You will LOVE the silky smooth, light consistency and buttery flavor of this Swiss Meringue Buttercream frosting recipe.
For most of the cake decorating tutorials and recipes on my site, I use American Buttercream frosting (for example, Classic Vanilla Buttercream). American Buttercream recipes are very easy to make, using simple combination of butter, confectioner’s sugar, milk, and flavorings. These are often crusting buttercream recipes that are slightly denser, sweet, and are perfect for piping.
The first time I tried Swiss Meringue Buttercream frosting, I fell in love with the ultra smooth, melt-in-your-mouth quality of this frosting. It is less sweet than American Buttercream, and has a fantastic flavor. This is not a crusting recipe, and so the Viva Paper Towel Method of smoothing will not work for this frosting, but it does pipe nicely and can be used beneath fondant (when chilled).
If you’ve never tried Swiss Meringue Frosting, you MUST give it a try at least once! The process takes a bit longer but the resulting frosting is heavenly! It may just become your new favorite!
Swiss Meringue Buttercream
- 3 sticks unsalted butter (12oz. 339g) *At Room Temperature
- 5 egg whites ( 3/4 cup, 168g)
- 1/2 tsp (2g, 1/8oz) cream of tartar
- 1 cup ( 205 g) granulated sugar
- 2 TBSP (21g) vanilla extract
- Place the egg whites, cream of tartar, and sugar in a heat proof bowl (I use my kitchen aid mixing bowl). Put this over a pot of simmering water, whisking by hand until a candy thermometer attached to the side of the bowl registers 140 degrees.
- Transfer this to your mixer and put in the whisk attachment. Whip on medium high speed until it reaches stiff peak stage This could take about 10 min. The bottom of the bowl will cool off . The mixture will become fluffy and glossy.
- While the meringue is beating, cut the butter into tbsp sized pieces.
- When the meringue is ready, put the paddle attachment on the mixer and add the butter a few pieces at a time while beating on low speed.
- Add vanilla
- The mixture may look like it is separating after you add the butter. Don’t worry, just continue beating on medium-high speed and it will become smooth again.
- You can use immediately ….refrigerate in an airtight container for 5 days or freeze for 1 month. If frozen, bring to room temp and beat with paddle attachment on low speed until it is smooth again…..3 to 5 minutes
