Sugar Cookies

2 cups butter or margarine
2 cups sugar
4 eggs
2 tsp. vanilla
3 tsp. baking powder
1 tsp. salt
5 cups flour

Cream butter, sugar, eggs and vanilla. Add baking powder, salt and flour. Refrigerate dough overnight. Keep dough in fridge when not in use. Roll dough to desired thickness. Use flour as necessary so the dough is a little sticky. Cut out shapes with cookie cutters and place on large greased cookie sheet. Bake at 350 degrees for 10-15 minutes, or until lightly browned.
