I tried the banana ice cream a few years ago and it's amazing, I freeze the banana with some tinned pineapple drained, or berries, then I mix in a little orange juice or fresh lime juice, also done it with diet lemonade, you don't have to use ripe bananas as they have more sugar, sometimes I mix the ingredients before I freeze then add the juice after.
Oh my god, I can't wait to try this! I found something similar on Pinterest but without all the flavourings. So looking forward to this evening now - I even have enough points left to top it with golden syrup and nutella. YUM!
