To make Eggless Tiramisu, Combine mascarpone cheese and whipping cream/ double cream together in a large bowl. Beat this mixture using a handheld beater until a soft peak is formed. Add icing sugar and vanilla extract and beat again. Set this aside.
Dip the ladyfingers in the coffee until they are equally soaked on both sides.
If you are using just one dish, divide the ladyfingers in equal numbers and spread one-half of the coffee dipped ladyfingers in the dish, and spread half of the cream on top of this layer.Pour the chocolate syrup on top of this. Repeat the layers and finish it with cream on top. Dust the cocoa powder on top and refrigerate it for 1 hour before serving.
