In a big bowl, use an electric mixer to smoothly combine butter and sugar. eggs and vanilla after mixing. Add the salt, baking soda, and flour. Dough should be covered and chilled for at least one hour or overnight.
The oven should be preheated to 400 degrees F (200 degrees C).
Sprinkle some flour on the work surface. Roll out the dough to a thickness of 1/4 to 1/2 inch. Use any cookie cutter to cut shapes. Place cookies on ungreased baking sheets 1 inch apart.
