Raspberry & cranberry, although I have to be strict with myself and force myself to have others for variety! The limited edition berries one is yummy too.
Rhubard Crumble flavour - thought I think it's only available sometimes.
April and Mandarin
Don't like the toffee flavour much, but if you crush a tiny snack size pack of maltesers into it and then freeze it makes lovely low cal/low fat ice cream
