Ingredients
2 cups confectioners' sugar, sifted
3 tablespoons to 1/4 cup milk
1/4 teaspoon vanilla extract
1 1/2 sticks unsalted butter (6 ounces), room temperature
1/2 cup granulated sugar
1 large egg yolk
1 3/4 cups unbleached all-purpose flour
1/2 teaspoon kosher salt
1 teaspoon pure peppermint extract
1 tablespoon milk
Red gel-paste food coloring, for glazing (optional)
Preparation
Glaze: Whisk together confectioners’ sugar and milk until smooth. Whisk in vanilla. Glaze can be stored at room temperature, with plastic wrap pressed directly on surface, up to 3 days; whisk before using. (Makes 2 cups.)
Cookies: Preheat oven to 350 degrees. Beat butter with granulated sugar on medium-high speed until light and fluffy, about 3 minutes. Add yolk, flour, salt, peppermint extract, and milk; beat to combine.
Fill a cookie press with dough and fit with a wreath disk. Press cookies directly onto unlined baking sheets. Bake, rotating sheets halfway through, until just golden on edges, 12 to 14 minutes. Transfer sheets to a wire rack; let cool completely.
Working in batches, add a drop of food coloring to a small amount of glaze (about 1/4 cup); use a toothpick to swirl a tiny bit. Dip tops of cookies in glaze, then turn glaze-sides up and place on a wire rack set over a rimmed baking sheet to catch drips to set. (As you dip, colors will become more combined and no longer look like swirls; change to fresh glaze at this point.) For additional “swirls,” dip a toothpick in red glaze and drizzle over cookies. Cookies can be stored in an airtight container at room temperature up to 3 days.
