I've seen it described that way, but honestly, after actually eating the gray stuff...well, what we had did not resemble any cookies & cream mousse we've had before. Didn't taste like it, and no cookie flavor, no cookie bits in it that we could determine, no cookie base or anything like that...other than the perfectly round little crunchy decors on top that might be construed to be crunchy like cookies. But they didn't taste like cookies, either. The decors were kind of tasteless. The mousse itself was a chocolate-like flavor, but not very strong...almost like a flavored whipped cream. Just not a very flavorful dessert. It was OK, but like I said, not good enough to want to order in the future. JMO, of course.
