Chocolate & Prune Refrigerator Bars

Made these for a friend for her birthday (she loves prunes) and I guess they didn't last long...easy and quick. From Best Ever Three & Four Ingredient Cookbook. They came out rather thin; adding more chocolate wouldn't hurt, I think. Also I recommend lining the pan with parchment paper or spraying with cooking spray so that the bars are easier to remove. Cooking time is chilling time. I don't know why, but recipezaar insists that the ingredient be listed as "prune", not "prunes."
