Foolproof Swiss Meringue Buttercream Frosting Recipe

I’ve heard some people say that the only reason for cake is to hold up the frosting. But the typical American buttercream frosting is horrible! They’re often striking colors made with a metric ton of nearly inedible food coloring or if not they’re just a massive, cloying, clumsy glob of diabetes.

They may look great but they’re not worth eating.

If instead, you’re looking for a delicious, silky smooth frosting to top that cake or cupcake, that will work beautifully with your piping bag to make pretty, elegant designs, look no further.

The Swiss meringue buttercream is a classic frosting that, unlike the American buttercream, actually tastes good. It is of course, mostly due to the incredible amounts of butter, but it can also be easily modified with different flavors.

Because of its meringue beginning (whipped egg whites and sugar), the Swiss meringue buttercream has a beautiful silky feel and a shiny exterior. It holds up very well and pipes like a dream. If you see a cupcake on my site, it has this frosting on it.

The caveat is that you’ll never truly get a really bright white color. Butter is yellow and even if it lightens up during the beating, it still retains a very slight yellow tint. To the naked eye, it looks white unless you have store-bought bright white frosting to compare it to. But try a scoop of that so-close-to-white buttercream and a scoop of that store-bought brilliant white frosting and you’ll discover that you’re perfectly happy with so-close-to-white.

I think people are afraid of this method because it’s just a little more involved and uses a process that some people may not be familiar with. It requires heating up the sugar and egg whites in a “bain-marie” but that’s really nothing more than setting a pan of simmering water on the stove and placing your mixing bowl into it.

Give it a whirl. Try it once and it will become your favorite in no time. And then you can throw around phrases like “bain-marie” and impress your guests with both your French and your mad baking skills.
