1/2 c. peanut butter
1/2 c. butter
1/2 c. white sugar
1/2 c. brown sugar
1 egg
1 1/4 c. plain flour
1/2 tsp. salt
1/2 tsp. baking soda
1/2 tsp. vanilla

Set oven to 350 degrees. Beat peanut butter and butter together. Add sugars. Sift together flour, salt and soda and add to mixture. Then add the rest of the ingredients. The mixture will be stiff enough to hold its shape. If too soft, add a little flour. Grease 2 cookie sheets.

Arrange teaspoonfuls of the mixture on the cookie sheets, leaving 2 inches between them. Press flat with a floured spoon. Dip a fork in flour and press each cookie to make a pattern. Bake about 10 minutes. Set aside to cool.
