1 1/2 C sugar
1/2 C butter
1 C sour cream
2 tsp vanilla
5 C flour
2 tsp baking powder
1 tsp baking soda
1 tsp salt
Cream sugar and butter. Add eggs, sour cream and vanilla and beat well. Mix in dry ingredients.
Refrigerate for at least 1 hour.
Preheat oven to 350 degrees.
Roll out dough to 1/4 inch thick using plenty of flour. Don't overwork the dough, or cookies will be tough. Cut out cookies with cookie cutters.
Bake 7-8 minutes. Cookies are done if you touch one and it doesn't leave a finger mark. They will still be white on top. If you see any brown at all the cookies are done.
Let cool for 2 minutes then transfer to cooling rack.

I got this recipe from a ward cook book I bought at a Relief Society bazaar when I was 8.
