Instructions
Cream together salted butter and sugar until light and fluffy.
Add in the egg yolks one at a time, mixing well after each addition.
Sift in flour and baking powder, mix until soft dough forms.
Divide dough into two pieces, wrap in plastic and chill for at least one hour.
Preheat oven to 325°F (165°C) and prepare a baking sheet with parchment paper.
Roll out one dough disk on floured surface to ¼-inch thick and cut rounds.
Place cut cookies on baking sheet and brush tops with egg wash.
Use fork to make crosshatch pattern if desired.
Bake for 18–22 minutes until golden brown. Let cool slightly before transferring to rack.
Repeat egg wash and baking process for second dough portion.
Notes
Dough can be made ahead and chilled for up to 5 days. Once baked, cookies store well in an airtight container for up to 4 days. For best texture, avoid overbaking.
