You will need a large glass 14-ounce trifle bowl or a large glass dessert bowl for this. Purchase the regular size candy bars for this, you can really just use as many bars as you wish. I just purchased the small pudding cups and used them as I could not find a large tub of ready made chocolate pudding. This is a perfect dessert to serve for a dinner party as it can be prepared 24 hours in advance. Plan ahead this needs to chill for a minimum of 2 hours or up to 24 hours before serving. Chilling time is cooking time.
