This weekend, I made the same batter but I made 2 6" cakes. One went straight into the freezer. The other one was split into 2 layers, masked with ganache and glazed (pictured). The 6" version is just as thick as the 9" cake but I'll have an easier time maintaining my girlish figure with the 6" cake.
The happy thought is that I'll be able to thaw the other cake in a few weeks. Whip up a little ganache, glaze it, enjoy. Just like that. Easy. Piece of cake....
