This classic angel food cake is the perfect dessert base for your next party. Cut the finished cake into single-serve portions for petitfours, frost the whole cake to make a sheet cake, or follow our Kitchen Note (below) to bake it in angel food pans or round pans. Make this cake yours, and don't forget to let us know how you did so.
Preheat oven to 375°. Line bottom and sides of a 13- x 9-inch pan with aluminum foil, allowing 2 to 3 inches to extend over sides of pan. (Do not grease pan or foil.) Sift together first 3 ingredients.
Beat egg whites and cream of tartar at high speed with a heavy-duty electric stand mixer until stiff peaks form. Gradually fold in sugar mixture, 1/3 cup at a time, folding just until blended after each addition. Fold in vanilla and lemon juice. Spoon batter into prepared pan. (Pan will be very full. The batter will reach almost to the top of the pan.)
Bake at 375° on an oven rack one-third up from bottom of oven 30 to 35 minutes or until a wooden pick inserted in center of cake comes out clean. Invert cake onto a lightly greased wire rack; let cool, with pan over cake, 1 hour or until completely cool. Remove pan; peel foil off cake. Transfer cake to a serving platter. Spread Lemon-Cream Cheese Frosting evenly over top of cake. Garnish, if desired.
You may also bake this in an ungreased angel food cake pan for 30 to 35 minutes or in 3 ungreased (9-inch) round pans for 15 to 18 minutes or until a wooden pick inserted in center comes out clean.
