This extra fluffy white cloud icing is a light, bright, and not-too-sweet frosting perfect for cupcakes and cakes. Made without butter or powdered sugar, it's fluffy and stands out for its pristine white color.
In a clean bowl free of any grease, beat the egg whites and salt on high speed using a stand mixer until foamy.
With the mixer running, slowly add the granulated sugar and beat the mixture until soft peaks form.
Bring the light corn syrup to a boil over medium heat in a small saucepan, then remove from heat.
Slowly pour the hot corn syrup into the egg white mixture while mixing on high. Beat until stiff peaks form, about 5 minutes. Add vanilla extract and mix to combine.
Use the icing immediately to frost cakes or cupcakes.
Notes
This white cloud icing is best used fresh as it sets up quickly and becomes less spreadable over time. For perfectly white frosting, no butter is used, avoiding any yellow tint.
