Decadent Chocolate Mint Cookies

The December wind swept through my little kitchen as four neighborhood kids barged in with red cheeks and mittened hands. They’d just finished shoveling snow for a neighbor, and their reward? “Something minty, please!” one of them declared while kicking off his boots.

Earlier that day, I had been organizing my spice rack when I found a nearly full bottle of mint extract tucked behind the cinnamon. That serendipitous moment led me to these Chocolate Mint Cookies, a recipe I hadn’t made since our local library’s cookie swap three winters ago.

While the kids defrosted with mugs of hot cocoa, I got to work. The smell of cocoa and vanilla buttercream mingling with minty essence quickly filled the house. As I spread the pastel green frosting across the soft chocolate cookies, they peeked over the counter, eyes wide, already choosing which ones they’d claim. One even asked if he could “taste test” for poison twice. Moments later, the kitchen was silent except for the joyful crunch of ganache cracking under the frosting.

These cookies became the highlight of that snowy afternoon and not just for the kids. My elderly neighbor, who had only planned to stop by for mail, left with a wrapped bundle and a smile that lingered longer than the warmth of the cookies. It’s amazing what a tray of Chocolate Mint Cookies can do for a community on a cold winter’s day.

Key Ingredients

For the Chocolate Cookies

• ½ cup unsalted butter, room temperature
• 1 cup granulated sugar (200 g)
• 1 teaspoon vanilla
• 1 large egg, room temperature
• 1¼ cups flour (163 g), fluffed and leveled
• ⅓ cup unsweetened cocoa powder (30 g)
• ½ teaspoon baking soda
• ¼ teaspoon salt

For the Mint Frosting

• 1½ cups powdered sugar
• ½ cup unsalted butter, room temperature
• 1 tablespoon milk
• ½–1 teaspoon mint extract, to taste
• Green food coloring (optional)

For the Ganache

• ¾ cup semisweet chocolate chips or chopped chocolate (130 g)
• 1 tablespoon oil

Tools Needed

• Electric mixer
• Mixing bowls (at least 3)
• Measuring cups and spoons
• Rubber spatula
• Baking sheets
• Parchment paper
• Cooling rack

Cooking Instructions

Step 1: Make the Cookie Dough

Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper. In a large bowl, cream the butter and sugar together with an electric mixer for 3–4 minutes until light and smooth. Beat in the vanilla and egg until well combined.

Step 2: Add the Dry Ingredients

Whisk together flour, cocoa powder, baking soda, and salt in a separate bowl. Gradually add the dry mixture to the wet ingredients and mix until a dough forms. It should hold its shape and be slightly tacky but not overly sticky.

Step 3: Bake the Cookies

Roll the dough into about 16 balls, around 1¾ inches each. Space them evenly on the baking sheets and bake for 8–10 minutes. The centers should look slightly glossy while the edges are set. Let them cool on the tray for 10 minutes, then transfer to a rack to cool completely.

Step 4: Prepare the Mint Frosting

In a clean bowl, beat together powdered sugar, butter, milk, mint extract, and food coloring (if using) until creamy and spreadable. Adjust with extra sugar or milk for consistency. Spread frosting generously over each cooled cookie and freeze for at least 15 minutes.

Step 5: Add the Ganache

In another bowl, mix chocolate and oil. Microwave in 30-second intervals, stirring until just melted and smooth. Spoon ganache over the chilled cookies the cold surface will keep the chocolate from running off. Let set before serving.

Mistakes to Avoid & Solutions

Using soft butter instead of room temperature
Softened too much butter will make your cookies spread excessively.
Solution: Let butter sit at room temperature for 30 minutes until cool but slightly pliable.

Too sticky dough
If your dough is too sticky to roll, shaping becomes difficult and messy.
Solution: Chill the dough for 15–20 minutes, or add 1 tablespoon of flour at a time until manageable.

Frosting too thin or thick
A runny frosting will slide off the cookie, while overly stiff frosting is hard to spread.
Solution: Add more powdered sugar to thicken, or a splash of milk to loosen the texture.

Ganache sliding off the cookies
Warm cookies or frosting can cause the ganache to drip uncontrollably.
Solution: Freeze the frosted cookies for at least 15 minutes before spooning on the ganache.

Overbaking the cookies
Excess baking time leads to dry, crumbly cookies with a tough bite.
Solution: Bake just until edges are set and centers appear slightly glossy.

Adding too much mint extract
An overpowering mint flavor can dominate the cookie and mask the chocolate.
Solution: Start with ½ teaspoon, then taste and adjust gradually if needed.
