These fudgy chocolate mint sandwich cookies are ready in 30 minutes with simple pantry ingredients. A cool mint buttercream filling between two soft, brownie-like chocolate cookies makes them the perfect Halloween treat.

Ingredients

Scale
  • 1 cup unsalted butter, softened
  • 1 cup granulated sugar
  • 1 large egg, room temperature
  • 1 teaspoon vanilla extract
  • 1 ½ cups all-purpose flour
  • ¾ cup unsweetened cocoa powder (Dutch-process preferred)
  • ½ teaspoon baking soda
  • ¼ teaspoon salt
  • ½ cup unsalted butter, softened (for filling)
  • 2 cups powdered sugar
  • 2 tablespoons heavy cream (or whole milk)
  • ¾ teaspoon peppermint extract
  • 2–3 drops green food coloring (optional)
  • A tiny pinch of salt

Instructions

  1. Preheat oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone mats.
  2. In a large mixing bowl, beat softened butter and granulated sugar together until light and fluffy, about 2-3 minutes.
  3. Add egg and vanilla extract, beat until well combined.
  4. In a separate medium bowl, whisk together flour, cocoa powder, baking soda, and salt until no lumps remain.
  5. Gradually add dry ingredients to wet mixture, mixing on low speed until just combined. Do not overmix.
  6. Scoop tablespoon-sized balls of dough and place 2 inches apart on prepared baking sheets.
  7. Bake for 8-10 minutes until puffy and slightly cracked on top. Cookies will look underdone in center.
  8. Let cookies cool on baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
  9. For the mint buttercream: Beat softened butter until smooth and creamy. Gradually add powdered sugar, beating on low speed.
  10. Add heavy cream, peppermint extract, green food coloring (if using), and a tiny pinch of salt. Beat on medium-high speed for 2-3 minutes until light and fluffy.
  11. Once cookies are completely cool, pair them by size. Spread or pipe 1-2 teaspoons of buttercream onto the flat side of one cookie, then gently press another cookie on top.
  12. Repeat with remaining cookies to make about 18-20 sandwich cookies.

Notes

Make sure butter is truly softened but not melted. Use Dutch-process cocoa for deeper flavor. Start with ½ teaspoon peppermint extract and adjust to taste. Let cookies cool completely before filling to prevent buttercream from melting. Chill filled cookies for 10 minutes before serving for best texture.
