Beat together the peanut butter, sugar, vanilla, and egg.
Stir in the chocolate chips and then scoop onto a cookie sheet.
Press a few extra chocolate chips into the tops of the cookies if desired.
Bake for about 6-8 minutes or until lightly browned around the edges. Remove from the oven and allow the cookies to sit on the cookie sheet for another 2-3 minutes before removing to a cooling rack.
