Ice Cream, but Cake is also among my favorite desserts. Chocolate or Cheese Cake = Heaven. For Ice Cream I prefer vanilla with lots of toppings or in a Sundae.
Proper Walls ice cream, the stuff that's bright yellow, contains no milk fat, is probably made out of the bits of pig they couldn't even squeeze into economy sausages and which is Vanilla style flavour.
I enjoy both...
I agree with gunslingingbird, if you want both, have ice cream cake.
Ice cream cake is the usual for my family for birthdays,
instead of the traditional birthday cake.
