The World'S Best Peanut Butter Cookies

Directions

1. 1
   ["Preheat oven to 375 degrees.", "Cream together butter, peanut butter, brown sugar and sugar until nice and smooth.", "Add egg and vanilla and beat in well with a spoon.", "Gradually add the self-rising flour. Dough will be stiff.", "Form one inch balls and roll in sugar (I like to toss a dozen of the dough balls into a bag with sugar, shake gently to coat and then leave them in the bag for a couple minutes so a thicker coat of sugar adheres to the dough, then give another light shake before removing them from the bag. But just giving them a quick roll is fine).", "Place sugared dough balls onto an UNGREASED baking sheet about 2 inches apart. Flatten balls with the back of a fork (or if you want flat tops you can flatten them with the bottom of a drinking glass. I usually flatten them with the textured side of my meat cleaver giving the cookies a nice waffle pattern).", "Optional step: You can sprinkle a little extra sugar onto the tops after they are flattened if you like. It adds a little \"crunch\"" to this soft cookie.""
