3cups powdered sugar, divided into 1.5 cup portions
12egg whites
1.5teaspoons cream of tartar
1/4teaspoon salt
1 teaspoon vanilla extract
Fresh whipped cream and berries
Instructions
In a medium mixing bowl sift together 1 cup cake flour with 1 ½ cups powdered sugar. Set aside. Preheat oven to 350 degees F.
In a large mixing bowl beat together egg whites, salt, cream of tartar and vanilla. (About one minute). Once the egg whites get foamy slowly add 1 ½ cups powdered sugar. No more than a ¼ cup at time. Once combined mix until the egg whites get a nice glossy finish and form stiff peaks when you lift your mixer. This will take a few minutes.
Grab your rubber spatula and gently fold your flour & powdered sugar mixture into your egg whites about a quarter of the mixture at a time. Be gentle during this process as you want to keep the air in your egg whites.
Scrape the mixture into an un-greased tube pan and bake at 350 degrees for 45 minutes.
Remove the cake from the oven and immediately turn it upside down onto the feet of the pan. Cool for 1 1/2 hours.
Use a thin knife to cut around the edges and bottom of the pan. Gently drop the cake out of the pan onto a cake stand or plate. Top with freshly whipped whipping cream and berries.
