Why You’ll Love These Mint Chocolate Brownies

The Fudgy Texture You Crave

The base of this recipe starts with a boxed brownie mix, but don’t let that fool you. The result is ultra-moist, dense, and fudgy with that irresistible crackly top. You can use your favorite brand — the trick is baking it just right (we’ll get to that).

Cool, Creamy Mint Frosting Layer

Once your brownies cool, on goes a dreamy layer of peppermint frosting. Made with cream cheese, powdered sugar, and a splash of peppermint extract, it’s smooth, fresh, and just the right amount of sweet. Add a few drops of green food coloring for that classic minty look, if you want to give it a fun and festive touch.

Chocolate Mint Ganache Topping (Optional but WOW)

Top it all with a melted mix of chopped semi-sweet chocolate and Andes mints. When it sets, it creates a glossy, snappy layer that contrasts perfectly with the soft frosting underneath.

Easy Boxed Mix Hack That Tastes Homemade

Using a boxed mix means less measuring and less mess. But the added layers make it taste like you spent hours in the kitchen (your secret’s safe with us).

Ingredients You’ll Need

Making mint chocolate brownies from scratch (with a boxed twist) is easier than you think. Here’s everything you’ll need, organized by layer for smooth baking:

For the Brownie Base

• Cooking spray (for greasing the pan)
• 1 box fudgy brownie mix
• Eggs, oil, and water (according to brownie mix package directions)

For the Mint Frosting

• 1 stick (113g) unsalted butter, room temperature
• 3 oz (85g) cream cheese, room temperature
• 2¼ tsp peppermint extract
• 1 pinch kosher salt
• 1¾ cups (198g) powdered sugar
• 1 tbsp heavy cream
• Green liquid food coloring (optional, for classic minty color)

For the Chocolate Topping (Optional, but amazing)

• 3 oz (85g) semi-sweet chocolate, chopped
• 12 chocolate mints (like Andes), finely chopped (about ⅓ cup, optional)

💡 Pro Tip: You can skip the topping and just add chopped Andes mints right over the frosting if you're short on time.

How to Make Mint Chocolate Brownies (Step-by-Step)

1. Bake the Brownie Base

1. Preheat your oven according to the brownie mix directions (usually around 350°F/175°C).
2. Lightly grease a 9×9-inch baking pan with cooking spray to prevent sticking and ensure easy removal
3. Prepare the brownie batter according to the instructions on the box, making sure to mix until smooth and well combined.
4. Pour into the pan and bake as directed.
5. Remove from oven and let it cool completely before frosting.

✅ Don’t rush this part! A hot brownie base will melt your frosting.

2. Make the Creamy Mint Layer

1. In a large bowl, beat the butter and cream cheese until smooth and fluffy.
2. Add peppermint extract, salt, and powdered sugar. Beat until light and creamy.
3. Stir in the heavy cream along with a few drops of green food coloring, if desired, for that classic minty hue. Mix until combined.
4. Spread evenly over the cooled brownies using an offset spatula.
5. Chill in the fridge for 15–20 minutes to firm it up before adding the chocolate topping.

3. Melt the Chocolate for the Topping

1. Place chopped chocolate and Andes mints in a microwave-safe bowl.
2. Microwave in 30-second intervals, stirring between each burst, until the mixture is fully melted and smooth.
3. Let it cool slightly (about 3 minutes) so it doesn’t melt the frosting layer.

4. Layer It Up and Chill

1. Gently pour the melted chocolate mixture over the mint layer, spreading it evenly with a spatula.
2. Gently spread with a spatula to cover completely.
3. Place the pan in the refrigerator and chill for about 30 minutes, or until the chocolate topping is firm and set.

5. Slice and Serve

1. For clean, neat slices, run a sharp knife under hot water, wipe it dry, and then cut into squares. Repeat between cuts for best results.
2. Cut into squares and enjoy every fudgy, minty bite!

