Here's a two-layer 6" chocolate cake just for the birthday boy with Gotham city and the Bat Signal decorated in fondant. For his Bat-friends, there were vanilla cupcakes filled with whipped chocolate ganache and frosted with birthday buttercream and topped with a fondant Batman logo.
He had a small party at school, so I made sugar cookie pop favors using the same fondant logo and royal icing :)
Happy 5th Birthday Aiden! :)
