My fave has always been plain old smooth vanilla - simple & classic (or boring?)
i freeze mine they are lovely and they last so long. try them for yourselves i bet you'll prefer them this way.
Banana & Custard Vanilla flavour with a sliced banana, lovely....
I've got to go for the Cherry one out of the chocolate sprinkles multipacks. It's syned but worth it. Layer of Cherry and Chocolate sprinkles... amazing!!
Shame they don't sell them individually.
