Method
Make the dough
- In a large bowl, beat the softened unsalted butter and granulated sugar with an electric mixer on medium speed until light and creamy, about 2 minutes.
- Beat in the egg yolk and vanilla extract until combined, then mix in the all-purpose flour, unsweetened cocoa powder, and kosher salt on low speed just until a soft dough forms.
- Cover the bowl and refrigerate the dough for 30 minutes, until firm enough to shape.
Fill and bake
- Heat the oven to 350°F and line two large baking sheets with parchment paper.
- Scoop the dough into 24 portions, about 1 tablespoon each, and roll into balls; place 12 on each baking sheet, spacing them about 2 inches apart.
- Press a deep indentation into the center of each ball with your thumb, then fill each indentation with about 1/2 teaspoon cherry preserves.
- Bake one sheet at a time for 11 to 13 minutes, until the cookie edges are set; let the cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
Notes
Chill the dough until firm enough to shape so the cookies hold their thumbprint while baking. Store in an airtight container in the refrigerator for up to 5 days; freeze for up to 2 months. For a dairy-free swap, use dairy-free butter.
