For the best results, take these steps to make your finished product a work of art:
4. Place a second cake layer, top side up, on top of the frosted layer. Spread a thin coating of frosting on the sides of the cake to sea in any crumbs. Let stand 15 minutes.
5. Add a thicker coating of frosting to sides of the cake. Then frost the sides again, swirling and building up the top edge of the frosting about 1/4 inch above the cake.
6. Let the cake stand -- if time allows -- for about an hour before you slice it to let the frosting set up.
