How to make
Mix well the mascarpone, sour cream, and powdered sugar.
Melt the chocolate over a water bath or in the microwave. Cut the banana into thin circles.
Warm the milk slightly. Dip the biscuits into the milk and arrange them in a tray.
Arrange the first row of biscuits, pour the cream, and level it. Arrange banana rings on top. Drizzle with a little of the melted chocolate. Repeat with the second layer of biscuits and so on until the products are finished.
Finish with cream, garnishing with melted chocolate. Place the biscuit cake in the refrigerator for an hour to cool.
