Butter Cookies are so delicious and can be served up at many occasions or just because some one is special.
Mix flour, sugar and salt, butter, mix until butter breaks down into small pieces.
Increase the speed to medium and mix until the flour and butter form small clumps.
Add the egg yolks and vanilla and mix at low speed until the dough comes together in a few large clumps.
Pat the cookie dough into two 1/2-inch-thick disks, wrap them in plastic and refrigerate until chilled but not firm, about 30 minutes.
Line 2 large rimmed baking sheets with parchment paper.
Working on a lightly floured surface, 1 disk at a time, roll out dough to 1/8 inch thick.
Using 3- to 4-inch cookie cutters, but any shape can be created. Cut the dough into shapes and transfer to the prepared baking sheets.
Bake for 10 – 15 mins until lightly golden, not brown.
Cool for 5 mins on tray before transferring for further cooling on wire rack.
