This is superb for a party or brunch. It is different and satisfying – not quite chocolate soufflé cake and not a cheesecake but somewhere in-between. It is as good served chilled in wedges with warm white chocolate sauce as it is slightly warm out of the oven, with caramel sauce or whipped cream or even a scoop of softened vanilla ice-cream. Use leftover chocolate cake such as Classic Dark Chocolate Layer Cake and leftover Notting Hill Brownies (without any nuts in it) or your own. If you are really time-pressed, use leftover store-bought or a mix. I give you permission for the final results of this cake are more than the sum of the parts (although homemade everything makes it cake Utopia). And if you don’t have enough cake - use more brownies; or vice versa or make up the difference with the bread chunks. It is a flexible recipe. Chocolate extract is optional but a nice touch. Nielsen Massey makes it and can advise you where to find it online or in stores.
