Instructables
For those of you who just want to have their cake and eat it too, here is an easy way to make your own custom molds for cake.

Best enjoyed with a refreshing beverage, milk, coffee, tea or a la mode, what better way to celebrate a special occasion than with a custom cake in any shape or character.

This for those of the Ron Popeil school of baking...set it and forget it...we're just too lazy to decorate our cake. Too much work and skill was needed for something like LinuxH4x0r's Instructables Robot Cake. This project is great for those midnight dorm-room snacks which should be able to be made with your toaster oven or makeshift bootleg autoclave.

Step 1: Now whip it, into shape, shape up, get it straight...

This is how to transform any picture or graphic into a cake mold.

Materials:
You need to rummage through your paper recycling bin to look for a stiff piece of cardboard or a cardboard box that you can flatten out. Use a sharp razor or utility knife to slice the cardboard. Use a pair of scissors for fine tuning. Use a roll of packaging tape. Any other tape will do but this is easiest to work with and can conform to the detail contours nicely. The dispenser makes it easy to cut off a piece of tape to use so you don't have to fumble with the roll to find the end when it sticks back on itself and disappears. You will need a roll of the heavy-duty aluminum foil to form the cake pan.

Print out your favorite graphic of the image or character you want to bring to life. Try to get the image as large as a sheet of standard letter or A4 paper. Cut around the outline of the image. You will want to "include" the areas that bridge thin or weak protruding details such as the gap between the whiskers or legs. You are essentially trying to create a mold that you will cast with cake batter. Trace this to a piece of stiff cardboard. Draw or trace onto the cardboard the rest of the outline of your figure. This is to help place your detail pieces. I put my paper image over the cardboard and poked a pen into the endpoints of the lines or shapes to transfer the image. Use a marker to sketch out the rest of the details. If you have a crease or fold from the box in the cardboard, glue a small piece of cardboard on the other side of the crease to strengthen and help the piece keep flat and not bend under pressure.

Cut strips of cardboard about 2 1/2 inches wide, about the average depth of a cake pan. You can make it bigger if you want a deeper pan. You will want the "grain" or corrugations running parallel with the smaller width of your cardboard strip. This makes it easier to bend around your shape. Attach this to your main cardboard shape to form the walls. You will get the hang of creasing the cardboard and using little strips of tape to follow the outside contours. If the strip for the wall is too short to continue, take another piece of cardboard and about 1 inch from the end, peel away an outer layer and the inside corrugation. Butt up the corrugated part and overlap the flap on the last piece and continue with more taping. This will prevent the bump that occurs if you did not do this. Finish up the end piece in the same manner to get a smooth outside side wall. The walls can flare out a bit or just try to keep them vertical as the sides of the pan.

Take a look at your graphic to see what details you want to "pop" out in 3-D. Since cake batter is not the best medium for holding detail, you need to make these accents as large as you can. From more scrap cardboard, create and cut out the accent details making them 3 layers of cardboard thick. These protoype cakes only had 2 cardboard thickness details. Use tape to apply the details. Press the tape as close as possible and try not to have any sharp corners which will puncture the foil in the next step. Use tape to smooth out anything else.

they're so cute!!

You know, you could even make an OVEN out of cardboard too :D Like the ones they made here

My brother was a scout, I remember them making a solar oven out of cardboard and foil. It was shaped like a parabolic dish which focused the solar rays to the center. I think it could boil water. Or just push it up to the campfire for a reflector oven.
Really clever idea. I'll try this on my next cake... sure beats carving shapes out of multiple cakes... but I also like putting icing on the "extra cake" shavings and eating those too.

Thanks, laziness is the mother of invention. Those custom cake pans usually go for around $15 USD so if you start making your own and of the shapes you need, it pays off. You can work on the entire Star Wars collection or any sea creature like the cool shark you did. You can even make a radioactive dog cake!
Mmmm... radioactivedog cake... I can see it on the shelves in W@lm@rt now!

If not, try a cake in the shape of a giant dogbone. I always wondered what was in a Scooby-Snack.

looks tasty, you could even put some icing on it and use different colors for the details. :D

Interesting Idea. But try and break this up into a few more steps than just two.

Sorry, I thought this was another speed contest and wanted to post if fast. Thanks.
It is, but you have another week and a half.
Awesome! I really like the Instructables Robot cake.
