For the base: 350 g of dry cocoa biscuits, 110 g of melted butter. For the filling: 250 g of already sweetened whipping cream, 250 g of mascarpone, 70 g of icing sugar, 30 g of instant coffee
To create our grandfather's cup cake, let's start by crumbling the biscuits or passing them in the food processor. In a bowl we then put the chopped biscuits and melted butter, mix and pour three quarters of the mixture into the mold that we will use and level it through the back of a spoon. Let it rest in the fridge for 30 minutes. Prepare the filling by placing the cream and the icing sugar in a bowl, turn on the electric whisk and add the instant coffee and mascarpone as we whisk. Once everything is well mixed, sprinkle our cream over the entire base and level well. We cover the surface with the remaining chopped biscuits we had kept aside. Let it rest in the fridge for 4 hours or better still overnight. After the necessary time, we put our cake on the platter, sprinkle with bitter cocoa and enjoy!
