Next prepare the surface to roll out the candy. Cover the surface with wax paper and spread a thick layer of powdered sugar.
Next mix all ingredients except vanilla, egg whites, and peanut butter in a large pot and boil. Stirring continuously, until ball forms. (Like when making fudge or candies) the ball should be hard and have a soft crack. Add vanilla.
Slowly pour the mixture over the egg whites while mixing with a blender the whole time. Continue to mix until the candy has cooled and resembles the texture of marshmallow cream.
