Use this guide to make a cross cake without a special pan and NO CAKE LOSS. Works for 9 x 13 and 11 x 15 pans. Cut the cake in half length-wise. Put Section #1 aside. Then cut the other long piece in half and put Section #2 aside. Cut the remaining piece in half to create Sections #3 and #4. Assemble as shown in placement guide. Hope that makes sense. UPDATE: I was just informed of a much better/easier version of this. Here's a link: http://www.cakecentral.com/cake-photo_585813.html
