Sugar Cookies

Preheat your oven to 375°F (190°C).

In a small bowl, stir together flour, sour cream, baking soda, and baking powder. Set aside.

In a large bowl, cream together the butter and sugar until smooth.

Beat in the egg and vanilla extract.

Gradually blend in the dry ingredients.

Roll rounded teaspoonfuls of dough into balls, and place onto ungreased cookie sheets.

Bake 8 to 10 minutes in the preheated oven, or until golden.

Let cool on wire racks.
