I baked two chocolate 11" loaf cakes for this Airplane Cake and carved them into the shape of the body of the plane. (I cut each loaf into two layers, sprinkled with cherry brandy and filled with cherry filling). I supported it with a piece of cardboard cut like a rectangle with a triangle on each end.
The wings are made from gum paste with extra tylose added so that they dry really hard. I made the two jet engines and three tail pieces from this gum paste. I covered the body of the plane with rolled fondant, tucking it under the sides of the cake as neatly as possible. I painted on the pattern from the model Air Jamaica plane using paste colours and a makeup wedge and brushes. Vegetable shortening is used in the painting process to make it easier for the colours to spread evenly.
After the body was done, I attached the engines to the underside of the wings and inserted the wings into slots I cut into the side of the body using a sharp pointed knife. The engines are touching the board and help to support the wings. The three tail sections are inserted into the body in a similar fashion.
I used a "Roasting" pan and two boxes store bought cake mixes for the airplane cake. I cooled in the fridge overnight. Decorated the next day.
I carved the airplane shape with a knife adding extra cake to wing tips. Then I iced using two cans store bought whipped chocolate icing and a star tip. For the windshield white icing and outlined in black. Was very simple and cheap for ANYONE to make. And everyone just loved it, they thought it was the coolest cake ever.
But it was really simple, just time consuming. Be prepared for an hour or so of icing. Can be decorated to your liking. Also used blue cotton candy for "clouds".
I also carved the tail wing from additional cake and "glued" on with icing (I used a screwer to hold it up, it started to lean as I was icing). I would also wait till the party to add the cotton candy, It melts pretty quick in a little humidity.
My son really wanted a runway and airplane cake. After looking around for ideas I decided to buy a boxed cake mix and follow the directions to make the 9x13 cake. After letting the cake cool, I tinted several scoops of white icing green with 8 drops of green food coloring. I frosted the outer edges and left and right top borders of the cake with the green frosting. I added green sugar sprinkles to the top edges. Next, I tinted the rest of the white frosting with 5 drops of black food coloring to make the grey for the concrete runway. After spreading the runway I took white icing and piped the runway design. The white borders are done with a thicker tip and the rest with a small round tip. The final addition to the cake was a new airplane we purchased from the Museum of Flight gift shop. We wrapped the landing gear with aluminum foil to keep the plane clean and used a wooden match to tilt the plan like it is taking off. Our son loved his cake, it was relatively easy to make and decorate and he loves playing with his new airplane.
