For the lightning bolt, I decided it would be easiest to just make a mold, because cutting it out of a rectangle would be a nightmare. To begin I googled harry potter lightning bolt and I decided that this one was the best for a cake. Once I had the image, I drew it onto a large sheet of tin foil. We were originally going to put the tin foil around a card stock lightning bolt base. but then decided better against putting paper in the oven...
The next step is where it gets tricky. To make the walls of the mold you have to fold the tinfoil up around the traced lightning bolt. Because one sheet isn't going to be enough you have to tear off more smaller sheets and continue to add them to the sides and bottom to make a stable mold. You have to be patient for this part. Tin foil doesn't stick to itself like plastic wrap so you need to pinch it together and do a lot of folding over to make it keep its shape. Tin foil also rips very easily so be careful when picking up or bending the mold. If it does rip, just tear off another piece of tin foil and patch the rip or the hole. Continue to add reinforcement to the sides and bottom until it feels sturdy enough not to fall apart when you put in the batter.
When you are satisfied with the mold, grease it and put it on a cookie sheet. Putting it on a cookie sheet will make the mold easier to take in and out of the oven, and if it does fall apart, the batter won't get all over the oven. Use the directions on the back of the box for estimating temperature and baking time.
When the cake is done, you can just tear the mold away from the cake. (I forgot to take photo's of the cake after we iced it. We gave it to our neighbors for their harry potter party).
A week later, my friends and I were bored so we decided to make a pokeball cake. We used the easier method to make this cake because a pokeball is just a circle. For this cake we just used a 9 inch cake pan. For the colors we bought vanilla icing and used food coloring to dye it. (There wasn't a black so we just mixed all the colors to create a brown for the middle stripe)
And finally for my friends birthday i baked a TARDIS cake (she is also a huge doctor who fan). I used a 9x13 rectangular pan and cut out cake to make the light on top. The most difficult part was doing the icing. I put vanilla icing in quart sized ziplock baggies, added the appropriate amount of food coloring, and then cut a small hole in a corner so I could squeeze the icing out in a thin line.
Also, When you pour the batter into the pan, make sure you spread it out evenly!!!! I didn't do that great of a job at spreading the batter, as you can see from the picture on the right :P The TADIS is a little swollen...
