the batter into each prepared pan. 4. Heat each layer, covered with wax paper, in Microwave Oven 6 1/2 minutes. 5. Allow cake to cool 10 minutes before removing from pan. 6. Invert on cooling rack and remove wax paper from bottom of cake. 7. While cakes are cooling, prepare frosting. In a small mixing bowl, beat egg whites with salt until foamy. Add sugar, 1 tablespoon at a time, beating until stiff peaks form. 8. Pour corn syrup into a 2-cup, heat-resistant, non-metallic measuring cup. 9. Heat corn syrup, uncovered, in Microwave Oven 2 minutes or until corn syrup comes to a boil. 10. Gradually pour boiling mixture over egg whites, beating constantly until frosting is cool and very stiff. Beat in vanilla. 11. Pour rum over the tops of both cake layers. 12. Spread apricot preserves over one of the cooled layers. Then spread some of the frosting on it. 13. Place second layer on top of first layer and spread entire cake with frosting. Tips: Frosting will be neater if you place strips of wax paper under the bottom edges of the cake before frosting the sides. Remember to gently remove wax paper before serving cake. Any leftover frosting can be used on cupcakes or stored in refrigerator for later use.
