Cottonball use the fantasy fudge recipe on marshmallow fluff jar, instead of chocolate chips use peanut butter chips and a scoop of chunky peanut butter its easy peasy !!!!!!
I always had trouble with fudge, had a lot of chocolate hot fudge though.
A friend of mine in Utah told me this works every time and it sure does.
So easy.....
Three minute fudge.........I skip the nuts.
Oh and use a wooden spoon to beat it, recipe says rubber spatula but she told me to use a wooden spoon.
