Just a question, I'm not making a castle cake, but I am curious how you guys make the towers? I was thinking of making one just for fun, but the round twers with the pointy hat things just stump me.

I used paper towel rolls covered in fondant. The pointy tops are upside down sugar cones. I used cake cones also.

Any ideas for something totally edible?

pastillage or rice krispies

DEE DEE DEE
Didn't think of rice krispies, GREAT idea. Do they sit on the cake ok without support?

I used rice krispie treats covered in fondant and an icecream cone for the top.

I took ice cream cones and glued the ends together with royal icing, making four of these. For the turrets on the top of the cake. I took three more ice cream cones and carved them 3 different lengths, covered in BC and then fondant. I wrapped 7 sugar cones in BC, and then fondant and used RI to glue them on the other turrets.

You could use a stack of oreo cookies covered in fondant. Yummmm!
