Giant Cupcake

My friend Jane asked me to make cupcakes for a friend's birthday this week, but then had to change her plans.  I put the regular-sized cupcakes in the freezer for later, but didn't have room for this one.  Oh well...couldn't let it go to waste! 

I am still experimenting with the "cupcake liner" around the bottom of the giant cupcake.  My goal was to make a template but each cupcake bakes up differently, even if you measure the amount of batter, so you have to cut the paper to fit each cupcake.  If anybody has any ideas about how to make a template for the giant cupcake, please let me know.
