So what you're saying, Errol, is that you prefer a cake to be less cake and more convenient mechanism for delivery of dairy products,
Ah, one of those 'what you're saying' calumnies ... crumble, not cake, and you obviously need more of it if it's got to accommodate multiple toppings.
Fantasy, I'm afraid; the unfortunate reality in my house would be that we never have cream in, DH would have eaten all the custard, the ice cream wouldn't be the right sort of flavour to go on a fruit crumble and so I'd have to settle for a dollop of Greek yogurt.
