In a bowl, mix together the powdered sugar, butter, cracker crumbs, and peanut butter until smooth. Give it a taste and add some salt if needed. Chill the mixture for 20-30 minutes until it is firm enough to form into balls.

Line a baking sheet with parchment paper and start forming teaspoonfuls of the mixture into balls and placing them on the sheet. When done, chill for another 20-30 minutes.

Melt the chocolate in a metal bowl set over a pan of simmering water. Dip the peanut butter balls one at a time letting the excess to drip off and put them back on a baking sheet.

Cover and chill until ready to serve. Enjoy!
