Sorry about the title. I'm about to attack the biggest cake I've done. I'm going out of town and have to finish it Thursday or Friday morning for a Saturday morning party.
Today is Wednesday. I am baking and cooking my cakes. I then plan to freeze them for a bit so they are easier to layer. I will then frost with a coconut buttercream (Crisco and sugar and extract) freeze until crust and then wrap in saran wrap.
On Thursday or Friday morning I am going to drizzle with chocolate Grenache and from that point on the cake needs to remain at room temp. I will deliver to the home and then Saturday the cake will be delivered to the party.
Will this work? If I freeze everything will that reduce the amount of time it can be left at room temp?
