Chocolate Peppermint Sandwich Cookies (Printable)

Chocolate sandwich cookies with creamy peppermint filling - minty, festive, and perfect for sharing.

# What You'll Need:

→ Chocolate Cookie Dough

01 - 1 cup all-purpose flour
02 - ½ cup unsweetened cocoa powder
03 - ½ teaspoon baking soda
04 - ¼ teaspoon salt
05 - ½ cup unsalted butter, softened
06 - ¾ cup granulated sugar
07 - 1 large egg
08 - 1 teaspoon vanilla extract

→ Peppermint Cream Filling

09 - ½ cup unsalted butter, softened
10 - 1½ cups powdered sugar, sifted
11 - 2 tablespoons heavy cream or milk
12 - ½ teaspoon peppermint extract
13 - Pinch of salt
14 - A few drops of green or red food coloring (optional)

# How-To Steps:

01 - Preheat oven to 350°F. Line two baking sheets with parchment paper and set aside.
02 - In a medium bowl, whisk together the all-purpose flour, cocoa powder, baking soda, and salt until evenly distributed.
03 - In a large mixing bowl, beat the softened butter and granulated sugar together using an electric mixer until light and fluffy, about 2 to 3 minutes. Add the egg and vanilla extract, beating until fully incorporated.
04 - Gradually add the dry ingredient mixture to the creamed butter mixture, mixing on low speed until just combined. Avoid overmixing to keep the cookies tender.
05 - Roll tablespoon-sized portions of dough into balls, flatten slightly, and arrange them 2 inches apart on the prepared baking sheets. Bake for 8 to 10 minutes until the cookies are set. Allow them to cool on the baking sheets for 2 minutes, then transfer to a wire rack to cool completely.
06 - In a mixing bowl, beat the softened butter until smooth and creamy. Add the sifted powdered sugar, heavy cream, peppermint extract, salt, and food coloring if using. Beat on medium speed until the filling is light and fluffy, about 2 minutes.
07 - Spread or pipe approximately 1 tablespoon of peppermint filling onto the flat side of half the cooled cookies. Top each with a remaining cookie, flat side down, pressing gently to form even sandwiches.
08 - Refrigerate the assembled cookies for 15 minutes to allow the filling to firm up before serving. For a festive finish, roll the edges of each sandwich in crushed peppermint candies.

# Expert Advice:

01 -
  • The contrast between the soft, fudgy cookie and the cool peppermint cream filling is genuinely addictive and hard to stop eating.
  • They look like something from a bakery window but come together with basic pantry ingredients and zero fancy equipment.
02 -
  • Overbaking is the fastest way to ruin these because the cookies go from perfectly fudgy to dry in a matter of minutes, so pull them when the centers still look slightly soft.
  • Sifting the powdered sugar for the filling is the difference between smooth, elegant cream and a grainy texture that nobody wants to bite into.
03 -
  • Use a cookie scoop instead of a spoon for uniform balls so every sandwich matches and they bake evenly across the tray.
  • Swapping peppermint extract for vanilla in the filling gives you a classic cream sandwich that pairs beautifully with a cup of coffee any time of year.
