Flourless Peanut Butter Cookies

These are the best peanut butter cookies EVER! Aunt Karen gave me this recipe years ago, and I've been famous for them ever since.

1 cup peanut butter (creamy or crunchy will work)
1 cup sugar
1 egg
1 tsp vanilla

Preheat oven to 350. Put egg in the bowl and whisk with a fork until frothy. Add sugar and mix well. Add vanilla and peanut butter. Make sure its thoroughly mixed!

Make small balls (big ones don't work as well) on a cookie sheet, then flatten slightly with a fork. Bake 10-12 minutes.
