Best Sugar Cookies Ever

I seriously have never had sugar cookies as good as these.  They are so soft and moist.  For St. Patrick's Day I colored them green.

Ingredients:
2 cups sugar
1 cup butter 2-3 eggs
1 cup sour cream
1 tsp. baking soda
1 tsp. vanilla
2 tsp. baking powder
1 tsp. salt
6-7 cups flour

Directions:

Mix baking soda into sour cream and set aside.  Cream butter and sugar, add eggs and cream together. Add remaining ingredients one at a time, beginning with sour cream mixture and ending with flour.  Bake at 350 degrees for 7-9 minutes.
