This popular American dessert is a light, airy sponge cake made from egg whites, cream of tartar, flour, sugar, vanilla extract, and salt!
You'll need a few ingredients to make this easy recipe, so round them up and let's get started!
Combine half of the sugar, flour, and salt. Sift them together 5 times.
Whip egg whites on low speed until frothy, then add cream of tartar and vanilla extract, and increase speed to medium.
Add remaining sugar, whipping on medium-high speed until stiff peaks form.
Gently fold the flour mixture into the egg whites 1/4 cup at a time. Sift the flour mixture as you add it.
Pour batter into tube pan, smooth it out, and use a knife to break up air bubbles around the pan's exterior and interior walls.
Bake for 28-30 minutes, then remove it from the oven and turn it upside down to cool.
Turn the cake right side up, loosen it from the pan with a knife or spatula, and invert it onto a serving plate.
Slice the cake with a serrated knife and serve as is or with fresh fruit, whipped cream or other toppings.
