How to make
Pour the vanilla into the milk and boil it. Meanwhile, beat the yolks with the sugar until they foam up and carefully add the flour. Remove the milk from the heat and allow it to cool slightly.
Carefully pour the milk into the egg mixture, while stirring constantly. Place it back onto the hob, bring it to a boil and boil it for 4-5 minutes until it thickens, while stirring the cream constantly. Add the butter and remove it from the heat.
Cut the bananas into circles and arrange them on the bottom of the serving cups. Pour the egg custard on top and allow it to cool before serving.
