Does anyone have a clue as to how long it takes to cook a normal sized banana cake (not a packet mix one but roughly the same size) in one of those bench top convection ovens?

Hi Ma,
I was just looking through the recipes and saw your question about cooking time.
I have a bench top oven "They call it a Turbo oven" i do all sorts of cooking in it when i do a cake such as banana it takes about 40-45minutes at about 180oC all ovens vary test it at about 40min.
Hope this answer is not to late and will help you out.
Have a great day happy cooking........

They say life is short and the road ahead is long.
So don't spend too much time looking in the rear vision mirror.

Hi Ma, I have a friend who has one, and she says that cakes generally cook more evenly if you use a Ring Tin. Have e-mailed you a couple of her recipes, as I have no idea how to put them on here. Cheers, xina.

The ring tins do work better apparently, but I haven't yet found a suitable one.

I have an aluminium pudding steamer which, when used without the lid, seems to work reasonable well even if it does produce the wrong shape for a cake

Thanks Xina, Kay and Rolly.  Will let you know how it turns out and then you can all come for morning tea if it's success
