This Thermomix recipe takes the classic chocolate and raspberry combination to the next level by adding a creamy mascarpone filling. The sponge is made with dark chocolate and cocoa powder, giving it a rich and intense flavour. The truffle filling is made with dark chocolate and cream, and is infused with raspberry puree for a fruity twist. The mascarpone cream is made by whipping together mascarpone cheese, cream, and sugar, resulting in a light and fluffy texture. The cake is then topped with fresh raspberries and a dusting of cocoa powder. This cake is perfect for special occasions or as a luxurious treat for yourself.
