Preparation Steps

• Preheat oven to 350°F (175°C). Grease and flour a 10-inch tube pan.
• In a large bowl, sift together the flour and sugar. Set aside.
• In a separate bowl, beat the egg whites with cream of tartar until soft peaks form. Gradually add the sugar, beating until stiff, glossy peaks form.
• Gently fold the dry ingredients into the egg whites, being careful not to deflate the mixture. Stir in the vanilla extract.
• Pour the batter into the prepared pan and bake for 35-40 minutes, or until a wooden skewer inserted into the center comes out clean.
• Invert the pan and let the cake cool completely before removing from the pan.
