World's Largest Ice Cream Cake -- and it's a Carvel cake, baby! Sure, there's better ice cream out there, and sure, nobody knows what that exactly is in that crunchy, delicious, chocolate gravel layer betwixt the vanilla and choc ice cream layers, and yes, we'll probably get brain cancer from eating all that fluorescent blue gel icing -- but so what? Nothing beats nostalgia, and in my family we had Carvel cakes on our birthdays, mmmmmm. Good god, will you look at this?! All together now: *droooool.*
