This versatile frosting comes together quickly.
Why This Recipe Works
This traditional (European) buttercream frosting recipe is made by heating eggs and sugar over a pan of simmering water, then removing from the heat and whipping in butter. If it becomes runny, simply plunge the bowl of frosting into ice water and whisk the buttercream until it has thickened. If, on the other hand, the frosting appears curdled, wrap a hot water-soaked towel around the bowl to warm it and whisk the mixture until smooth. We used whole eggs, whipped until airy, to give our buttercream frosting recipe a light, satiny-smooth texture that melts on the tongue.
