- 1 stick unsalted butter, softened
- 1 cup all-purpose flour
- 1/3 cup confectioners' sugar
- 1/2 teaspoon pure vanilla extract
Preheat oven to 300°.
In mixing bowl, cream butter. Add flour, sugar and vanilla; mix just to combine (chill 10 minutes in refrigerator).
Pat into an 8-inch round cake pan and with a pairing knife, lightly score into 8 wedges; crimp edge with a floured fork. Bake until firm and slightly browned, 30 to 35 minutes (drape with foil if browning too quickly). Cool completely. Turn out of pan; slice wedges with a serrated knife.
