Preparation:
Mix together the peanut butter, sugar and egg. Scoop out a spoonful of dough and roll it into a ball. Place onto a nonstick baking sheet. To make them cook more evenly, flatten the cookie balls by pressing a fork down on top of them, then press it down again at a 90 degree angle to make a crisscross pattern. Bake at 350 degrees for 8 to 10 minutes or until the bottoms of the cookies are golden brown. Remove from baking sheet and cool.
