This year, I made a 3 layer cake instead of a 4 layer cake. I was also REALLLLLLY careful in how I made sure the cakes exited their pans. I sprayed the pans with a lot of pam and then tried coating them in a LOT of either flour or cocoa powder. You can see the difference between the cakes covered in cocoa and the coke covered in flour. I far prefer the appearance of the chocolate cakes coated in cocoa, the flour would be better for a vanilla cake. I also made sure to cool the cakes a good bit before taking them out of the pan and to keep them on COMPLETELY flat surfaces (meaning no dinner plates, etc).
This one is digging back in the archives. The "Sam" in question has a March birthday. Yes, a little late. But, well worth it. This is the (in)famous hostess cupcake cake- but this year it stood!!
I only removed the center of the middle cake, and I had already chosen the sturdiest looking cake as the middle one.
And it stood. And it was good. And we rejoiced.
For the recipe, see here. Multiply the cake recipe by 1.5 to make 3 round cakes. Fill with the vanilla filling, but use frosting or filling in between the layers (I did one of each). Go heavy on the frosting in between layers (for flavor and making sure it stays together).
