Ingredients
- 1 stick of unsalted butter room temp (1/2 cup)
- 1 cup of sugar
- 1 tsp vanilla extract
- 1 egg
- 1 1/4 cups of flour
- 1/3 cup of unsweetened cocoa powder
- 1/2 tsp baking soda
- 1/4 salt
- 1/2 cup of butter room temp
- 3 cups of powdered sugar
- 1 tbsp milk
- Green food coloring
- 1 tsp peppermint extract
- 1 cup of semisweet chocolate chips
- 1 tbsp vegetable oil
Instructions
- Preheat the oven to 350° and line a large baking sheet with parchment paper. (or two baking sheets) in a large bowl add the butter and sugar and beat using a hand mixer until the mixture becomes smooth and creamy. Add the vanilla and egg and beat until combined.
- Add in the flour, cocoa powder, baking soda and salt to the bowl and beat again until everything becomes mixed together and a dough forms. Make sure to scrape down the walls with a spoon to get all the dry ingredients mixed together.
- Roll into 1 tbsp sized balls and place them on the baking sheet. About 1-2 inches apart. Bake for 10 minutes. Let cool for 20 minutes after removing them from the oven. While they are cooking make the frosting.

Pro Tips for Perfect Thin Mint Cookies
- Use a Cookie Scoop: A 1 tablespoon scoop keeps every cookie the same size, which means they all bake in exactly 10 minutes. Uneven balls give you some overdone and some raw.
- Don't Overbake: Slightly underdone centers at the 10 minute mark are the secret to soft cookies. If they look fully done in the oven, they'll be dry by the time they cool.
- Cool Completely Before Frosting: Even slightly warm cookies will melt the buttercream into a glaze. Twenty minutes minimum, and don't rush it.
- Go Easy on the Peppermint: One teaspoon gives you bold thin mint flavor. If you're mint-cautious, start with 1/2 teaspoon, taste the frosting, and add more from there. You can always add but you can't take away.
- Gel Coloring Wins: Gel food coloring gives you vibrant green without thinning the frosting. Liquid coloring works too, just account for the extra moisture with a bit more powdered sugar.
- Mise en Place the Drizzle: Have your bag, scissors, and bowl ready before the cookies leave the freezer. The colder the frosting when the chocolate hits it, the cleaner the set.
