Sift the flour. In a food processor add the flour, pinch of salt and the COLD butter cut in cubes. It is very important to use cold butter, not room temperature.
Transfer the buttery flour mix in a big bowl and add the orange zest, the orange extract, the vanilla extract, the egg yolks and the powdered sugar (sifted).
Start mixing using a fork and when the yolks will be nicely mixed keep working the mix with your hands. The warmth of your hands will slowly melt the butter in the mix so that the dough will nicely come together.
Transfer the dough on a flat surface and keep kneading it with your hands in order to obtain a uniform, elastic dough. It will take 5 min.
Wrap the dough in some parchment paper and store it in the refrigerator for 30 minutes to get cold and firm.
Unwrap the dough and using a second foil of parchment paper on top roll the dough with a rolling pin and flatten it into a 1/2 inch layer. Have fun using any cookie cutter shape that you like.
Place the cut out cookies on a baking sheet lined with parchment paper and bake the cookies in the preheated oven at 400F/200C for 10 minutes. Enjoy!!!
