Line a baking sheet with parchment paper.

In a medium bowl combine peanut butter, softened butter and vanilla. Stir until well combined. Add powdered sugar and brown sugar and stir until combined. You may need to use your hands.

Add crushed pretzels and use your hands to incorporate in the dough.

Roll 1 inch balls and arrange on prepared baking sheet. Refrigerate for several hours or overnight.

Melt the chocolate chips and chocolate coating in a small, deep bowl by microwaving at 30 second intervals, stirring until smooth. Dip each ball in the melted chocolate, shake off excess and arrange on prepared baking sheet. Garnish with sprinkles if you like. Refrigerate until the chocolate has set.

The candies taste especially good if you let them come to room temperature before eating. Store in an airtight container in the refrigerator for up to 10 days.
