The magic of this Brownie Cookies with Mint Frosting Recipe comes from a handful of simple but thoughtfully chosen ingredients.

- 4 eggs: Binds the ingredients and adds moisture for tender cookie centers.
- 1 1/3 cups granulated sugar: Sweetens the cookies just right, balancing bitter chocolate notes.
- 1 teaspoon vanilla extract: Enhances depth of flavor with a warm, aromatic touch.
- 1/2 cup all-purpose flour: Gives structure while keeping the cookies soft and chewy.
- 1/2 teaspoon baking powder: Helps the cookies rise slightly without losing their brownie-dense feel.
- 1 cup semi-sweet chocolate chips: Adds melty pockets of chocolate throughout for extra indulgence.
- 3 cups powdered sugar: The base for the fluffy, sweet frosting topping.
- 6 Tablespoons butter (softened to room temperature): Creates a creamy texture in the frosting.
- 6 Tablespoons heavy cream or milk: Adjusts frosting to the perfect consistency.
- 1 teaspoon peppermint extract: Infuses the frosting with that unmistakable refreshing mint flavor.
- 3 to 4 drops green food coloring: Gives the frosting a festive and inviting minty green hue.
How to Make Brownie Cookies with Mint Frosting Recipe
Step 1: Prepare Your Baking Sheets and Oven
Start by preheating your oven to 350 degrees Fahrenheit. Line two baking sheets with parchment paper or liberally spray them with non-stick spray to ensure your cookies slide off effortlessly after baking. This prep step sets the stage for perfectly formed brownie cookies later on.
Step 2: Melt Chocolate and Butter
In a large microwave-safe bowl, combine the chopped semi-sweet chocolate and butter. Microwave in 30-second bursts, stirring in between, until melted and silky smooth. This warm chocolate-butter mixture will be the luscious core of your brownie dough. Once melted, let it cool for about 10 minutes so it doesn’t scramble your eggs in the next step.
Step 3: Whisk Eggs, Sugar, and Vanilla Then Combine
In a separate bowl, whisk together the eggs, granulated sugar, and vanilla extract until smooth and slightly frothy. Slowly pour in the cooled chocolate mixture and stir just until combined. Next, fold in the flour and baking powder for perfect texture, followed by the chocolate chips for delightful pockets of melty goodness. Cover the bowl with plastic wrap and chill the dough in the fridge for 30 minutes—this step helps your cookies hold their shape and enhances flavor melding.
Step 4: Scoop and Bake the Cookies
Once your dough is well chilled, drop generous 2-tablespoon scoops onto the prepared baking sheets, spacing them evenly. Bake at 350 degrees Fahrenheit for 10 to 12 minutes—be careful not to overbake as you want your cookies to remain fudgy inside. When done, let them cool completely on the baking sheets so they firm up before frosting.
Step 5: Make the Mint Frosting and Frost Your Cookies
In a mixing bowl, beat together powdered sugar and softened butter until fully combined and creamy. Gradually add the heavy cream or milk until the frosting reaches your desired consistency—soft but spreadable is perfect. Stir in peppermint extract and then add 3 to 4 drops of green food coloring until you achieve a minty green shade. Once your cookies are cooled, slather them generously with this bright, refreshing frosting. For an added touch, feel free to sprinkle extra chocolate chips on top to amp up the decadence.
How to Serve Brownie Cookies with Mint Frosting Recipe
Garnishes
Sprinkle a handful of mini chocolate chips or crushed peppermint candy on top of the mint frosting to elevate both presentation and texture. A light dusting of cocoa powder can also add a sophisticated finish. These small touches make your brownie cookies look as fabulous as they taste.
Side Dishes
These brownie cookies shine bright on their own but pair wonderfully with a tall glass of cold milk or a warm cup of coffee to balance sweetness. For a festive twist, serve alongside fresh raspberries or a scoop of vanilla ice cream to complement the rich chocolate and cool mint flavors.
Creative Ways to Present
Arrange your Brownie Cookies with Mint Frosting Recipe on a decorative platter lined with fresh mint leaves for an eye-catching presentation perfect for parties or holiday gatherings. You could also stack them like a mini tower tied with a ribbon to gift to friends or family. Presentation turns every bite into an event.
Make Ahead and Storage
Storing Leftovers
Keep any leftover brownie cookies in an airtight container at room temperature for up to 3 to 4 days to maintain freshness and texture. The frosting stays creamy and the brownie base stays tender during this time, so you can enjoy them days after baking without compromise.
Freezing
If you want to save these treats longer, freeze the baked and cooled cookies without frosting in a single layer on a baking sheet first, then transfer them to a freezer-safe container or bag. They will keep well for up to 2 months. When you’re ready to enjoy, thaw completely before applying the mint frosting for the best texture.
Reheating
To gently warm your cookies, especially if frozen, place them in a 300-degree Fahrenheit oven for about 5 minutes. This helps revive that just-baked softness and melts the chocolate chips ever so slightly. Avoid microwaving as it may make the frosting too soft or runny.
FAQs
Can I use dark chocolate instead of semi-sweet chocolate for the brownie base?
Absolutely! Dark chocolate will give your brownie cookies a richer, slightly more intense chocolate flavor. Just be mindful that it could make the cookies a bit less sweet, so you might want to adjust the sugar slightly based on your preference.
Is there a substitute for peppermint extract in the frosting?
If peppermint extract isn’t your thing, you can try vanilla or even almond extract for a different but equally delicious twist. However, using peppermint is what gives these brownie cookies their signature refreshing flavor, so it’s worth using it if possible.
How do I prevent the cookies from spreading too much while baking?
Chilling the dough for at least 30 minutes is key—it firms up the butter and chocolate, helping the cookies hold their shape. Also, avoid overbaking since these are meant to stay fudgy and soft.
Can I make these cookies gluten-free?
You can substitute the all-purpose flour with a gluten-free baking blend that measures cup-for-cup. Just be sure the baking powder you use is gluten-free as well to keep the recipe safe for gluten-sensitive eaters.
What’s the best way to get the frosting to a perfect consistency?
Start by beating your powdered sugar and butter thoroughly, then add your cream or milk gradually. You want a frosting that’s thick enough to hold its shape but still smooth enough to spread easily. If it’s too stiff, add a little more cream; if too runny, add more powdered sugar.
Final Thoughts
This Brownie Cookies with Mint Frosting Recipe is truly a crowd-pleaser that combines the fudgy decadence of brownies with the playful format of cookies topped by a refreshing, creamy mint frosting. Whether you’re making them for a holiday party, a cozy night in, or simply to satisfy your chocolate cravings, these treats will not disappoint. Give them a try—you’ll be so happy you did!

- 1 teaspoon peppermint extract

Instructions
- Prepare Brownie Mixture: Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or lightly spray them with non-stick spray to prevent sticking.
- Melt Chocolate and Butter: Place the chopped semi-sweet chocolate and butter in a large microwave-safe bowl. Microwave in 30-second increments, stirring after each interval until the mixture is fully melted and smooth. Set aside to cool for about 10 minutes.
- Combine Eggs and Sugar: In a separate bowl, whisk the eggs, granulated sugar, and vanilla extract together until well combined. Slowly pour the cooled chocolate mixture into the egg mixture, stirring until fully incorporated.
