Quick cake question for novice

[Eminybob]

I'm baking cake for my son's birthday tomorrow. It'll be a classic Victoria sandwich but covered with buttercream.
I want to bake it tonight and ice it tomorrow as I'm working in the morning so won't have time to do both with cooking time in between.

Anyway my stupid question is, how should I store the 2 cakes between them cooling tonight and when I ice them tomorrow afternoon? Fridge? Out uncovered? Or out covered. And if covered, covered with what?

Thank you!

*cooling time in between

Pop them in a large tupperware or airtight cake tin with greasproof between the layers to stop them sticking and they can be left out. Make sure they're completely cool before you pop them in though. Or wrap each one in cling film and leave out. Again make sure they're cool first. Hope your ds has a lovely birthday!

You are brilliant, thank you!

Don't forget to get the butter out the fridge in the am so its room temp to make the icing. Its much easier to butter ice the cakes when they're slightly firm straight from the fridge so leave them in the fridge until last minute.

Thank you!
Ah well I drew the line at making the icing, I've bought ready made . Next time I will but this is big step for me, all his previous cakes have been supermarket ones!
But thanks for the tip
