Are their instructions on this site that will tell me how to create rice krispy molds and if the recipe is altered? I want to create castle towers but am not sure how to do this and how to anchor them so they do not detach from the cake.

The recipe is the same as far as I know. That's what I used when I did it. It is suggested that you send it through a food processor, or else it could get pretty lumpy, but I found that a couple layers of fondant helps immensley with that.

I molded my castle towers in a tall kitchen cannister (it is hard plastic or acrylic I think) coated with butter. They slid out pretty easily. You could probably use sou cans or something smaller, depending on the size you need. I used the normal recipe and just coated them with buttercream to even out the surface and then applied the fondant.

I didn't do anything to anchor them, I just assumed that putting buttercream at the seams would do the trick. I was wrong! They separated from the rest of the castle during transport, so I'm curious to see what suggestions are out there. I know that some brilliant CCer here will have a solution.

HTH!!

I form my castle towers by cutting out pieces with a cookie cutter and pressing them down before unmolding, then stack them. It's a bit time consuming, but the tower is good and solid and fairly smooth.

I build the towers onto a bamboo skewer or sharpened dowel. Then, I hammer the dowel through the cake (if it's an upper tower), any boards and all the way through the base board. There's a princess castle in my photos. All the towers, including the top 'tier' and tower are made of RK treats. Only the bottom and middle tiers are actual cake. It's all iced in buttercream.

Edited to add: I adjust the recipe so there's slightly less marshmallow and more rice krispies. I also add half or less of the butter called for. Makes for a firmer object. Too much marshmallow and your object will be flimsy forever. It will never firm up.

I haven't done it.......but If I was going to I would do what I usually do to the r.k. when using them to make something that I want to be sturdy. ......first of all......crush the r.k. .......I do it with just my hands, this makes the pieces smaller and makes it more compressed and sturdy in the final product......then I would omit all of the butter in the recipe...it makes them not dry up as hard and can make things (like towers) fall over.......then just add melted marshmallows to them mix them up and I would find something that is the shape and size you need (for my spongebob cake, I used a regular water glass out of my cupboard to mold the r.k. treats into squidwards house.......maybe what you'll want is a pringles can or even a couple soup cans)......then mold them........if you use a can or something hard....line the inside with plastic wrap and make your life easier!!! If using a pringles can you could probably just cut it off the r.k. once the're hard! Anyhow.......if you want to you could always shove a couple skewers into the "tower" before it sets up and then once it's hardened it has something to stick into the cake. hope that helps!
