To easily cut fudge, remove it from the pan by pulling it up with the parchment paper. Slowly peel the paper off of the fudge and transfer it to a serving plate. Wait a few minutes for it to come to room temperature, then use a knife to cut it into squares. If the knife doesn't slide easily into the chilled fudge, rinse the knife with hot water. Then dry it and use the warm knife to cut through the cool fudge.
