PB Balls...I must have for the Holidays!

2 cups of powdered sugar
1 cup of PB
6 tbsp of butter
almond bark (chocolate).
Mix the 3 ingredients together & then roll into balls, place on wax paper. Melt the almond bark on the stove top on LOW until melted. I always dip the balls with an ice cream scooper, it seems to coat them really well. Let dry & serve! YUMMM-O!
