For the dough, whisk butter, brown sugar, marzipan paste, cottage cheese and the pulp of the vanilla bean until fluffy and add a pinch of salt. Gradually stir 2 whole eggs and the yolks of 4 eggs into the butter mixture until it is nice and smooth.
Beat the whites of 4 eggs with powdered sugar until creamy (not too firm) and then fold into the egg-butter mixture.
Mix flour and ground hazelnuts in a bowl and gently fold into egg-butter mixture. Mix the grated zest from the oranges with the curry powder and Baileys Hazelnut Flavour and stir into the mixture.
Place the 12 cupcake baking cups in the wells of a cupcake tray. Pour in the batter. Bake in a preheated oven at 190 °C (gas: level 3-4 / convection oven: 170 °C) for approx. 25-30 minutes.
For the chocolate Baileys ganache, melt the dark chocolate coating in the microwave or in a water bath. Once completely melted, remove from heat and stir with Baileys Hazelnut Flavour until smooth and ready to pipe.
Place the topping in a piping bag and pipe on top of each other in individual layers using a flat piping nozzle (the cupcakes must be completely cooled). Finally, decorate the cupcake with an orange spiral.
