This is another cake that I took on a 7 hour drive! Traveled as two cakes - base of 11x15" and top of 6" round. All devils food cake with buttercream frosting. The lettering and candle holders were fondant. The road was graham cracker crumbs. The rocks were thickened buttercream, then coated in sugar. After studying about every tank cake on here, my grandson (it was his 8th birthday) informed me that he wanted a "real" army tank, and I added the helicopter. His 3 1/2 year old sister helped me put all the decorations on the cake. It was an easy, fun cake to make (especially with my little helper!) but shows up as "awfully busy" in the pictures! Thanks for looking!
