This is not my original idea. I saw something like this one online and I wondered if I could ever make one. It was timely that someone requested a beer cake for her daughter's birthday. I originally thought of making an edible beer bottle but ordering the kit in making the mold takes time. So, I tried making this cake and added a few enhancements (additional beer cans on the base and pretzels), I used heavy cream in making the foam effect on the beer mug.
