Ingredients: 250g flour, 3 egg yolks, 90g powdered sugar, 175g butter, 1 pinch salt.
Remember that the butter must be of refrigerator. In a bowl beat the egg yolks with sugar, then add the cold butter cut into small pieces, flour and salt. Mix well so that the butter is well mixed with the rest of the ingredients. Now put the mixture on a floured surface and quickly form a ball, then wind it up in plastic wrap. Leave it in the fridge for a few hours, best overnight. After the appropriate time, collect the dough from the fridge and with a knife cut a slice from the ball. With the help of a rolling pin roll out the dough thickness of about half a centimeter. Now you need a mold for cookies. If you do not have it you can also use the plastic cap of the plastic bottles of water and with the help of a toothpick draw the eyes and mouth. Have fun to create the most weird shapes and your snacks will be more fun. Now put the forms you created on a baking pan and bake in oven at 180°C for about 15 minutes.
