Pour into your ice cream molds. Transfer to the freezer for at least 5 hours or overnight.
Release the magnums and dip each of them into the peanut butter. If you have a very thick peanut butter, microwave the jar for 30 seconds or warm up in a water bath until liquid.
After dipping your magnums in peanut butter return them to the freezer for an hour before placing them on a sheet of baking paper.
Melt your chocolate and dip the magnums into the chocolate. Return to the freezer for 10 minutes and then enjoy your Vegan Peanut Butter Magnums one at a time!
