Diet Pepsi can cake. I love to make these they are so simple. Cut the top off of a 2L pop bottle place cans of choice pop beer juice around. Use Duct Tape to secure or ribbon. Tape chocolate bars I use the mini bars around as a 2nd level. Stick ribbon to the top (well bottom) of the bottle use tape and or Crazy glue to secure. You can add a balloon or candles.
