Hamburger cake for family reunion picnic. Used 8" bottom and top (left the top rounded) and 10" center. Buttercream frosting all over - center layer I added crumbled chocolate cake pressed into the side of the buttercream. Suggested by another on this site for realistic burger effect and it worked great. Fondant cheese and lettuce. Used real sesame seeds toasted for the top. Was lots of fun to do and a big hit at the party. Thanks for looking.
