Ingredients
Makes about 30–36 thin cookies
Cookie Dough
- 1/2 cup (115g) unsalted butter, softened
- 3/4 cup (150g) granulated sugar
- 1 large egg
- 1 teaspoon vanilla extract
- 1/2 teaspoon peppermint extract (adjust to taste)
- 1 cup (125g) all-purpose flour
- 1/3 cup (35g) unsweetened cocoa powder
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 2 tablespoons milk (as needed for a smoother batter)
Optional Chocolate Dip (Recommended)
- 1 cup (170g) semi-sweet chocolate chips or chopped chocolate
- 1 teaspoon coconut oil (optional, for smoother dipping)
Optional garnish:
- Crushed peppermint candies or flaky sea salt
Preparation Time
- Prep time: 15 minutes
- Chill time: 30 minutes
- Bake time: 8–10 minutes
- Total time: About 55 minutes
Step-by-Step Instructions
Step 1: Mix the Wet Ingredients
In a bowl, cream butter and sugar until light and fluffy. Beat in the egg, vanilla, and peppermint extract.
Step 2: Add the Dry Ingredients
In a separate bowl, whisk flour, cocoa powder, baking soda, and salt. Add dry ingredients to wet and mix until combined.
If the dough feels too stiff, add milk 1 tablespoon at a time until it’s spreadable.
Step 3: Chill for Better Thin Cookies
Cover and chill dough for 30 minutes. This keeps the cookies from spreading too fast and helps them bake evenly.
Step 4: Shape and Flatten
Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
Scoop small teaspoons of dough and place them 2 inches apart. Flatten very thin with the bottom of a glass or spoon (thin = crispy!).
Step 5: Bake
Bake for 8–10 minutes until the edges look set. The cookies will firm up as they cool.
Step 6: Cool
Let cookies cool on the pan for 5 minutes, then transfer to a rack to cool completely.
Step 7: Dip (Optional)
Melt chocolate (with coconut oil if using). Dip half of each cookie into melted chocolate and place on parchment. Sprinkle with crushed peppermint if desired. Let set.
