Key lime frosting does not follow the laws of physics.
We use the same buttercream recipe for almost all of our buttercream frostings. Without any additions, such as vanilla custard or cocoa or caramel, it will frost about 24 medium cupcakes. Sometimes a few less – the Pirate Vanilla Cupcakes we made on the 19th took more frosting than usual. Sometimes a little more – when we frost the Orange Creamsicle, it always seems like we can frost 25 or 26 before the frosting runs out.
But 36? That’s a lot more cupcakes than the batch should ever frost. But every single time we make the key lime frosting, it never seems to run out 35 or 36 cupcakes.
Well, you say, you must be adding a lot of key lime curd to that frosting? Nope! Four heaping tablespoons.
Okay, well, maybe you’re adding a lot of air? It doesn’t get mixed any longer than any other frosting – it certainly doesn’t get mixed longer than the Vanilla Custard frosting, and we also use the same amount of custard for that frosting as the Key Lime.
So obviously, we are forced to conclude that Key Lime Frosting breaks the laws of physics. Since it does so deliciously, we’ll keep making it until the universe tells us not to!
What do you think, cupcake fans?
I think being delicious trumps any fru-fru silly laws of physics you speak of.
The pirate cupcakes are spectacular!
