Everyone thinks that I got the cake from a professional bakery when I use this buttercream. It is fluffy and not too sweet, perfect for wedding cakes or layered with pound cake and fruit preserves. Tightly-wrapped, it can be frozen for a month or two. Makes enough to frost an 8-inch layer cake.

Ingredient Checklist

Directions

Instructions Checklist
  • Pour egg whites into the bowl of a stand mixer fitted with a whisk attachment; beat on low speed until foamy. Add cream of tartar, increase speed to medium-high, and beat until stiff peaks form.

  • Combine sugar and water in a small saucepan over medium heat; bring to a boil. Cook until syrup reads 240 degrees F (115 degrees C) on a candy thermometer or until a small amount of syrup dropped into cold water forms a soft ball that flattens when placed on a flat surface.

  • Increase mixer speed to high and pour syrup in a slow and steady stream down the side of the bowl, beating until meringue is no longer steaming, 2 to 3 minutes. Beat in butter one cube at a time until buttercream reaches a soft and spreadable consistency, 3 to 5 minutes. Beat in vanilla extract.

Cook's Note:

For a chocolate hazelnut buttercream, beat a whole container of chocolate hazelnut spread (such as Nutella(R)) into the finished buttercream. It is delicious on a rich chocolate layer cake.

Excellent recipe. A lovely light and fluffy buttercream, very buttery with a very nice sweet finish. The only changes I made were to temperatures. Egg whites were cold, butter was room temp. I find this helps hugely in getting stiff peaks and cuts your post butter mixing time down. If your butter is too cold the buttercream will crack and you'll endup needing to warm it anyway. Read More

I infused the water with a white tea before I mixed in the sugar. It made for a delicious, floral frosting. Read More
