How to make The Easiest Marshmallow Buttercream Ever


During an attempt to make a birthday cake late at night that couldn't have eggs in the icing and didn't use that nasty crap from a can, I stumbled upon this recipe. It's so simple and so good.

  1. Put a saucepan over low heat. Add milk and marshmallows and stir intermittently until it's all melted. Set aside to cool.
  2. Using an electric mixer, cream the butter until light and fluffy. Slowly drizzle in the marshmallow mixture and the vanilla extract while the mixer is still going and whip until creamy. This is also where you would tint the icing whatever color you like.
  3. Frost your cake immediately. Make sure the cake is fully cooled, though -- this icing is prone to melt on a warm cake.

This recipe makes enough to ice a 9-inch, two-layer cake. It'll set up pretty hard in the fridge -- if you plan to refrigerate the iced cake, allow it to come back to room temperature before service.

(For the record, the cake I put it on was this recipe.)

    Sounds like a good alternative to those sickly sweet sugar icing! It's not too sweet, is it?

    No -- it's got just enough sweetness so that it doesn't taste like straight butter, but mostly it's just richly creamy. Went perfectly with the chocolate cake.

    Yum! I've been trying to find a buttercream or buttercreamesque recipe, that was a little less involved than Alton Brown's. I should have known to check with you!

    I just tried this recipe out tonight and I am not impressed. The icing I made, following this recipe exactly, turned out completely different from what was shown in the photo. The consistency was more like a glaze and after attempting to whip it for about ten minutes I gave up. Please consider this before wasting your ingredients.
