This was more layers than I've ever put on top of one another at once. I think the cake didn't collapse upon itself because all the layers were uniform in size; if I'd done tiers (which I've tried and suck at), it would have tipped over sideways or imploded.
But it's very routine for me to push my own limits with my baking and attempt things that are, realistically, way beyond my actual skill level. Despite being bigger than normal, this cake consisted of things I'm practiced at-- Swiss meringue buttercream, ganache, marshmallow fondant, and so on are all things I've made numerous times. And, honestly, I cheated on the actual cake and used mixes because I didn't want to be in the kitchen for three days straight. So it wound up being pretty successful despite combining a lot of different elements.
