Ingredients

Scale
  • 2 ½ cups all-purpose flour (or substitute almond flour for gluten-free)
  • 1 teaspoon baking powder
  • ½ teaspoon baking soda
  • ¼ teaspoon salt
  • ¾ cup unsalted butter, softened
  • 1 cup granulated sugar
  • 1 large egg, room temperature
  • 1 teaspoon pure vanilla extract
  • ½ teaspoon peppermint extract
  • 2 tablespoons whole milk (or dairy-free milk)
  • Green food coloring (optional)
  • 8 oz cream cheese, softened
  • ½ cup unsalted butter, softened
  • 3 cups powdered sugar, sifted
  • ½ teaspoon peppermint extract
  • 12 tablespoons milk or cream
  • Green food coloring (optional)

Instructions

  1. Preheat oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone mats.
  2. In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.
  3. In a large bowl, beat softened butter and granulated sugar until creamy and light, about 3-4 minutes.
  4. Add egg, vanilla extract, and peppermint extract to the butter-sugar mixture. Beat until combined.
  5. Gradually add dry ingredients to wet mixture, alternating with milk. Mix just until combined. Add green food coloring if desired.
  6. Drop dough balls about 2 inches apart on prepared baking sheets using a tablespoon or cookie scoop. Flatten each ball to about ½ inch thickness.
  7. Bake for 10-12 minutes until edges are set and centers look slightly underbaked. Remove from oven.
  8. Let cookies cool on baking sheets for 5 minutes, then transfer to cooling racks to cool completely.
  9. While cookies cool, beat cream cheese and softened butter until smooth and fluffy, about 3-5 minutes.
  10. Gradually add powdered sugar, mixing well after each addition. Add peppermint extract and milk or cream to reach desired consistency. Add green food coloring if desired.
  11. Once cookies are completely cool, spread or pipe minty frosting generously on top. Optionally, sprinkle with crushed peppermint candies or green sugar crystals.
  12. Allow frosting to set at room temperature for about 30 minutes before serving.

Notes

Use room temperature ingredients for best results. Do not overmix dough to avoid tough cookies. Watch baking time closely to keep cookies soft and chewy. Use fresh peppermint extract for best flavor. Adjust frosting consistency with milk and chill if needed. Chill dough 20-30 minutes if kitchen is warm to prevent spreading. For dairy-free version, substitute coconut oil, dairy-free cream cheese, and milk alternatives. Cookies can be frozen unfrosted or frosted (flash freeze first) for up to 3 months.
