This one is not one of my recipes I found it on allrecepies.com and it was perfect just the way it was. It's originally by Angieh and it's called Easiest Peanut Butter Fudge. Instead of using brown sugar we use panela in ours. Panela is slightly healthier then brown sugar (i.e. not processed as much) and it comes out tasting divine.
