Adjust the bake time too
A bigger tin spreads the batter thinner, so it bakes faster. Start checking at 80% of the original time.
This compares by area, so it is right when the tins are a similar depth. If the depths differ a lot the batter thickness changes and the bake time shifts considerably. Fill a tin only 60–70% of the way.
