Gradually add powdered sugar until well combined. You may need to dump onto a piece of wax paper and knead until all combined (especially if peanut butter is on the dryer side. Jif and Planter's are moister and work well).
Pinch off little pieces of the dough and roll into balls. Place rolled balls on a wax lined cookie sheet. Once cookie sheet is full place in freezer. Continue rolling balls until all the dough is gone. Then place that cookie sheet in freezer.
In a double boiler melt chocolate and paraffin wax until completely melted.
Take out first cookie sheet only. Stick a toothpick or a skewer in a ball and dip into the chocolate mixture, rolling it to make sure they are completely covered. Place back on tray. Repeat. (I use several toothpick to let the chocolate harden)
*If you start to run out of chocolate I take small chunks of wax and a handful of chocolate and remelt it. Repeat if needed.
