I'm trying to decide about flavor for my son's groom cake It' s gonna be shaped like a tree stump with gum paste fish hooks and shotgun shells. I was thinking about a carrot cake that would be stacked about 10 inches highed and covered in brown fondant for tree bark. Do you think the traditional carrot cake recipe would be too soft for fondant covering?

Also, has anyone ever heard of a carrot pound cake?

I have a dense carrot cake, not quite a pounmd cake, that I covered in fondant. Just a 10" two layer round, but it certainly did not "wilt" under the fondant. Used a cream cheese buttercream as filling and crumbcoat. Actually the crumbcoat was more like an "overcoat" because I liked the cream cheese buttercream.

It is definitely fine. I've done it before. Just make sure you add supports in between.

Thank you both!
