Peanut Butter Cookies

I think this is the best peanut butter cookie recipe I've tried so far (and I've tried many).

1 stick butter, softened
1/2 cup brown sugar
1/2 cup white sugar
1 egg
3/4 cup peanut butter
1 1/4 cup flour
1/2 tsp baking soda
1/2 tsp vanilla

Mix butter, sugars, and peanut butter together. Add eggs, flour, baking soda, and vanilla extract and mix well. Drop by tablespoonfuls onto cookie sheet.

Bake at 350 degrees for about 12 minutes or until golden brown. Makes about 30 cookies.

I found the recipe here on cooks.com.
