These Classic Homemade XOXO Sandwich Cookies feature a tender buttery vanilla cookie with a creamy vanilla filling, perfect for any occasion and easy to make.
Chill dough for at least 1 hour to prevent spreading and maintain shape. Use room temperature eggs for smooth mixing. Sift powdered sugar for smooth filling. Bake until edges just turn golden for tender cookies. If dough is sticky after chilling, lightly flour surface when rolling. Stamp cookies right before baking for best imprint definition.
