The problems we had in designing this cake where numerous, the biggest of which being the lack of an oven. We made do with premade pound cake and some snazzy decorating techniques. If your friend just failed his biology test, try making an Evolution cake to inspire progress. If someone's dog died, you could always consider making them an Skelledog cake. This instructable may be used as a jumping off point for the solving of a wide array of emotional issues.
Step 1: Materials
1) Cake base
2) Icing (Four different colors)
4) Mint Patties for wheels
5) Red Vines for the road barrier
6) Nerds for scattered car bits
7) Foil and Cardboard
Step 2: Cut It Up
Then take your delicious cake and start cutting out the general shape of the finished object. We wanted a destroyed car so we cut it in half, made some slopes for the windshield and finally cut off the bumper. Remember a general shape will work, and don't worry too much about mistakes since there will be lots of frosting later.
Step 3: Frost It Fully and Ice It Well
We decided early on that everything in our cake should be edible, this is why we chose nerds to represent scrap bits and peppermint patties as tires. Think creatively and lots of food will turn out to resemble one thing or another.
