Rice Cereal Treat Recipe For Sculpted Cakes And Toppers

This is my recipe for making rice cereal treats for toppers and for sculpted cakes. The main difference between this recipe and a regular rice cereal treat recipe is that it doesn't have any butter and it has chocolate added to it. Butter makes RKT too soft and not ideal for sculpted cakes. The additional chocolate helps keep the RKT nice and solid so they don't pull away from the structure. 

Make sure that when you are applying RKT to a structure you have a base of melted marshmallows on the structure or your RKT will fall off. Also remember to let your RKT mixture cool for 10 minutes until it can hold it's shape before attaching to the structure. Wrap the RKT well and let cool fully before attempting to carve.

Rice Krispy Treats

Rice Krispy Treats (RKT)

One of the foundational tools of 3D cake sculpting, rice krispy treats are essential to getting shapes and forms that simply can't be achieved with traditional cake sculpting. After trying and testing several recipes over the course of my career, this recipe is my go-to for getting the job done right the first time.

    How do you “smooth” the rice cereal treat mixture after carving? Or do you coat wth chocolate or ganache before covering in fondant?

      I dont coat it with anything but you could use ganache, buttercream or royal icing

    Excited to try this. I noticed in many comments you said RKT is shelf stable for a long time. Does that still apply if it’s covered in fondant? I need to make a cowboy hat and since this is my fist attempt I want to give myself plenty of time. However if it works, I’d like to be done with it!

      You sure can! I typically would carve down the RKT first to make it smooth, then apply ganache or buttercream to make sure the fondant sticks
