Sweet Potato-Marshmallow Sandwich Cookies encompass all the flavors of the holiday season. These creamy, buttery cookies make well-received gifts, too.

Ingredients

  • 1 cup butter, softened
  • 3/4 cup powdered sugar
  • 3/4 cup canned sweet potato puree
  • 2 teaspoons vanilla extract
  • 2 1/2 cups all-purpose flour
  • 1/4 teaspoon baking powder
  • 1/8 teaspoon salt
  • 1 teaspoon freshly grated nutmeg
  • 3/4 teaspoon ground cardamom
  • 1/2 teaspoon ground ginger
  • 1/2 teaspoon ground cinnamon
  • Wax and parchment paper
  • 1 tablespoon Demerara sugar
  • 1/2 cup marshmallow crème
  • 1/2 cup butter, softened
  • 2 cups powdered sugar
  • 1 1/4 teaspoons meringue powder
  • 1 teaspoon vanilla extract

How to Make It

  1. Beat butter at medium speed with an electric mixer until creamy. Gradually add 3/4 cup powdered sugar, beating until smooth. Stir in 3/4 cup canned sweet potato puree and 2 tsp. vanilla until blended.

  2. Stir together flour and next 6 ingredients. Gradually add flour mixture to butter mixture, beating at low speed until blended.

  3. Divide dough in half; flatten each into a disk. Roll each disk to 1/4-inch thickness between 2 sheets of wax paper. Transfer dough, in wax paper, to a baking sheet; chill 1 hour.

  4. Preheat oven to 350°. Working with 1 portion of dough at a time, remove top wax paper; cut with a 2-inch round cutter, rerolling dough scraps once. Place 1 inch apart on parchment paper-lined baking sheets; sprinkle with Demerara sugar.

  5. Bake at 350° for 12 to 14 minutes or until edges are golden. Cool on baking sheets 1 minute; transfer to wire racks. Cool completely.

  6. Beat marshmallow crème and softened butter with a heavy-duty electric stand mixer at medium speed 2 minutes or until smooth; gradually add 2 cups powdered sugar. Add meringue powder, and beat at high speed 2 minutes or until fluffy. Stir in 1 tsp. vanilla extract. Spread about 2 tsp. mixture between cooled shortbread rounds to form sandwiches. Store in airtight containers.
