This is the best and easiest peanut balls recipe I've tried, plus for me, it's a nofail recipe. A few notes: Chocolate Peanut Butter Balls with Rice Crispies. If you like more texture and crunch, you can add in 3 cups of crushed rice cereal. Just measure out 3 cups and give them a little crush. Don't pulverize them, just break them up a little.
