Bad Birthday Baking: a mini-meme for Dean's birthday!

Prompt: It's Dean's birthday. One year, while living in the bunker, Dean is off in the garage working on the Impala because he wants to relax. But then he notices that he hasn't seen Sam all morning, and Sam usually comes in at least once just to hang out. So he goes in search of his brother and eventually finds Sam in the kitchen, where Sam is trying, but completely failing, to make a birthday cake. Because we all know Dean is the real chef in the family.

Your task is to create a fill for this one prompt. cowboyguy sent it my way and, instantly, I was pulled in 4 different directions for how this could go. I'd love to see what other people do with it as well! Create art or write a short comment fic based on this prompt. Post your creation as a reply to this post on January 24. Be sure to comment and enjoy the other fills as well!

Will a demon interrupt the festivities? Is Sam's mind on something other than the recipe? Will they just jump in the Impala and go out for pie instead? Let's see how many different, failed birthday cake attempts we can get for Dean. Bonus points for hurt/comfort and super bonus points for sneezing (though neither is required). Will there be angst? Fluff? Pr0n? You decide!

Note: Before the 24th, all comments to this post will be screened so that no fics/art accidentally slip through before Dean's birthday. I will unscreen and reply to whatever comments/questions get posted.
