Ingredients
>
2 cups all-purpose flour
>
2/3 cup confectioners' sugar
>
1 cup (2 sticks) salted butter, cut up and softened
>
1/2 cup red or green sprinkles or coarse decorating sugar
Steps
1
In a food processor, pulse the flour and sugar together. Add the butter and pulse until dough just comes together, stopping and stirring occasionally.
2
Transfer half of dough to a large sheet of plastic wrap. Shape into a 12-inch log and wrap tightly in plastic, smoothing into even log. Repeat with remaining dough and another sheet of plastic wrap. Refrigerate at least 30 min., or up to overnight.
3
Preheat oven to 350°F. Line a large cookie sheet with parchment.
4
Place the sprinkles in a wide shallow dish. Remove 1 log from refrigerator and unwrap. Lightly brush with cold water, then roll log in sprinkles to cover sides, pressing to adhere. Cut dough into ¼-inch-thick slices. Arrange on lined pan, spacing 1 inch apart.
5
Bake 10–12 min., until golden brown on bottoms. Cool completely on wire rack. Repeat baking and cooling with remaining dough and sprinkles. To store, place in a sealed container at room temperature for up to 2 weeks.
Tips
Similar to flour, confectioners’ sugar can be measured in different ways, resulting in very different textures. For the most accurate results, weigh the confectioners’ sugar (⅔ cup = 75g).
