Soft Perfect Sugar Cookies

2 Cups sugar
1 Cup butter, softened
3 eggs
1 teaspoon vanilla
1 Cup sour cream
6 Cups flour
2 teaspoons baking soda
2 teaspoons baking powder
¼ teaspoon salt

1. In an electric or stand mixer, cream the sugar and butter. Add eggs, vanilla and sour cream until well combined. Slowly add in the flour, baking soda, baking powder and salt until well combined.
2. In 2 or 3 batches, place in between two sheets of plastic wrap and roll out to desired thickness. Keep in plastic wrap and chill for about 20 minutes for best results.
3. Once chilled, remove plastic wrap and cut into desired shapes. Bake at 350 degrees for 10-12 minutes depending on how thick you cut your cookies. Remove and let cool. Frost and decorate as desired.
