Banana custard without sugar

Put almost all the milk in a saucepan with the cinnamon and heat over medium high heat.

Meanwhile, in a blender glass, put the rest of the ingredients and blend well.

Once the milk has started to boil, remove the cinnamon, lower the heat and pour the mixture from the mixer into the saucepan with the milk and stir with a whisk until it has the desired thickness.

Serve in individual containers and let them cool at least overnight. It can be decorated with a little grated coconut or cinnamon at the moment it is going to be eaten.
