Looking for a quick and easy dessert recipe that takes just 15 minutes to make? You'll love this Easy Eclair Icebox Cake recipe. An old-fashioned no bake icebox cake with layers of graham crackers, pudding, and chocolate icing. It's a cool and creamy layered dessert made lighter, perfect for hot days. A big hit with friends and family, I've lightened it up with sugar-free pudding, low fat milk, light cool whip and fewer graham crackers. For best results this eclair cake needs to be kept refrigerated until you're ready to serve it and then promptly returned to the refrigerator to ensure that it doesn't soften up too much.
