I want to make a witch's cauldron for Halloween but I want to make it out of RCT instead of cake since there is already going to be cake at the party. That way I will also be able to mold it straight in the KA bowl and get the perfect shape without having to carve. I have however had RCT go soft and crumbly on me in the past. I want to make sure the RCT is a solid as possible so that the cauldron shape holds together.

Is there a special recipe for RCT which is used in cake construction, or is it just the regular recipe which I have used in the past?

Less butter will make it harder but also less tasty....

I've used the regular recipe to make a golf ball. I used the ball pan to mold it and let it cool and harden then took it out of the pan. Can't remember who it was now, told me to crush the rice krispies first.

It is harder I am looking for so that is a good tip, thanks. Do you omit it all together or just use half?

I agree with the crushing of the krispies. Are you planning on letting them eat them or just for a dish for display?

I used crushed to make my elmo, just for show, and it worked wonderfully,

Also I didn't use a lot of butter either.

Post a pic when finished, I would love to see how it came out.
Good Luck.
