Cream together butter and peanut butter until well blended and smooth, adding the sugar gradually to mixture. Beat until mixture is light and fluffy.

Add 1 egg, well beaten; stir in vanilla. When well mixed, add flour mixture, stirring until mixed. To avoid tough cookies, do not beat - stir only until mixed.

Drop by the teaspoonful onto a greased or parchment-lined baking sheet and press a criss-cross pattern onto the top using the tines of a fork that has been dipped into flour.

Bake in a preheated 350°F oven for 8 minutes. Do not overbake.

Makes about 3 dozen.
