8 ounces unsalted butter
3/4 cup granulated sugar
1/4 teaspoon salt
1 1/2 teaspoons pure vanilla extract
1 large egg yolk
2 cups all-purpose flour

Directions:

1 
Beat the butter, sugar, salt and vanilla together until smooth and creamy.
2 
Mix in the egg yolk until well incorporated, scraping down the sides of the bowl at least once.
3 
Add the flour and mix just until incorporated.
4 
Scrape onto a lightly floured board and knead a few times, just until the dough smooths out.
5 
Turn onto a sheet of plastic wrap and roll into a log, wrap up and refrigerate for several hours or freeze.
6 
Before baking, preheat the oven to 325°F.
7 
Line your baking sheets with parchment.
8 
Slice the dough into slices about 1/8” thick and place them on the sheets about an inch apart (they won’t be spreading very much, but they need air room around each cookie).
9 
Bake until JUST beginning to turn golden around the edges, about 16-18 minutes.
