I'm making a 4" dummy "smash cake" for a friend. She wants to save it because it's for the 1st anniversary of the birth/death of her baby who was stillborn.

Now... I was thinking of using royal icing and just letting it dry completely (on a styrofoam "cake" of course) but then I started to worry that even completely dry royal icing would attract ants! EEK... we have a major ant problem in this area, and that's the last think I'd want to happen to this cake!

Does anyone know if dry royal would attract ants? If so, is there anything else I could use to frost the cake? I don't think she'd want it to be covered in fondant, and I don't have time to order any special "dummy BC" because the cake is for this Saturday.

Any ideas?

I use my regular BC icing on styrofoam and it hardens like concrete. I've had some cakes for about 2 years and never had a bug at all.

Well, I usually only use SMBC... I guess I could try making some regular BC but I really hate working with it.

But the no bugs gives me hope. Thanks!

Any others?
