In a medium bowl, combine peanut butter, sugar, egg, and vanilla extract, if using until well blended.
Using a teaspoon or small ice cream scoop, drop dough two inches apart on a ungreased baking sheet.
Using tines of a fork dipped in sugar, press on top of each dough in a criss-cross pattern.
Bake in a 350 F oven for about 10 minutes or until lightly browned.
Remove from oven and allow to slightly cool. Transfer to a rack to cool completely.

Use a small ice cream scoop to portion out the dough for uniform sizes. Roll in the palm of your hands into balls to make the baked edges smooth and even.
If the dough is too soft to hold shape, refrigerate for a few minutes to chill and firm up.
Press down on the dough using the tines of a fork to flatten and add a criss-cross design.
