You should be able to use any recipe you already have in your silicone pans. Check to see if you need to grease them first - I can't recall.
Do beware that unless you have the kind with a frame on the edge, you need to place them on a cookie sheet as they are too flexible to lift without support from the edge or underneath.
They are pretty cool. Getting food out of them is much easier and cleaning them is quite easy, too.
Have fun!
