Lemon Meringue Angel Cake Recipe

Place egg whites in a large bowl; let stand at room temperature for 30 minutes. Sift 1/2 cup sugar and flour together twice; set aside. Add cream of tartar, vanilla and salt to egg whites; beat on medium speed until soft peaks form. Gradually beat in remaining sugar, 2 tablespoons at a time, on high until stiff glossy peaks form and sugar is dissolved. Gradually fold in flour mixture, about 1/2 cup at a time. Gently spoon batter into an ungreased 10-in. tube pan. Cut through batter with a knife to remove air pockets. Bake on lowest oven rack at 350 ° for 35-40 minutes or until golden brown and entire top appears dry. Immediately invert pan; cool completely, about 1 hour. Run a knife around side and center tube of pan. Remove cake; split into two horizontal layers. Place cake bottom on an ovenproof plate. Spread with lemon curd; replace cake top. For meringue, in a small bowl, beat egg whites and cream of tartar on medium until soft peaks form. Gradually beat in sugar, 1 tablespoon at a time, on high until stiff glossy peaks form and sugar is dissolved. Spread over top and sides of cake. Bake at 350 ° for 15-18 minutes or until golden brown. Refrigerate leftovers.
