Ingredients

Scale
  • 1 cup all-purpose flour
  • 1/2 cup unsweetened cocoa powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1/2 cup unsalted butter, softened
  • 1/2 cup brown sugar
  • 1/4 cup granulated sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • Peppermint Filling:
  • 1/4 cup unsalted butter, softened
  • 1 cup powdered sugar
  • 1/2 teaspoon peppermint extract
  • 1 tablespoon milk (more as needed)
  • Crushed peppermint candies or candy canes for garnish (optional)

Instructions

  1. Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.
  2. In a medium bowl, whisk together flour, cocoa powder, baking soda, and salt.
  3. In a large bowl, cream butter, brown sugar, and granulated sugar until light and fluffy. Beat in egg and vanilla.
  4. Gradually add dry ingredients to wet, mixing until just combined.
  5. Scoop dough by rounded teaspoons onto prepared baking sheet. Flatten slightly with your fingers or the bottom of a glass.
  6. Bake for 8–10 minutes or until edges are set. Let cool completely on a wire rack.
  7. To make the filling, beat butter until creamy. Add powdered sugar, peppermint extract, and milk. Beat until smooth and fluffy, adjusting consistency with more milk if needed.
  8. Spread or pipe peppermint filling onto the flat side of half the cookies. Top with the remaining cookies to form sandwiches.
  9. Roll edges in crushed peppermint candies if desired. Store in an airtight container.

Notes

  • Chill dough for 20 minutes if it becomes too soft to handle.
  • Use gel food coloring in the filling for a festive touch.
  • Store cookies at room temperature for up to 4 days or refrigerate for longer freshness.
