Cream the butter and peanut butter.

Add the vanilla.

Add the powdered sugar a little at a time, incorporating it until it is thoroughly mixed and the mixture is fluffy.

Pinch off a little dough and roll it into 1" balls (or smaller, if you prefer).

Melt the chocolate chips in the microwave. The time varies, depending on your microwave. Start with 30 seconds. Stir. Repeat until the chocolate is melted. Be careful, as chocolate burns easily in the microwave and you cannot see that it is melted or burning until too late!

Drop the balls a few at a time into the chocolate mixture. Dip them out with a teaspoon, trying not to get extra chocolate dripping around them. (Or stick a toothpick into the ball and dip the ball into the chocolate.)

Cool the balls on a sheet of wax paper.

Or, you can use mini cupcake papers instead of the dipping method. Pour some chocolate into the cupcake paper. Drop in a ball of dough and pour some more chocolate over the top, similar to the way Reese's Peanut Butter Cups look. (This way is MUCH easier.)

If using, melt the paraffin either in a double boiler over boiling water or in a bowl in the microwave. For the microwave, it takes about 3-4 minutes, but watch it and take it out as soon as it is melted.

Add the chocolate chips to the paraffin and melt them, watching the mixture carefully and stirring to combine.

Let the candies cool until set.
