Sour Cream Sugar Cookies

I got this recipe from my mother 36 years ago and have to say it is still my favorite sugar cookie recipe.

Cookie Dough

2 cups sugar
1 cup sour cream (I substitute Greek Yogurt all the time and it is perfect)
1 cup butter
2 eggs
1 tsp vanilla
1/2 tsp salt
1 tsp nutmeg
2 tsp baking soda
1 tsp cream of tarter
7 cups flour

Cream together sugar and butter; add sour cream , eggs and vanilla.  Blend well.  Gradually add dry ingredients until mixture forms a ball.  Roll out mixture on a lightly floured surface, cut out with cookie cutters.  Place cookies on cookie sheet and back at 350 degrees for 9-11 minutes.  

After cookies have cooled, dust with sugar or icing.

Cream Cheese Frosting

1/4 cup butter
1 tsp vanilla
3 cups powdered sugar
3 T milk
4 oz cream cheese, softened

Cream together softened butter and cream cheese; add remaining ingredients and beat until smooth.  Can tint with food coloring if desired.
