I’m sharing this post in connection with my favorite gluten-free chocolate cake recipe (pictured below) because I thought this frosting totally deserves its own page.
This white frosting is a simple Italian buttercream from whipping meringue with butter and warmed sugar.
It’s creamy and silky smooth with a lightly sweet, vanilla flavor. Perfect for piping or cake decorating! Best of all, it’s more stable than traditional buttercream at room temperature, making it perfect for celebrations.
Make Ahead and Storage Tips for White Frosting
If you’re not using the buttercream immediately, keep in mind that you will need to give it a quick whip to get the silky smooth consistency. It can be refrigerated for a few days. When ready to use, all it to come to room temperature.
White Wedding Cake Frosting Recipe
- stand mixer with whisk attachment
- 4 large egg whites room temperature
- 1/4 tsp cream of tartar
- 1/4 tsp sea salt
- 1 1/3 cups granulated sugar divided
- 1/3 cup water
- 16 ounces unsalted butter (2 sticks) room temperature
- 1 tsp pure vanilla extract
- Completely clean and dry your stand mixer bowl and separate the yolk from the whites, being careful not to mix the 2 together (fat inhibits meringue).
- Whip: Beat the egg whites, cream of tartar and salt over medium speed until fluffy, about 1 minute. Slowly sprinkle 1/3 cup of sugar and continue whisking on medium speed until soft peaks form.
- Boil: Meanwhile, place the remaining 1 cup sugar in a small pot with 1/3 cup water over medium-low heat. Stir and cook until the sugar melts and becomes clear. Raise the heat to medium-high and cook until temperature reaches 235 to 240°F. Tip: Use a spoon to drop some of the liquid into a cup of cold water. When the sugar can be formed into a soft ball, it's ready for the next step.
- Drizzle: Immediately pour the hot sugar into the meringue in a slow and steady stream while mixing on medium. Continue mixing until the bowl is no longer hot to the touch and the meringue is cool.
- Butter: Use a butter knife to cut the butter into the meringue in small pieces, incorporating as you mix. Add the vanilla and mix until combined and silky smooth. Use the frosting right away or refrigerate for up to two weeks.
