espresso cup(cake)s and espresso bars

yellow cake cupcakes with espresso buttercream, with un chicchi di café, and spongebar squarecakes of the same nature, only with less buttercream for the sugar overloaded. okay, not truly a sponge, but very light and fluffy, yet nicely moist and sweet. for those of you who are tired of the cupcakes, have no fear, i've finally found a yellow cake recipe i like (footnote explains how to make it a yellow cake). for those of you who are aren't saturated in buttercream yet, there's always chocolate, carrot, pumpkin, coconut, etcetera, etcetera, wheeee!

the buttercream was inspired by oslo foodie's recent foray into baking, only i used a non-french buttercream recipe (which is egg based), as frighteningly enough, a tray of eighteen eggs doesn't last very long in the cupcake kitchen....come to think of it, neither do the cupcakes.
