68 cals - so 3.5syns at a rough guess though the calorie information is conflicting (unlikely to be any free food allowance in that!) and these are the ingredients (I'm not veggie, so not sure what to look for!)
Skimmed milk (65%), water, sugar, chocolate (3%)(sugar, cocoa butter, skimmed milk powder, cocoa mass, lactose, vegetable fat, whey powder, milk fat, Emulsifiers: Soya lecithin, E476, water, flavouring), cocoa powder, stabilisers: modified tapioca starch, E460, E466, E415, E407, whey powder, malt extract, glucose syrup, skimmed milk powder, emulsifier: E471, wheat flour. (Heat treated)
