Put the crème fraîche, milk and sugar in a tall container. Tear the banana into pieces and add them. Puree with the blender for approx. 2 minutes and beat.
Spread on dessert bowls or small cups, dust with cinnamon or cocoa powder if necessary and serve immediately.
Tip: It is best when the crème fraîche and the milk are very cold.
Variants: vary with different types of fruit. But watch out for the amount of milk so that the cream does not become too runny. Or scrape out the pulp of half a vanilla pod and add it to the cream. Some of the sugar can also be replaced with vanilla sugar.
