Place peanut butter and softened butter in a large bowl, and beat with an electric mixer on medium speed until well blended.
Gradually add powdered sugar and mix on low speed until combined.
Shape into 1½-inch balls, and place on a baking sheet lined with parchment paper.
Place chocolate chips and shortening in a glass bowl, and microwave on HIGH power for 1½ minutes, stirring an each 30-second interval.
Dip about ½ inch of a lollipop stick into the melted chocolate, and then insert about three-quarters of the way into a peanut butter ball. Repeat with remaining balls.
Place in the freezer for about 20 minutes, or until firm.
Stir melted chocolate, and if necessary, microwave minimally to re-melt. Hold a peanut butter ball over the bowl of chocolate, and use a spoon to drizzle with melted chocolate, rotating the ball to coat all sides evenly.
Allow excess chocolate to drip off before placing the ball back onto the parchment-lined baking sheet. Repeat with remaining balls.
Store coated balls in the refrigerator or freezer until ready to serve.
*Note: Extras can be frozen for up to 3 months. Allow to thaw at room temperature, or enjoy frozen.
