Preheat oven to 350 degrees. In a large bowl, combine peanut butter through vanilla until mixture is smooth. Fold in chocolate chips.
Line a cookie sheet with parchment paper. Scoop a tablespoon of dough out and roll between your hands to form a ball. Place the balls of cookie dough an inch or two apart on the cookie sheet. Flatten the dough with a fork in a crosshatch pattern.
Bake 10 minutes, turning the pan front to back halfway through cooking time. The cookies should be lightly golden. Watch carefully, do not over bake. Cool the cookies on the pan. Once cooled, they should lift easily off the parchment paper.
