I recently made this cake for my twin boys birthday who love the Avengers! I wanted it to be simple. So, I decided to make Captain America's shield on top. I then followed the Avengers theme on the sides of the cake, by making their symbols all around. I added a few of the Justice league symbols as well because we could not do without the Green Lantern, Superman and the Flash. Of course you can make any symbols you want. I once again used ready made fondant and added food coloring to make the colors I wanted. For the cake itself, you can use your favorite recipe or even a boxed cake. I went with a chocolate cake with a chocolate whipped filling. The boys loved it!
