transferring from a round tin to a bundt, timings?

[Playduh]

Help!

I'd i want to change a cake recipe from a 20cm standard cake tin, to a 26cm bundt tin, do I need to alter the baking time or not?

If so, how do I do it? Current cake baking time is 35 mins at 160deg.

TIA

I'd keep an eye on it and check after 25.

Thankyou!

I've only opened this to find out what a bundt is ?

???

It's a round ring tin, usually with a fluted outside (like a jelly mould)

Thank you.