💡 Optional: Sprinkle extra chopped Andes mints on top before the chocolate sets for a little extra flair!

Tips for the Best Mint Brownies Ever

Want bakery-quality mint chocolate brownies at home? These simple tips will make a BIG difference:

Use Room Temperature Ingredients

Soft butter and cream cheese blend smoothly into that mint layer — no lumps, no stress.

Don’t Overbake the Brownies

Pull them out when a toothpick comes out with just a few moist crumbs. Overbaking = dry brownies = sadness.

Let Layers Set Between Steps

Cool the brownies completely before frosting. And chill the mint layer before pouring on the chocolate. It’s the key to those clean, Insta-worthy layers.

Add Extra Mint Candies on Top

Chopped Andes, peppermint bark, or even crushed candy canes during the holidays. Adds crunch and looks fancy with zero effort.

Variations and Swaps

Want to shake things up? These brownie tweaks are super fun:

• Gluten-Free Version: Just use your favorite gluten-free brownie mix.
• Swap the Extract: Prefer spearmint or vanilla? Go for it — just use the same amount.
• White Chocolate Topping: Use white chocolate chips instead of semi-sweet for a sweeter twist.
• Loaded Brownies: Add mini chocolate chips or crushed Oreos into the brownie batter before baking.

🎯 Bonus Idea: Add a thin layer of melted marshmallow fluff between the brownie and mint layer for an epic twist!

Storage and Freezing Tips

How to Store Mint Chocolate Brownies

• Store the bars in an airtight container in the refrigerator for up to 5 days to keep them fresh and delicious.
• The mint frosting and chocolate topping stay fresher chilled.

Can I Freeze Them? Absolutely!

• To freeze, tightly wrap the uncut brownies—whether still in the pan or as a whole slab—in plastic wrap, then add a layer of foil for extra protection. They’ll remain fresh in the freezer for up to 2 months—just thaw them in the fridge before serving.
• Or freeze individual squares wrapped in parchment + ziplock bag.

How to Thaw

• Thaw overnight in the fridge for best texture.
• For quicker thawing, leave a square at room temp for 30–60 minutes.

FAQ – Mint Chocolate Brownies

Do mint brownies need to be refrigerated?

Yes! Because of the cream cheese in the mint frosting, it’s best to store these brownies in the fridge. They’ll stay fresh for up to 5 days when stored in an airtight container. You can enjoy them cold or let them sit at room temp for 10–15 minutes for a softer bite.

Are mint brownies good?

Oh yes — mint chocolate brownies are a total fan favorite! They combine the rich, fudgy goodness of chocolate with a cool, creamy peppermint layer. It’s a refreshing twist on a classic dessert that works year-round, especially during the holidays or for mint lovers.

Can you freeze chocolate mint brownies?

Absolutely! Mint brownies freeze really well. Just wrap them tightly (either whole or sliced), and store in a freezer-safe bag or container for up to 2 months. When you’re ready to enjoy, thaw them in the fridge overnight or on the counter for about 30–60 minutes.

Why does mint chocolate work?

The combo is popular because it’s perfectly balanced. Chocolate brings richness and sweetness, while mint adds a fresh, cool contrast. The flavors don’t overpower each other — they complement in a way that feels indulgent and refreshing at the same time.

Can I use fresh mint instead of extract?

Technically yes, but it’s tricky. Fresh mint has a milder, grassy flavor that doesn’t always come through in baked goods. If you want to try it, infuse the butter with chopped mint leaves and strain it before using. Otherwise, peppermint extract is the easier (and more reliable) way to get that bold flavor.

What kind of chocolate is best for mint brownies?

Semi-sweet chocolate is the perfect choice—it’s rich enough to balance the cool mint flavor without overpowering it with sweetness. You can also mix in chopped Andes mints or use dark chocolate for a more intense flavor. Milk chocolate is softer and sweeter, but still tasty if you’re after a milder bite.
