But if you're on the lookout for an incredible store-bought ice cream cake, keep in mind that not all of them are created equal. Granted, every ice cream cake is a little bit different — some have layers with actual cake, while others might be mainly ice cream with a filling or topping made of cookie crumbs or "crunchies". The point is that there needs to be some balance between the creamy, silky ice cream and the other components. I've taste-tested seven different ice cream cakes and determined which are worth buying and which aren't. Of course, the overall quality of the ice cream is crucial since it is the primary ingredient.
