Method
Make the dough
- Heat the oven to 350°F.
- Line a large baking sheet with parchment paper.
- In a large bowl, beat the softened butter, 2/3 cup granulated sugar, and brown sugar until light and creamy, about 2 minutes.
- Beat in the egg and vanilla until combined.
- In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt.
- Mix the dry ingredients into the butter mixture just until no dry streaks remain.
- Cover the dough and chill it for 30 minutes.
Shape and bake the cookies
- Put the remaining 1/4 cup granulated sugar in a small bowl.
- Scoop the dough into 1-tablespoon portions, roll each portion into a ball, then roll it in the sugar.
- Arrange 12 balls on the prepared baking sheet, spacing them about 2 inches apart.
- Bake for 8 to 10 minutes, until the tops are cracked and the edges look set.
- Bake the remaining dough in batches.
Add the topping
- Immediately press one unwrapped peppermint chocolate into the center of each hot cookie.
- Let the cookies cool on the baking sheet for 5 minutes.
- Transfer the cookies to a rack to cool completely.
Notes
For neat, even cookies, scoop level 1-tablespoon portions. Store in an airtight container in the refrigerator for up to 5 days; baked cookies can be frozen. For a dairy-free swap, use plant-based butter and dairy-free peppermint chocolates.
