My husband's friend requested a Storm Trooper cake for his son's party. His wife found a youtube video showing how one mom made it so I thought I'd give it a try. Next month my oldest son is having a Star Wars party so this was going to be good practice. Most of the examples on the internet are made with fondant, which I don't use. Unfortunately, the cake was WAY harder than it looked and didn't turn out that great. However, I thought the technique was pretty cool and could be tweaked to make lots of different of cakes. So, here's how I did it...not my best work, but definitely my best effort.
I made simple syrup for the first time, with equal parts sugar and water that I boiled in a pot. I added a whole lemon to it as well. Then I used buttercream frosting and my Kitchen Aid mixing bowl as a mold.
I lined my Kitchen Aid bowl. Plastic wrap would work but I usually end up annoyed with it so I went with good old wax paper instead.
