Ingredients

2/3 cup plus 1 tablespoon all-purpose flour 

1/4 teaspoon salt 

7 tablespoons unsalted butter, softened 

3/4 cup confectioners' sugar, sifted 

2 large eggs 

2 teaspoons pure vanilla extract 

Preparation

Preheat oven to 375 degrees. Sift together flour and salt in a small bowl; set aside.

Put butter into the bowl of an electric mixer fitted with the paddle attachment; mix on medium speed until smooth and creamy. Mix in sugar. Add eggs, 1 at a time, mixing well after each addition. Mix in vanilla. Fold in flour mixture.

Transfer batter to a pastry bag fitted with a 3/8-inch plain round tip (such as Ateco #804). Pipe 2-inch lengths, about 3/4 inch wide (the ends should be slightly wider than the center), onto baking sheets lined with parchment, spacing about 1 inch apart. (Batter should be refrigerated if not being used immediately.)

Bake until just golden around edges, 10 to 12 minutes. Let cool on sheets 3 minutes. Transfer to wire racks; let cool completely. Cookies can be stored in airtight containers up to 3 days.
