Awesome guys, thanks!
Hey I came up with an idea I wanted to try for cookies, it'll be a filled cookie. The crust will be shaped like a bottle cap only bigger, with a flaky crust, inside, I want orange mousse. This is were the problem comes in. To finish off the cookie, I want to pour icing over it, and let it harden, almost like cinnamon roll icing. The problem is, Would the Mousse melt if I pour hot icing over it? And is there a way to make a sort of glaze-like icing, that will go on at room temperature and then set up? Any help would be appreciated.
