Firstly deep freeze the sliced bananas for over night or 6 to 8 hours.

Then to a blender add the deep freezed banana slices, sugar and vanila essense, if u r on diet you can skip the sugar and them blend all the above ingredients without water, then a thick creamy paste is formed then transfer it in to silicon moulds and deep freeze it for 2 -3 hours.

Now in to the serving plate transfer the banana ice cream from the moulds enjoy it.
