In the bowl of a stand mixer, cream together the butter and sugar until light and fluffy.

In a separate bowl, mix the flour, salt, and baking soda with a fork. Set aside. 

Add eggs to the mixture one at a time, and mix to combine. Add vanilla, and mix to combine, scraping down the sides of the bowl as needed. 

Add the dry ingredients (flour, salt, and baking soda) to the bowl of the stand mixer, and mix to combine. 

Separate dough into 2-3 balls, wrap in plastic wrap, and chill in the refrigerator for 2-3 hours, or until needed. 

Preheat oven to 350 degrees F. Line baking sheets with parchment paper for easy cleanup.

To make cookie cutouts, dust the counter generously with flour. Using a rolling pin, roll the dough out flat, about 1/4" thick. Sprinkle your favorite cookie cutters with flour, and press into the dough. Gently transfer the cookie cutout to the baking sheet. 

Bake cookies at 350 degrees F for 8-10 minutes. Cool cookies completely before decorating!
