To the smoothly mashed bananas, add the milk, cream, sugar and vanilla. Beat well until homogeneous and optionally put in a little yellow confectionery dye for it to acquire a more appetizing appearance.
If you have a machine for ice cream, put the mixture in it for 30 minutes. If you do not, put the box with the mixture in the freezer and after about 30-40 minutes, remove and stir it again.
Put it back in the freezer until it begins to freeze. Then remove it and stir it well one last time. All you have to do now is leave the homemade banana ice cream to freeze for several hours.
