Make an 8 inch layer cake and add icing and swirls on top for the bottle caps.I replaced the water with soda pop in my white cake mix- this is optional, but adds to the theme
You will need several bottle caps
Nik L Nips or similar wax pop bottle candies
1bag each of peanut butter m&m'sregular m&m's and mini m&m's
Position the Nik L Nips on top. I used toothpicks inserted into the wax on the bottom to hold them up- just be sure not to poke through to the liquid.
Stick the bottle caps into the swirls on top and make a "fizzy" look with the m&m's by placing the peanut butter m&m's on the bottom of each fizz column first, then the regular m&m's and the two on top are mni m&m's. Repeat the same pattern all the way around for a uniform look. So easy and fun!
