How to make
Make a dough from the ingredients for the cupcakes. Divide it up into balls, stretch them out along the bottom and sides of your cupcakes.
Bake them 10-15 min. in the oven, then take out right away. In the meantime, prepare the cream by mixing together 1/2 the milk and the condensed milk .
Boil them on low heat, then in a thin trickle pour in the beaten together flour, sugar, rum, egg yolks and set aside milk.
Stir energetically and add the butter. Once the cream thickens, remove from the heat. Fill the cupcakes with it. If you have a pastry bag, use it.
