Put the strawberries, milk, cream, and bananas in the blender and blend until obtaining a homogeneous and consistent mixture. If it is too liquid, add more strawberries and banana.
Pour the smoothie in a large bowl and refrigerate.
Slice the berries thinly so that the mixture can hold them in the surface.
Take the cold smoothie out of the fridge and decorate forming a mandala and adding nuts to taste.
