After looking at some of the tank cakes on this site I thought I'd give it a try. Basic 9 x 13 bottom and a bread pan for the top. Used half the cake from the bread pan.
Adding a touch of cocoa to green food coloring can give you the olive green army color. Another neat trick I thought was cool was to get Hershey bars and break them so three sections, stay together that way you can bridge the gap from the top of one Oreo to another without it dropping. I used single pieces to go around the ends of the Oreo and held them on with icing. I left the top side of the bars up to give it a more treadlike feel.
The barrel is a dowel rod with a candle in one end. The camouflage was just melted chocolate chips dribbled on. I did set the cake on a 1 inch wooden base wrapped in tin foil and cut the wood smaller than the cake to give it the appearance of being off the ground. The dirt/sand is a thin layer of icing with crushed graham crackers sprinkled on top.
I actually had to make two of these because we had two parties. So the second one was a snap since I knew what i was doing.
Next cake I am going to attempt a big yellow back-hoe!
My best friend was having her birthday party and the theme was army/camo. I decided to make her a tank cake! I had got the idea for it from this site!
I made a large cake first for the bottom piece and then used a smaller square sized baking pan for the top part. I recommend using chocolate cake, due to the colors of the icing. After they were done, I put the little cake on top of the big cake. We then covered it in brown and green icing in random designs for the camo.
I used Oreos for the wheels and mini sized Hershey bars for the tread. I stuck a cheap inexpensive army man figure toy in the top. And I used a paint brush (the ones that have the black sponge tip - we just tore that sponge tip off) with a thick handle and used a black marker to color it black for the cannon.
Then we stuck little mini sized army man figures around the cake and crushed up inexpensive vanilla cookies to create the "sand". And thus the cake was made! Everybody loved it, not bad for my very first cake!
Oh, and it says "Militia" on the front of the cake, because that was the birthday girl's nickname, which helped spawn the idea of a camo themed party!
I looked at the other cakes made on this website and used ideas I saw here (thanks everyone!). The bottom layer is 9X13 and the top is an 8X8 (cut in proportion to the bottom layer). Inside it was a four layer (cut using dental floss) spice cake with cream cheese frosting but the outside was frosted with Pastry Pride (original flavor-white - not chocolate, although that would have worked). I colored the pastry pride with a lot of brown coloring to get the tan color and used green spray on frosting that I purchased at a party supply shop (but also available at Michaels).
After I frosted the cake brown I sprayed the green on for the camo effect. Then I added Oreos as the wheels and sections of Hershey bars as the track. Finally I used a bread stick for the big gun on the front and used a very thick black frosting I bought at the grocery store.
Finally I added one little army guy and covered him up with brown frosting (to cover the hole he created) and added an Oreo (half an Oreo I was forced to eat the filling and other half) as the hatch before writing my message on the top. It was fun to make.
