My interpretation of a Barbie⦠Chocolate with home-made raspberry syrup and dark chocolate ganache for all tiers but the bottom - roasted hazelnut ganache with Kahlua. All are 2â, torted in 3 layers, for a finished height of 3â; 12-10-8-6-4-inch rounds for a party of 35-40 people - only the secret spiked bottom tier remained 5 minutes after slicing the cake â everything else was devoured!!! Used 4lb of dark chocolate⦠The smash cake is scratch organic vanilla sponge with Mascarpone filling and frosting.
