If you are a fan of Andes Mints or Thin Mints, these Chocolate Mint Cookies are about to become your new obsession. This recipe is a triple-threat dessert, featuring a rich and chewy chocolate cookie base, a thick layer of silky mint buttercream, and a decadent chocolate ganache finish. They are a literal “showstopper” on any holiday platter and the perfect St. Patrick’s Day chocolate cookies thanks to their vibrant green center.
The brilliance of these mint chocolate cookies is the texture.

Ingredients
The Chocolate Cookies
- ½ cup Unsalted Butter, softened
- 1 cup Granulated Sugar
- 1 tsp Vanilla Extract
- 1 Large Egg
- 1 ¼ cups All-purpose Flour
- ⅓ cup Unsweetened Cocoa Powder
- ½ tsp Baking Soda
- ¼ tsp Salt
The Mint Frosting
- 1 ½ cups Powdered Sugar
- ½ cup Unsalted Butter, softened
- 1 Tbsp Milk
- ½ to 1 tsp Mint Extract (adjust to taste)
- Green Gel Food Coloring
The Ganache
- ¾ cup Semi-sweet Chocolate Chips
- 1 Tbsp Oil (Vegetable or Coconut)
Instructions
1. Bake the Cookies
Preheat oven to 350°F (175°C). Cream the butter and sugar for 3–4 minutes until smooth. Beat in the egg and vanilla. Mix in the flour, cocoa powder, baking soda, and salt. Roll into 16 balls and bake for 8–10 minutes. Let cool completely.
2. Frost the Cookies
Whisk together the powdered sugar, butter, milk, mint extract, and green food coloring until light and fluffy. Spread an even layer of frosting onto each cooled cookie.
3. The “Flash Freeze” Trick
Place the frosted cookies in the freezer for at least 15 minutes. This is the secret to getting a perfect ganache layer—the cold frosting keeps the warm chocolate from running off the edges.
4. Top with Ganache
Melt the chocolate chips and oil in the microwave in 30-second increments until smooth. Spoon the warm ganache over the frozen cookies, spreading it gently to the edges.
5. Set and Serve
Let the cookies sit at room temperature until the ganache is firm, or refrigerate if you prefer a snappier chocolate shell.
Expert Tips for Success
- Don’t Overbake: The center of the cookie should still look slightly glossy when you pull them out; they will firm up as they cool to create that perfect chewy texture.
- Peppermint vs. Mint: Be sure to use Mint Extract (which tastes like Andes mints) rather than Peppermint Extract if you want that classic holiday flavor.
- Room Temp Ingredients: Ensure your butter and egg are at room temperature to achieve a smooth, emulsified dough and frosting.
- Oil in Ganache: The tablespoon of oil is what makes the chocolate ganache spreadable and prevents it from cracking when you bite into the cookie.

Variations
- Dark Chocolate Mint: Use dark cocoa powder and dark chocolate chips for a more intense, less sweet flavor profile.
- White Chocolate Mint: Swap the ganache for melted white chocolate tinted with a drop of green food coloring.
- Grasshopper Cookies: Add a tablespoon of Crème de Menthe to the frosting for a boozy, adult-only version.
- Cookie Bars: Instead of individual cookies, press the dough into a 9×9 pan and layer the frosting and ganache on top, then slice into squares.
FAQ: Chocolate Mint Cookies
Q: Can I freeze the cookie dough? A: Yes. Roll the dough into balls and freeze them. You can bake them straight from the freezer; just add 1–2 minutes to the total bake time.
Q: How do I store these? A: Store in an airtight container in the refrigerator for up to 1 week. They can also be frozen for up to 2 months.
Q: Why is my ganache sliding off? A: This usually happens if the cookies weren’t chilled enough before adding the chocolate. Make sure the frosting is firm to the touch (15+ minutes in the freezer) before topping.
Q: Can I use peppermint extract? A: Yes, but the flavor will be more like a candy cane than a chocolate mint candy. Both are delicious, but “Mint Extract” is the classic choice for this specific recipe.
