2 sticks (16 tablespoons) unsalted butter, at cool room temperature
1 cup granulated sugar
½ cup crushed peppermint candy
36 peppermint kisses
Instructions
Adjust oven rack to lower-middle positions and heat oven to 375 degrees.
Mix egg, yolk, vanilla, and salt in a small bowl. Mix flour and baking powder in a medium bowl. Beat butter and sugar with an electric mixer until smooth and fluffy. Add egg mixture; mix on low speed until well incorporated. Add flour mixture; mix on low speed until dough forms. Beat in crushed peppermint.
Divide dough into thirty-six rounded tablespoon portions, rolling each into a ball. Working in batches, arrange 12 cookie dough balls on a large silpat- or parchment lined baking sheet. Bake until golden brown and puffed. Remove cookies from oven, gently pressing a peppermint kiss into each one. Transfer cookies to a wire rack to cool. Repeat with remaining dough balls and kisses. (Can be stored in a tin for a week or sealed and frozen up to 1 month.
