looks like rolled fondant to me.......if it was poured I would think it would have adhered a little bit to the papers like these
Those definately look like rolled fondant - very pretty btw
if you want it nice and flat looking then domed cupcakes are not good. the fondant will conform to the shape of the cake.
Because it's not sitting in the zig zags of the cupcake liner, I'd say it was a circle cut from rolled fondant. It's fine to put that on domed cupcakes, just smooth the surface with your fingers once it's on. Hope that helps!

You could always level the cupcakes to make the fondant lay flat. (if you have time that is)
