I sculpted a 3D letter "M" for a groom's cake im doing that has to stand up right on the cake. I molded the RKT around dowels to make it stick in the cake. But I think I used too much marshmellow or either didnt push it together hard enough. Does anyone have any ideas of how I can make it more sturdy? One idea i had was to use poured sugar and coat it in it....would that even work? could I still ice and fondant it then? I dont care if you cant eat it...just need it for the look. Please help

you could make the ganach that alot use under fondant covered cakes. Or you could cut out some foam core for the M to lay on to help support it, it looks quite large.

it is quite large... it's about 9 in tall and 12 in wide. I would love to ganache just so i could eat it!! haha, maybe I'll just make a new one so i can eat this one with ganache[/quote]

why not just use styro foam?

ha, true...why didnt I think of that! Well, I would like the "M" to be edible if possible though. The last cake I made with RKT everybody chowed down on it too and said it was delicious. Guess it would be a nice touch for the kiddo's at the wedding. I made more RKT using less MM and pressed them (with all my might) into a sheet pan. Im going to let it freeze and then cut out the letter. Hopefully it will work. But this whole cake has kinda been a 3rd times the charm deal. If you look up murphy's law im pretty sure you see this cake. I'll let ya know how it goes...thanks for the help!
