Carvel ice cream cakes are made fresh every day. We use the highest quality ice cream, but the quality is also dependent on the design of your home freezer. Over time, ice crystals form in ice cream which diminish the smooth texture and rich flavors. While ice crystals are not harmful, we recommend you enjoy your Carvel ice cream cake within 7 days of purchase to ensure you get that you get "Holy cow, that’s tasty" experience.
