Chocolate Coated Peanut Butter Candies

Folks-
This is a variation of an old recipe I found in a Betty Crocker's Cookbook. I first tried the recipe when someone else gave me one of these, and I loved them! This is really using their changes from the original recipe. Unfortunately, I don't remember just who it was, except to say that they worked with my mom at Live Oak Elementary School.
Here's the recipe:

Ingredients:
1 1/4 Cups Creamy Peanut Butter
1/2 Cup Margarine or Butter, Softened
4 Cups Honey Graham Cereal, Crushed into Coarse Crumbs (a food processor works well for this)
2 Cups Powdered Sugar
1 Tablespoon Shortening
1 Cup Chocolate Chips

Mix peanut butter and butter or margarine in a large bowl; stir in cereal crumbs. Mix in powdered sugar, 1/3 at a time. Press mixture into a melon baller and drop onto an aluminum foil lined cookie sheet, or similar surface. Mix the chocolate chips and shortening in a small bowl and melt in a microwave, stirring the mixture every 20 seconds or so. Dip the candy balls one at a time into the melted chocolate, fishing them out with a fork and replacing them on the aluminum foil lined sheet. Refrigerate for about 10 minutes or until the coating is hardened.
