Make the right consistency rice krispie treats? I bought some treats already made to play with. They were very soft so I shaped it and let it set out for several days. It was still too soft so I decided to put it in the oven. I figured it would either melt or get hard. It got rock hard. I covered it in fondant and it got soft and fell apart before I could even finish covering it.
I think if you slather a thin coat of RI over it will help harden the cereal treats.I made one last week and it was hard the next day.
I've heard that omitting the butter in the recipe also helps.
I use ricekrispies frequently and never add the butter. Covering the ricekrispies with RI does make a good hard surface. I've found it needs to be sanded to be good and smooth, and that's easy to do.
