D.S.
I haven't read the others, but my recipe is:
1 cup peanut butter
1 cup sugar
1 tsp vanilla
1 egg
Place all in a bowl, mix by hand until dough starts to pull away from the sides (2-3 minutes), scoop onto cookie sheet (i use a tablespoon to scoop), press with fork and bake for about 13 minutes at 350 degrees. When you take them out, pop a kiss in the middle. Takes me around 18 minutes total to make them!
