Carrie's Peanut Butter Cookies

I have made peanut butter cookies every which way and I could never find one that had JUST the right amount of peanut butter, but ALSO had the texture to stay together after cooking. I loved the flavor of the ONE of everything recipe, so I worked with that to make my own recipe and wanted to share.

1 cup of Peanut butter (I just use Kroger)
1 cup of sugar (either brown or white, I use 1/2 cup of each)
1 teaspoon vanilla
1 egg
2 level tablespoons of flour.

Mix all together. Roll into balls and flatten with fork making the criss cross shape on a cookie sheet. Bake for 9-11 minutes in a 350 degree oven, depending on how "done" you want them.
