Flour should be weighed for the most reliable results
2 ½ cups flour (15oz/424 grams). Don’t sift it -- scoop it
½ teaspoon salt
¾ cup (1 ½ sticks) unsalted butter, room temperature
I cup sugar, minus 1 ¾ tablespoons (6.8oz/198 grams)
1 medium to large egg
1 ½ teaspoon vanilla extract
Beat the butter on med-high speed until creamy. Scrape down sides of bowl when needed. Reduce speed and slowly add sugar. Return to med-high speed and beat until creamy (note: mixture lightens when creamed).
Reduce speed to medium and add the egg and vanilla. Mix until well incorporated. Scrape down sides of bowl when needed. In a separate bowl combine the flour and salt together with a whisk or fork.
Divide dough into 2 portions. Form each into disk shape and wrap in plastic wrap. Refrigerate for at least 2 hours or freeze for later use. (If frozen, best when used within 6 months.)
Bake cookies at 350˚F on parchment paper until lightly browned on edges. Turn cookie sheet about halfway through baking time. Times vary according to size and thickness of cookie.
