I made the durable cake recipe from this site using both a chocolate and an vanilla cake. Both were not durable, they crumbled when I tried to carve them and the tops seemed to be really moist, almost wet?

After baking I let them cool then I covered in saran as I wasn't going to carve the cake until the next day. I ended up having to throw out both because it was such a disaster. (however the pieces that I ate before throwing it out were delicious).

Am I doing anything wrong here? I followed the recipe exactly.

Did you freeze the cakes? I believe a cake has to be frozen before you can carve it.

No, I didn't freeze it first. Does anyone else do this? Do I have to carve it frozen?

Freezing cakes will make it durable less crumbly while carving. I've done it so hope this helps
