Procedure

With a whisk, work the butter with the sugar, then add the egg. Add in 2 moments flour and then yeast. Towards the end, mix the mixture with your hands. Be careful not to knead it too much and not to overheat the butter in the dough. Let the pastry rest in the fridge, covered with a transparent film for at least 1 hour. Combine the pureed banana with all the cupcake ingredients and mix with the electric whisk until a homogeneous mixture is obtained. Put it into cupcake stencils and put them into the oven at 170 degrees for about 40 minutes. Durante la cottura dei cupcake, a parte, prepara il frosting: in una ciotola monta il burro con una frusta insieme allo zucchero a velo, aggiungi poi il formaggio spalmabile precedentemente lavorato e reso liscio. Bring the cream to the boil in a saucepan and add the chocolate, melt and work until you get a smooth and shiny cream. With a licker, combine the two compounds and pour everything into a sac à poche. Before decorating the cupcakes, let both the muffins and the frosting cool.

Suggestions: You can make the dessert even more delicious by adding a few flakes of dark chocolate or the seeds of a vanilla pod to the cupcake mixture.
