CITRUS CRINKLE COOKIES

Steps:

• Whisk together the flour, baking powder and salt in a medium bowl.
• Combine the butter, brown sugar and 1/2 cup granulated sugar in the bowl of a stand mixer fitted with the paddle attachment. Beat on medium-high speed until light and fluffy, scraping the sides of the bowl as needed, about 2 minutes.
• Add the egg and beat until incorporated. Add the vanilla extract, citrus zest, citrus juice and food coloring and beat until incorporated. Decrease the mixer speed to low and add the flour mixture, beating until just combined. Cover the bowl and refrigerate until firm, at least 2 hours and up to overnight.
• Put the confectioners' sugar in a small bowl and the remaining 1/2 cup granulated sugar in another small bowl. Scoop tablespoons of the chilled dough and roll into balls. Toss each ball in the granulated sugar first, then in the confectioners' sugar, coating them very generously and thoroughly. Arrange the balls about 1 inch apart on 2 baking sheets (you should have 24 balls). Refrigerate for 20 minutes.
• Position the oven racks in the top and bottom thirds of the oven and preheat to 350 degrees F.
• Bake until the cookies spread, the tops crack and the edges are firm, 14 to 16 minutes. Let cool on the baking sheets for a few minutes, then transfer the cookies to a wire rack to cool completely. Store in an airtight container at room temperature for up to 3 days.
