My cakes are all ready to go, but they are still frozen. I'm using frosting (store bought) for filling and crumbcoat. can I fill and crumbcoat while they are still frozen or do I need to wait until they defrost a bit? thanks so much you all are so helpful!!
I would wait for them to defrost. That leaves less error for bulging later. I'm sorry I'm not much help on this.
Wait for the cakes to defrost! If you put that icing on, the moisture from the cake is going to come through the icing and you're icing is going to sweat.
I crumb coat my cakes frozen the night before I need them. Then by morning they have crusted over and if there is any bulging you can fix it.
Just pop those babies in the microwave for about 30 seconds. Brings em' back and beautiful because the ice crystals melt and add moisture. Then crumb coat. Just a little something I do when I can't wait. I have iced somewhat frozen too.
I do this all the time. I fill and crumb coat while the cakes are frozen, and then let them sit (and sweat) until the crumb-coat crusts. It can take a few hours for it to crust -- depending on the size of your cakes.
I also do this for sculpted cakes (frozen cake is MUCH easier to cut and crumb coat).
I crumbcoat and fill my big cakes (14" and up) while they are frozen to keep them from breaking when I put the second layer on. It doesn't work as well and I sometimes end up with wet spots in my crumbcoat, but I prefer that to having a wedding cake broken on the floor.
If you do, be sure to let it sit long enough to be completely thawed and crusted over before you put your final coat of icing on. If you don't, the icing probably won't stick.
thanks for this post I always wanted to try but have been too skeptical about it and felt dumb asking.
