Line 2 baking sheet with parchment and set aside.

Combine the confectioner's sugar, peanut butter, softened butter, vanilla and salt in a large mixing bowl with an electric mixer. Start on lowest speed then increase as ingredients are combined. The mixture will be crumbly.

Use a 1 inch scoop to portion out filling then use your hands to shape into 1 inch balls and place on lined baking sheet. Cover and chill the peanut butter balls in the refrigerator for at least 1 hour or overnight.

Melt the chocolate and shortening in the microwave on high for 45 seconds to 1 minute, stir until smooth. If needed, microwave in additional 15 second intervals until melted and smooth.

Use a fork to dip the peanut butter balls in chocolate and roll around until coated then transfer the chocolate peanut butter ball on a lined sheet pan. Reheat the chocolate if needed while coating to keep smooth and melted consistency ( I re-heated a few seconds about halfway through coating)

Chill until firm.
