Simply Perfect Chocolate Swiss Meringue Buttercream

Did you see my Simply Perfect Chocolate Cupcake recipe?  You didn’t think I’d leave ya hanging with the frosting recipe, did you?  Aww, I’m not one to hold back, believe me.  😉

It’s over here in a separate post, just for organization and indexing purposes!

Simply Perfect Chocolate Swiss Meringue Buttercream

Swiss Meringue Buttercream takes a little bit more effort than the powdered sugar + butter American variety, but it’s totally doable, even for a beginner, and the flavor payoff makes it all worthwhile.  If you’ve never tasted it before, you are not going to believe it!  Every time one of my friends or family tastes it for the first time, they’re always like “what IS this???”

The hardest part is warming the eggs and sugar together, and that’s not really a big deal.  I do it right in the bowl of my stand mixer, over a pot of simmering water.  Just whisk it continuously for a few minutes, and then rub a drop of the mixture between your thumb and forefinger.  Does it feel gritty?  If so, keep whisking for another minute or so.  If not, go ahead and put the bowl on the mixer and start whipping!

You’re going to whip it until it’s completely cool.  It will look (and taste!) a lot like marshmallow.

When there is absolutely no hint of warmth to be felt, start whipping in the softened butter.  Just a tablespoon at a time!  If it starts to look curdled, don’t panic.  Just whip, whip, whip, and it’ll come back together.  I promise.  😉

Fold in the melted chocolate, and you’re golden!  I melt mine in the microwave, stirring after each 20 second interval, until it’s completely smooth and velvety.

This frosting would be great on just about any kind of cake or cupcake.  I especially love it on a vanilla cupcake, but my four-year-old prefers chocolate on chocolate.  Here’s the recipe for Simply Perfect Chocolate Cupcakes.  They are easy-peasy to throw together, super moist, and deeply chocolatey.  You’re going to love ’em!

Recipe Notes

If the egg whites and/or the butter are slightly too warm, the buttercream may be runny. This can be easily remedied by placing it in the refrigerator for 20-30 minutes, then whipping again.



*Enough to ice (2) 9-inch diameter cakes, (1) 9 x 13-inch sheet cake, or 2 dozen cupcakes
