When I woke up the Saturday morning (at the crack of dawn because the kids were running around), I discovered my aunt had left the window open in the kitchen, and the freezing cold night/morning air had dried out the cupcakes a bit (initially I thought they might be frozen). This was a little disappointing, but they weren't too bad. I mixed some cream cheese frosting, covered the cake in it, and then rolled out white fondant to cover the cake with. The fondant amused my cousins to no end; I gave them each a small piece to play with. I think I may have inspired some future bakers. I really need practice when it comes to covering cakes in fondant. There was a pretty large crease in the back of the cake. Given that this was only my 3rd attempt at a fondant-covered cake though, I'd say it wasn't too bad.
One thing I would do over would be to pipe a ring of buttercream around the edge of the cake layers before filling it with the mousse, which was way too soft and got squeezed out of the cake with each additional layer that was put on top. I should have thought to do this in the first place. I also can't wait to take a class to improve my fondant capabilities. I'd love to do more cakes in addition to cupcakes.
