OMG, Mish, that's such an awesome site! Thanks for sharing it. Someday when I ahve more time, I'll be trying some of those recipes and techniques!
Canuck, like Alix said, there are a lot of the recipes you're looking for in our forums. Most likely you'll find them as cakes. Any cake recipe's cooking time can be adjusted to make cupcakes.
If you find some recipes you're interested in and have questions, let us know. We're happy to help!
