Ingredients
3/4 pound unsalted butter (3 sticks)
1 cup confectioner’s sugar
1/2 teaspoon salt
3 cups all-purpose flour
Preparation
Preheat oven to 350. Using a stand mixer fitted with a paddle attachment, beat the butter and sugar until smooth; 2 to 3 minutes. Sift the salt and flour, then add to the butter mixture, mixing until just combined.
Form the dough into a log about two-inches in diameter. Wrap the log with plastic wrap and chill for three hours or overnight. (Freeze for up to two months.)
Remove the dough from the refrigerator, remove the plastic wrap, and slice the dough into 1/4-inch disks. Place on an ungreased baking sheet one-inch apart and bake until the bottoms of the cookes just turn golden; about ten minutes, turning the sheet 180 degrees after five minutes. Remove from the oven and cool completely on a rack.
