I baked this Homemade Airplane Cake for my son's 6th birthday. I used two large rectangular shaped cakes, which I then cut and layered after following a layout on this site (aiplane cake 08). The cut-out (though a square and mine a rectangle) enabled me to use the entire cake with all the cut outs, so there was absolutely no wastage.
I placed black project cardboard on a 600x600 tile and used masking tape to run down as the runway. On the sides, I colored green coconut as the grass along the runway.
For the windows of the cockpit, I used blue cellophane paper which we cut up and the colored wing decorations were sour sweets. It was a bit more time consuming then the other cakes that I have attempted over the years, but the end result was worth it.
For this airplane cake I used 2 13x9 sheet cakes and a small round bowl cake. I used pound cake because of the crumbs. The body of the plane was made from one sheet cake cut in half longways, stacked, and carved. The wings are made from the other sheet in cake. The nose is made from the bowl and covered in fondant.
The top set of wings is on a cake board cut to shape and is supported by a dowel rod on either side. The whole thing is piped in different shades of buttercream. The accessories were purchased at Michael's craft store. The propeller is a piece of cardboard covered in fondant.
For this homemade 2nd birthday plane cake I cut off an 8 in square yellow cake into segments (like building blocks) and arranged it into an airplane shape. Glue the segments together with some frosting. Put the cake in the fridge for a couple of hours.
Next step was to crumb coat the cake with a thin layer of frosting. Pop it back into the fridge. When you're ready to decorate, take it out from the fridge and ice the cake. I used buttercream. Put in a small teddy biscuit as the pilot, some smarties as the window, and draw some lines to 'shape' the plane.
