Here's a recipe that might outshine the marshmallow-graham cracker-chocolate cupcakes: key lime cupcakes from Bon Appetit. I brought them into the office to celebrate a wave of employees passing their LEED tests (that means that the public thinks we're "green" architects - we already were, but now there are initials that supposedly prove it - any excuse for a party).
Wow. I used real key lime juice, and now I know that you can juice those little guys with a garlic press. There's a mix of key lime zest and regular lime zest in the batter and in the frosting.
I added a graham cracker crust (the same one as in the s'mores cupcakes), and topped the batter with extra graham cracker crumbs. The cake is dense, but velvety, and tastes more like lime than I thought it would.
One batch was made with green food coloring, another without. Without wins, hands down.
(Edited to add the link to the recipe. It's also at epicurious.)

They look GOOD! Where can I go for the recipe?

Gaahhhhhh....there is a house near me that has Key limes growing on a tree in front of their house, and they do nothing with them, and don't mind people picking. I think I need to make a trip. Tonight.

Yum! Adding zest makes such a huge difference.

They look delicious! By the way, I did hold a moment of silence in my kitchen for your mixer and I have to admit to fantasizing about mine breaking down so I could buy a new red one too! I only whispered that so my old mixer couldn't hear. After all it is a member of the family. My son named it Charles after the little dog in "Charles of the Wild" by Anne and John Hassett when he was two.

Hi again!
I believe I deleted an e-mail from you without reading it. I didn't recognize the address until I was getting a cup of tea and light dawned! Very sorry! If you would resend the message, I promise not to be so quick with the delete button. I do enjoy reading your blog very much.

Oh Chelle, reading your blog makes me hungry. And it makes me wish I lived right around the corner from you. Not only because I could more often enjoy your wit and wisdom, but - selfishly - also because I could enjoy the rewards of your baking! YUM!
