Method
Make the dough
- In a large bowl, whisk together the cocoa powder, oil, and granulated sugar until smooth.
- Whisk in the eggs one at a time, then whisk in the vanilla and peppermint extracts.
- In a medium bowl, whisk together the flour, baking powder, and salt, then stir the dry mixture into the cocoa mixture just until no dry streaks remain.
- Cover the bowl and refrigerate the dough for at least 4 hours or overnight, until firm.
Coat and bake
- Heat the oven to 350°F and line two large baking sheets with parchment paper.
- Put the powdered sugar in a shallow bowl.
- Scoop the dough into 1-tablespoon portions, roll each into a ball, coat generously in powdered sugar, and place 2 inches apart on the baking sheets.
- Bake one sheet on each oven rack for 10 to 12 minutes, switching the sheets’ rack positions and rotating them front to back halfway through, until the cookies are cracked and the edges are set but the centers still look soft.
- Let the cookies rest on the baking sheets for 5 minutes.
- Transfer them to a wire rack to cool completely.
Notes
Chill the dough until firm so the portions are easier to roll and coat. Store the cookies in an airtight container at room temperature for up to 5 days; they freeze well for up to 3 months. For a gluten-free option, use a cup-for-cup gluten-free baking blend in place of the all-purpose flour.
