I am looking to make a baseball shirt cake for my sons 1st birthday. I want to make it a 2 layer cake meaning the same size just so its thicker! What do I need to make the cake stick together? I will not be using a shirt cake pan because I can not find one nor do I have time to order one! Please help me. I also will be using a special cake and frosting recipe that has no sugar. Any help would be great. Thank You so much in advance
