One of the most popular Crumbl tester cookies in 2023 was the Skillet Cookie. This cookie is described as “a warm and gooey semi-sweet chocolate chip cookie, topped with a generous scoop of vanilla bean mousse and a rich drizzle of semi sweet chocolate”.
Here is a review from a redditor:
The vanilla mousse is incredibly good. The cookie texture is just like a skillet cookie you would get at a restaurant. This cookie exactly lives up to its name, and the mousse is an excellent ice cream substitute. I think they nailed it with this one, I just hope they don’t reduce the mousse amount.
