This is by far the easiest, healthiest and most delicious banana ice-cream I have ever eaten. All you need is banana; no sugar or milk needed. When banana go on sale in the store, it is usually really ripe and it is about to spoil soon. Buy the banana, chop them up and throw it in the freezer. It could last you for at least 2 weeks. When you are ready for some banana ice-cream, take them out and grind it in the mixer. The trick is to let it cool down for it so that it is easier to grind. I put some Oreo and Pecan nuts topping. Totally down to try to chili flakes or dark chocolate the next time!
