These Chocolate-Mint Sandwich Cookies will be a hit for kids of all ages. A combination of Marshmallow Fluff, powdered sugar, and peppermint extract creates the creamy filling between these chocolate sandwich cookies. For a festive touch, tint the filling with red and green food coloring.

How to Make It

Step 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.

Step 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).

Step 3

Preheat oven to 350ºF. 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.

Step 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.

Loved these cookies! The only change I made was to double the peppermint extract. A few more tips: spray vegetable oil cooking spray on a spatula and measuring cup to make it easier to work with the sticky marshmallow fluff, and chill the dough a bit before rolling it into logs. I cheated and used the freezer. :) They set up nicely if you put them in the fridge when you are done. These got RAVE reviews from my kids and family on Thanksgiving, and I'm making them for gifts for Xmas!
