Step 6: Assembling the Cupcake
Before you begin, take the sorbet out of the freezer to soften a bit, so it's easier to work with.
First, either put your awkward circles of chocolate cake into the bottom of the cups, or get out your awesome cake pop 'batter' and cram some of that in. (Again, please don't do this the way I did. It was way too hard.)
Next, cover the cake with some of your softened sorbet, and pop it back into the freezer to harden a bit.
When you're ready to serve the cupcakes, break out the frosting and frost them just before serving. The reason you want to wait until you're ready to serve them is because if you frost them with a standard buttercream and put them back into the freezer, you'll end up with frozen, hard icing.
So there you have it. Go forth and make cupcakes!
