Last week, something magical happened: upon returning home to the Cakespy Headquarters after running some errands, we found the most gorgeous box of cupcakes on our porch. Magic!

The parcel was from Seattle's newest custom-order cupcake business, Look Cupcake. Based out of a commercial kitchen on Lower Queen Anne, owner Rhienn Davis takes a unique slant on the cupcake trend by looking inwardly--literally--by specializing in gourmet, filled cupcakes.

Our assortment included three flavors: the Feather Boa (coconut cream cake, mojito cheesecake filling, vanilla buttercream, coconut garnish); the La Nina de Chocolate Diablo (spiced mexican chocolate cake with kahlua especial swiss meringue buttercream); and the A Formal Affair (vanilla cake, bittersweet ganache filling and whipped truffle frosting).

These cupcakes were--to put it mildly--crazy delicious. But even more than the fillings, what impressed us was the frosting. Silky, buttery and absolutely luxurious, it seemed different a lot of other cupcake-frostings we've tried. What gives?

Turns out, they were topped with what is known as Swiss Meringue Buttercream (and in the case of the chocolate frosting, ganache whipped in, which only added to that luxurious texture).

So what is Swiss Meringue Buttercream? Happily, Rhienn (aka the "Cliff Clavin of buttercream") was able to explain:

The difference between meringue buttercreams (there are several - Italian, Swiss, French - every European country thinks they know best, apparently,) and regular "American style" buttercream (what we think of as a more "crunchy" frosting) is as follows:

American buttercream is just butter (sometimes a little cream cheese) and TONS of powdered sugar mixed together. The result is that intense, super sweet, sometimes a little gritty, frosting. I make a great one with fresh ginger grated into it. Mmmm!
(Pick your European country) Meringue buttercream is made by dissolving a relatively small amount of granulated sugar into egg whites, whipping it into a meringue and then adding the butter. They're smoother, creamier and less over the top sweet. They also stand up better in heat, which is awesome for those of us that do seven million weddings in the dog days of summer.

So there you go--unexpected free cupcakes, and an unexpected lesson on various different types of frosting: we'd call that a sweet treat, indeed.
