Homemade Lemonades Cookies

Instructions

• Preheat the oven to 300 degrees F (150 degrees C). Line 2 baking sheets with parchment paper.
• Combine cold butter, white sugar, lemon zest, salt, and vanilla in a bowl; slowly stir together until butter has softened somewhat and ingredients come together.
• Add flour to the butter mixture. Flour your hands and, using fingertips, rub mixture together until buttery crumbs form, 1 to 2 minutes. Press mixture into a ball.
• Transfer dough to lightly floured work surface and press into a 1/2-inch- thick disk. Cover with a piece of plastic wrap. Roll dough to 1/4-inch thickness.
• Cut dough with a 2-inch round cutter, rerolling scraps if needed. Arrange cutouts 1 inch apart on the prepared cookie sheets. Use a sharp knife to score 1/4- to 1/2-inch decorative lines around the outer edges of each cookie, cutting toward the center. Use a toothpick or skewer to poke small holes at the end of every other line near the center.
• Bake in the preheated oven until light brown around the edges, 22 to 25 minutes. Transfer to a wire rack to cool completely.
• For glaze, stir together powdered sugar and lemon juice; brush a thin layer over each cookie. Let stand until set, about 30 minutes.
