I stacked three sheet cakes. I used a foil cake pan slightly smaller than the cake and cut the center of the top layer out so that the pan would nestle inside it. Put four dowel rods into the bottom layers to support the pan and bottles. I used BC over the edges of the pan and filled the pan with clear gelatin cubes I made using several ice cube trays. I tried to find mini bottles of beer but had to use full size bottles instead.
