Hello! I only bake cakes for family parties and so I am not as seasoned as you pros out there. Here is my question.

My sister's birthday party is on Sunday (today is Friday). Yesterday I baked the cakes and let them sit overnight. Today I was going to fill the layers and crumb coat it. I have read a lot about making the dam for the filling but here is my question...

If I do all of that this afternoon, should I put it in the fridge overnight until I cover it tomorrow? I have read that I should let it sit for a while to see if the layers bulge a bit, and then to correct it before covering it, but if I don't plan on covering it until tomorrow should I refrigerate it or leave it out on the counter? If I refrigerate it, won't it just harden up and I wouldn't know if it was sturdy or not? But if I don't put it in the fridge, isn't it a bad idea to leave out a buttercream frosting and a chocolate truffle filling for that many days? I was planning on refrigerating it but now I am having second thoughts.

Anyways, that was my plan. Let me know if I should be doing something else! Thank you thank you!

WHat I do is.. fill and crumb coat the cake.. let it sit out for an hour to settle and then pop it in the fridge if I am not going to frost it right away. Wrap it tightly with plastic wrap and let it come to temp before frosting it.

What's in your truffle filling? is it just ganache? If so then it's fine to leave it out and you wouldn't have to put it in the fridge, but I probably would. Usually I don't bake until 2 days before the event.. but an extra day won't ruin your cake.
