Remove the frozen bananas from the freezer and allow to stand for about 10 minutes. It makes it easier on the high speed blender as solidly frozen bananas are quite hard.
Add all the ingredients to a high speed blender and process on high for about 5-7 minutes until well mixed and smooth.
This ice cream is creamiest when enjoyed immediately. You can store in the freezer, but because it isn’t made in an ice cream maker, it will be a bit icier than the alternative. Still.Very.Good!
