A traditional ice cream cake has cake layered between the ice cream layers and is toped with your favorite type of icing like cream cheese icing. However, there are some ice cream cakes that are made completely of ice cream in the shape of a cake. Honestly, I love them both.  This cookies and cream ice cream cake does not have caked layered in and is made mostly of ice cream.  I love making this for a summer holiday or to celebrate a summer birthday as I can whip it up in no time at all!
