Chocolate-Mint Sandwich Cookies

• COOKIES:
• 1 cup all-purpose flour
• 6 tablespoons unsweetened cocoa
• 1/2 teaspoon baking soda
• 1/2 teaspoon salt
• 10 tablespoon (1 1/4 sticks) unsalted butter, at room temperature
• 1 cup sugar
• 1 large egg
• 1 teaspoon vanilla extract
• FILLING:
• 10 tablespoon (1 1/4 sticks) unsalted butter, at room temperature
• 1/2 cup confectioners' sugar
• Pinch of salt
• 1 1/2 cups Marshmallow Fluff
• 1/4 teaspoon peppermint extract
• Red and green food coloring

1. Make cookies: Mix flour, cocoa, baking soda and salt in a bowl. Using an electric mixer on medium speed, beat butter and sugar until light, about 3 minutes. Beat in egg and vanilla until smooth. Stir in flour mixture until just combined.
2. Divide dough in half. Shape each portion into a log about 9 inches long and 1 1/2 inches in diameter. Wrap in plastic; chill for at least 2 hours and up to 1 day (or freeze for up to 1 month).
3. Preheat oven to 350u0b0F. Place racks in upper and lower thirds of oven. Line 2 baking sheets with parchment. Slice dough into 1/4-inch-thick rounds (36 slices per log); place on baking sheets 2 inches apart. Bake until cookies are dry on top, about 10 minutes. Remove to a wire rack; cool. Repeat with remaining dough.
4. Make filling: Using an electric mixer on medium speed, beat butter, confectioners' sugar and salt until combined. Stir in Fluff and peppermint extract. Beat on high until light, about 3 minutes. Divide filling between 2 bowls, add red or green food coloring to each bowl; stir until evenly dyed. Sandwich 2 cookies with a teaspoon of filling. Repeat with remaining cookies and filling.
