I found the idea for this Hamburger Birthday Cake on this website! All I used was frosting and cake. For the top bun I used a glass bowl and let it cook for like 40 minutes.

For the meat, I took a paper towel and squished the frosting down. And, for the fries I had some leftover batter so I put it in a 17x8x1/2 inch pan then cut it up.

To decorate the cake I put the tinted icing in a bag and squirted it out of there. It was heavy, but very good!
