(adapted from Paula's recipe on FoodNetwork.com)
2 c peanut butter
3 c granulated sugar
2 tsp vanilla extract
Reserve 1/3 c of sugar and mix the remaining ingredients together. You can add chopped peanuts or use chunky peanut butter if you prefer the texture. I didn't. Using a miniature ice cream scoop I dipped in sugar, I formed 1½" cookie balls and then flattened with a fork, also dipped in sugar.
Bake at 350 for 10-12 minutes. Before they cool, sprinkle the tops with sugar, then let sit on the cookie sheet for a couple minutes before transferring to a cooling rack.
