Surprise kiss cookies have a hidden chocolate kiss inside! These cookies are the perfect dessert to make for Valentine’s Day and Christmas cookie swaps!
In a large bowl of a stand mixer (or using a hand mixer), combine butter, sugar and vanilla until light and fluffy, about 2 minutes. Add flour and walnuts. Stir until well blended.
Cover dough and chill in the refrigerator for 2 hours.
Measure about 1 tablespoon of dough and shape it around one chocolate kiss and roll it to make a ball (cover chocolate completely). Place dough balls 2 inches apart on prepared baking sheet.
Allow cookies to cool on the baking sheet for 5 minutes. While the cookies are still warm, roll them in confectioners' sugar. Set on a wire rack.
