The list of foods that are made more awesome by being stuffed in croissants is pretty immense and far-reaching, from the sweet (chocolate, almonds, cream cheese) to the savory (ham, cheese, hot dogs).

So I was pretty sure that a buttery blanket of croissant dough would have the same awesomeness-enhancing effect on leftover birthday cake (or, in this case, a leftover birthday season cupcake, from the delectable Jubilee Cupcakes).

And guess what? It turned out pretty good. While the frosting can melt out a bit and get messy, it does lends an extra-buttery richness (and a nice color contrast, as mine had pink frosting), and the cake crumbs give it an extra-carbohydratey boost, perfect for carbo-loading if you're about to run a marathon (or, you know, just a tasty snack if you're not).

Want to give it a try? Here's how I did it.

Birthday Cake-Filled Croissants

Ingredients

1 leftover cupcake (or, 1 leftover slice birthday cake)
1 package ready-to-bake croissants (you know, the kind in a roll)
Extra butter, to brush on top (if you're into that)

Directions

Preheat oven to the temperature directed on the croissant package.
Unroll the croissants. In the center of each, place a chunk of birthday cake, crumbled up (with frosting!). Roll them up, or (as I did with some of them) form the dough into little dumplings around the cake.
Place on a sheet. If desired, brush tops with melted butter (why not?).
Bake for the time specified on your croissant package. When you open the oven, you may discover that the frosting has oozed a bit out of the sides, but don't worry--plenty was probably able to melt into the croissant dough. Plus, once it cools just a bit, you can kind of scrape off the oozed bits and eat them (if, like me, you have no manners, that is).
