In "American" cuisine, there is a baked good called a brownie, which is peculiar because it exists at a kind of intersection of cookies (biscuits), cake, and fudge. Brownies often have a cookie-crunchy exterior, and the moist interior of a fudge cake. It's an in-between confection.
Does any other cuisine have this kind of liminal baked item, that crosses over cookies and cake? We couldn't think of any, so turning it over to Seasoned Advice to find one.
