: Coconut sugar or monk fruit sweetener can replace granulated sugar if you’re reducing refined sugars.

Ingredients for Chocolate Mint Brownies

Unsalted Butter – Adds richness and helps create that dense, fudgy texture in the brownie base.
Granulated Sugar – Sweetens the brownies and helps achieve the perfect crackly top.
Eggs – Provide structure and moisture; essential for binding the ingredients together.
Vanilla Extract – Enhances the chocolate and mint flavors with warm, aromatic undertones.
All-Purpose Flour – The base of the brownie, creating structure without making them cakey.
Unsweetened Cocoa Powder – Adds deep, intense chocolate flavor to the brownie layer.
Salt – Balances the sweetness and enhances overall flavor.
Semi-Sweet Chocolate Chips – Melted into the batter for extra chocolate richness.
Powdered Sugar – Used in the mint filling to create a smooth, sweet texture.
Peppermint Extract – Gives the signature cool mint flavor to the middle layer.
Green Food Coloring – Optional, but creates that classic minty visual contrast.
Heavy Cream or Milk – Softens the mint layer to make it smooth and spreadable.
Chocolate Ganache or Melted Chocolate (for topping) – Adds a shiny, rich finish to the top layer.

Step 1: Prepare the Brownie Base

Preheat your oven to 350°F (175°C) and line a 9×13-inch pan with parchment paper. Melt the butter and chocolate chips together until smooth, then stir in the sugar, eggs, and vanilla. Once combined, fold in the cocoa powder, flour, and salt. Pour the mixture into the pan and bake for 25–30 minutes or until a toothpick comes out with a few moist crumbs.

Step 2: Make the Mint Filling

While the brownie layer cools, beat together the softened butter, powdered sugar, peppermint extract, and a splash of cream or milk. Add green food coloring a drop at a time until the desired minty hue is reached. Spread this evenly over the cooled brownies and place in the fridge to set.

Step 3: Add the Chocolate Topping

Melt the chocolate chips (or prepare a ganache) and gently spread it over the chilled mint layer. Use a spatula to smooth it out evenly. Refrigerate the entire pan again until the chocolate topping is firm and set.

Step 4: Slice and Serve

Once fully chilled, lift the brownies out using the parchment paper. Use a sharp knife (cleaning between cuts) to slice into even squares. Serve cold or at room temperature.

How Long to Prepare Chocolate Mint Brownies

Prep Time: The total preparation takes about 25 minutes. This includes melting the butter and chocolate, mixing the batter, and making the mint layer. You’ll also need a few minutes to spread and chill each layer.

Bake & Chill Time: Baking the brownies takes 25–30 minutes. After baking, allow at least 30 minutes for cooling, 15 minutes to chill the mint layer, and another 20–30 minutes to firm up the chocolate topping. In total, give yourself 1 hour and 45 minutes from start to finish (including chill time).

Tips for Perfect Chocolate Mint Brownies

Always let the brownie layer cool completely before adding the mint layer to prevent it from melting.
Use high-quality cocoa powder and chocolate chips for the richest flavor.
Add food coloring gradually—a little goes a long way for that vibrant mint green.
For cleaner cuts, chill the entire pan thoroughly and use a hot, clean knife.
Store brownies in the fridge for the best texture and to keep the mint layer stable.

Watch Out for These Mistakes While Cooking

Overbaking: This can lead to dry, cakey brownies instead of moist and fudgy.
Adding mint layer too soon: The heat from the brownie base can cause it to melt or separate.
Skipping the chill time: If layers aren’t properly set, they’ll smear when cut.
Using too much extract: Mint extract is potent—a few drops too many can overpower the dessert.
Uneven spreading: Take your time to smooth each layer evenly for the best presentation.

What to Serve With Chocolate Mint Brownies?

1. A scoop of vanilla ice cream

The contrast of warm brownie and cold, creamy vanilla is heavenly.

2. Hot coffee or espresso

The bitterness of coffee perfectly complements the sweetness of the brownie.

3. Fresh raspberries or strawberries

Add a fresh, fruity burst that balances the richness.

4. Whipped cream

A light and fluffy addition that won’t overpower the brownie.

5. Peppermint tea

Echoes the mint in the brownie and makes for a cozy pairing.

Storage Instructions

Room Temperature: You can store these at room temperature in an airtight container for up to 2 days. However, the mint and chocolate layers may soften.
