Ingredients

　　8 ounces (2 sticks) unsalted butter, softened

　　3/4 cup confectioners’ sugar

　　4 1/2 teaspoons pure vanilla extract

　　2 cups all-purpose flour

　　1 teaspoon salt

　　Put the butter and sugar in the bowl of an electric mixer fitted with the paddle attachment. Mix on medium speed until pale and fluffy, about 3 minutes; mix in the vanilla. Add the flour and the salt, and mix on medium-low speed until just combined and crumbly, about 15 seconds (do not overmix). Pat the dough into a disk, and wrap in plastic. Refrigerate at least 1 hour and up to 2 days, or freeze up to 1 month.
