Is it possible to make Kief frosting?

Hey everyone is it possible to make a keif frosting for my canna-oil brownies? And how should I go about this?
I'm looking to either make the frosting myself and find a way to add the keif to it after I bake the brownies. Or I could buy a thing of frosting and add to it.
Or would carmel work better?
Any and all help or suggestions are greatly appreciated!

It is possible just to throw some kief into the frosting and stir it up...but...Id try a small bit 1st. It'll probably be yucky
