This is a chocolatey peanut butter cookie with a hint of banana. I like to use flavored peanut butter to give it some flare. I have used chocolate-peanut butter. You can also use a cinnamon raisin peanut butter or a white chocoalate-macademia PB. They are made by Peanut Butter & Company, and it can be found in the PB aisle at most grocery stores. Usually on the top shelf.
