Does anyone have any idea of how to attach a rice crispy handle to a cake. The rice crispy piece will be covered in fondant. I am making a hotwheel tire cake. It is going to look just like the tire carrying case so I need to attach the handle to the top. It will be laying down too so I know it will be a little heavy. Any ideas would help. Thanks

Use melted chocolate - it's a great "glue" and sets up very quickly.

How about toothpicks, or thick spaghetti, or bamboo skewers.

I use bamboo skewers when I need to support a weight. Otherwise, melted chocolate is good to use.
