Used Mousseline recipe for frosting and cookies and cream (crushed Oreos) mousseline for the filling. This was quite delicious but because it does not "crust", smoothing it out was a learning experience. 10in square chocolate cake, and used melted chocolate chips/cream to form cross design and initials on the top. Ribbon was pinned in place and a second layer was added because the blue frosting was seeping/staining the white stripe in the ribbon.
