Stale banana cake -any recipe suggestions?

[aubergenie]

I've got half a stale banana and walnut cake that isn't going to get eaten as it is. What can I do with it? Do you think a bread and butter pudding type thing would work? Or I was thinking of somehow transforming it into a crumble topping. Any suggestions?

trifle base?

start of a banoffe pie?

I'd go with the bread and butter pudding thing. The custard layer will moisten it.

bubble and squeak surprise?

Thanks for the suggestions - I've made the bread and butter pudding thing - it's just come out of the oven and looks pretty good!

I've got a cold and am really in the mood for comfort food. Yum.
