Remove the top/dome shape from the cakes, so we have 2 flat level cakes. Use a sharp serrated knife
Put a spoonful of whipped cream on the plate that you will use to assemble the cake(this acts like glue to keep cake in place)
Put your first layer of cake. Put 5-6 tsp of sugar syrup on 1st cake layer. I used a spoon to drizzle it over the cake. Both cake and sugar syrup are at room temperature
While the kaju katli layer is still WARM, flatten the dough with your hands and place it over the 1st cake layer. You may have to break the dough and fill in to get a 1/2 inch thick layer of kaju katli dough. The dough may not be perfectly smooth, but as long as its even and flat and completely covers the cake, its ok.
Add a spoonful of whipped cream and spread it over the kaju katli layer to act as glue to hole the second layer of cake in place
Put sugar syrup on second layer and place it carefully on the kaju katli layer
Do a crumb coat-Put a very thin layer of whipped cream icing on top and sides of the cake. Use offset spatula or spoon to put the whipped cream. Crumb coat is a very thin layer of icing applied first to cakes to get a smooth finish. Put in the refrigerator for 15 minutes for the crumb coat to set. Put the remaining whipped cream in the refrigerator also.
After 15 minutes put a generous layer of whipped cream icing on top and sides of the cake. Use an offset spatula to level the top. Use back of spoon to get vertical lines on the side of the cake.
Put the kaju katli with the pointed edges facing inwards. Fill the center with chopped pistachios and rose petals. Stick some rose petals and pistachios on the sides of the cake. Pipe some flowers at the edge of the cake. Put in refrigerator to set.
Take out from fridge 20 minutes before to cut as the kaju katli layer that has butter has a chance to soften a bit before serving
Store in refrigerator
