This chocolate mint cookie recipe has been my secret weapon for holiday gatherings and special occasions for years. The combination of chewy chocolate base, creamy mint frosting, and rich chocolate ganache creates an irresistible triple-layer treat that disappears within minutes whenever I serve them.
I first made these cookies during a snowstorm when my children were begging for something sweet but we couldn't get to the store. They've become such a family tradition that my kids now help make them each Christmas, with the youngest always insisting on being in charge of the green food coloring.
Ingredients
- Unsalted butter: Adds richness to both cookie base and frosting. Quality matters here so choose a good European-style butter if possible
- Granulated sugar: Creates that perfect chewy cookie texture while powdered sugar gives the frosting its smooth consistency
- Vanilla extract: Balances the chocolate flavor in the base. Use pure extract rather than imitation for best results
- Mint extract: Provides the signature flavor. Start with less and add more to taste as brands vary in strength
- Egg: Binds everything together and contributes to the chewy texture. Room temperature is crucial for proper mixing
- All-purpose flour: Provides structure. For a healthier twist whole wheat works surprisingly well
- Unsweetened cocoa powder: Delivers deep chocolate flavor. Dutch-processed gives a richer color and smoother taste
- Baking soda: Helps the cookies rise properly and contributes to their chewy center
- Salt: Enhances all flavors especially the chocolate. Even if using salted butter a pinch is still beneficial
- Green food coloring: Creates that festive appearance. Gel food coloring provides vibrant color with minimal liquid
- Semisweet chocolate chips: Form the ganache topping. Choose good quality chips as they're a prominent flavor
- Oil: Makes the ganache spreadable and prevents it from cracking when set
Step-by-Step Instructions
- Prepare the Cookie Base:
- Begin by preheating your oven to 350°F and lining two baking sheets with parchment paper. This temperature creates the perfect environment for cookies with slightly crisp edges and chewy centers. The parchment prevents sticking and makes cleanup effortless.
- Cream Butter and Sugar:
- Beat the room temperature butter and granulated sugar for a full 3-4 minutes until noticeably lighter in color and fluffy in texture. This incorporates air which helps create that perfect cookie structure. Don't rush this step as it's crucial for texture.
- Add Wet Ingredients:
- Mix in the vanilla extract and room temperature egg until fully incorporated. The mixture should look smooth and glossy. Scrape down the sides of the bowl to ensure everything is evenly mixed.
- Incorporate Dry Ingredients:
- Add flour, cocoa powder, baking soda and salt, mixing just until a cohesive dough forms. Overmixing at this stage can activate too much gluten resulting in tough cookies. The dough should hold together easily without being overly sticky.
- Shape and Bake Cookies:
- Portion the dough into 16 equal balls about 1¾ inches in diameter. Space them evenly on prepared baking sheets allowing room for spreading. Bake for 8-10 minutes looking for that perfect balance of set edges but slightly glossy centers.
- Create Mint Frosting:
- While cookies cool completely, beat together powdered sugar, butter, milk, mint extract and green food coloring until smooth and fluffy. Adjust consistency with additional milk or powdered sugar as needed. The frosting should be thick enough to hold its shape but spreadable.
- Apply Frosting Layer:
- Spread an even layer of mint frosting on each completely cooled cookie. Place the frosted cookies in the freezer for at least 15 minutes. This freezing step is crucial as it sets the frosting and prevents it from melting when the warm ganache is applied.
- Prepare Chocolate Ganache:
- Combine chocolate chips and oil in a microwave-safe bowl. Heat in short intervals, stirring thoroughly between each until just melted. Be careful not to overheat as chocolate can seize. The oil creates a smoother, more pourable consistency.
- Apply Ganache Topping:
- Remove cookies from freezer and spoon ganache over each one, allowing it to spread naturally to the edges. The frozen frosting layer prevents the ganache from mixing with the green frosting, creating that beautiful layered effect.

The mint extract is truly the star ingredient in this recipe. I discovered through much experimentation that different brands vary drastically in potency. My family's preference leans toward a moderate mint flavor that complements rather than overwhelms the chocolate. I remember one Christmas when I accidentally doubled the mint extract, and my brother-in-law joked that eating the cookies felt like biting into a tube of toothpaste!
Storage Tips
These cookies require refrigeration due to the butter-based frosting. Store them in an airtight container with parchment paper between layers to prevent sticking. They'll maintain peak freshness for up to a week in the refrigerator.
For longer storage, these cookies freeze beautifully for up to two months. I recommend flash-freezing them on a baking sheet first, then transferring to a freezer bag with parchment between layers. This prevents them from sticking together and allows you to thaw just what you need.
When ready to serve from frozen, allow them to thaw in the refrigerator for several hours or at room temperature for about 30 minutes. The ganache may develop a slight white bloom if temperature changes are too dramatic, but this doesn't affect flavor.
Creative Variations
While the classic mint-chocolate combination is hard to beat, this versatile cookie base lends itself to numerous flavor variations. Replace mint extract with orange extract and add orange zest to the frosting for a chocolate-orange version reminiscent of those foil-wrapped chocolate oranges during the holidays.
For coffee lovers, try using coffee extract in place of mint and adding a teaspoon of espresso powder to the cookie base. The frosting can be tinted a light brown instead of green to signal the flavor change.
Almond extract creates a delightful marzipan-like flavor that pairs beautifully with the chocolate. Consider topping with sliced almonds before the ganache sets for added texture and visual appeal.
During the summer months, I often make these with strawberry extract and pink coloring for a chocolate-covered strawberry effect that's always a hit at backyard gatherings.

Serving Suggestions
These indulgent cookies deserve to be showcased properly. For an elevated dessert experience, serve slightly chilled alongside a scoop of vanilla ice cream. The temperature contrast and flavor combination are simply magical.
For holiday gatherings, arrange these cookies on a tiered serving platter alternating with other festive treats like snowball cookies or chocolate crinkles for a visually stunning presentation.
These cookies pair wonderfully with hot beverages. The chocolate and mint flavors complement both coffee and tea beautifully. For an extra special touch, serve with hot chocolate topped with whipped cream and crushed candy canes during the holiday season.
Consider using these cookies as the base for an ice cream sandwich in summer months. Vanilla or chocolate ice cream works beautifully between two cookies, though I recommend freezing the cookies first so they remain firm when the ice cream is added.

Yes, the food coloring is optional and only adds visual appeal. The mint flavor remains intact without it. You can also switch to another color for a personal touch.
- → Can I freeze the dough for later?
Absolutely! Form the dough into balls, freeze them on a baking sheet, then transfer to a freezer bag. Bake them from frozen, just adding a couple of extra minutes to the baking time.
- → How should I store these cookies?
Store cooled cookies in an airtight container in the fridge for up to a week or in the freezer for up to 2 months. Flash-freeze cookies to prevent sticking before placing in a bag or container.
- → What can I use instead of mint extract?
You can replace mint extract with other flavors like vanilla, peppermint, almond, or orange extract depending on your preferences.
- → Can I make these cookies dairy-free or gluten-free?
For dairy-free cookies, substitute butter with vegan margarine and use dairy-free chocolate. Gluten-free versions can be made with oat flour or gluten-free baking flour blends, ensuring no cross-contamination.
