This has got to be the easiest recipe yet for this wonderful cookie. Don't be put off by the simplicity of it...and despite challenges to the contrary, the recipe works WITHOUT flour.
1 cup sugar (you can cut this down to 3/4 cup, if you prefer)
1 large egg
1 cup peanut butter (crunchy or smooth)
Combine sugar and egg in mixing bowl, stirring till smooth. Add peanut butter and mix in thoroughly.
Roll into walnut-sized balls.
Place the balls on ungreased cookie sheets at least 2" apart.
Flatten with the tines of a fork.
Turn 90 degrees and use fork again to create cross hatches.
Bake 10 minutes at 375F (or till done). Let cool in pan for 1 minute before removing to cooling rack.
