I have posted before about making a tiered cake for my daughter's first birthday. I am completely committed to this, so please don't suggest changing the plan. I have tried several recipes as test runs for the real one, and everyone likes the flavor of the classic Hershey's Cocoa Box cake best. Other trials included Magnolia bakery recipe, Sky High Cakes book recipe, Smitten Kitchen chocolate birthday cake, etc.
My question is: the Hershey cake is soft and fluffy, which is delicious, but does anyone know if my layers will hold up? I am planning to freeze the cakes before I frost them with boiled flour vanilla frosting, so they should firm up, and the frosting is pretty hearty, so that should hold ok. I am going to use straws as supports. Should I be worried about the texture of the cake being strong enough? Any thoughts, advice or experience would be much appreciated. Thank you!
