What is the difference between lactose and maltodextrin? Which is better to use for a creamy beer? Can I use both? Is it better to add them during the boil as well as at bottling, or just at bottling?
I add lactose to a cream stout, it makes it sweeter (its a less-fermentable sugar) and adds body, which is probably what you mean by creamier. I add the lactose to the boil with ten minutes or so to go, but either method is acceptable.
