I am going to make the christening dress cake and carve it out of sheet cake... just curious as to what recipe and how many boxes of mix i would use???
How much you need depends on how large of a sheet cake you are making. I would do the white almond sour cream cake, it carves great as well as tastes fantastic! The recipe here makes enough batter for a 12X18 sheet.

I use that recipe all the time with other cakes besides white and add the yolks and it comes out soooooo yummy. I also add a box of pudding. It is one of my faves.
Are you saying you add one box of pudding and the 8 egg yolks to the full recipe? What color is it?
I add one box of pudding per box of cake mix, so 2 puddiing. Instead of separating the eggs I add them whole. Sorry for the confusion. Just because I know what I mean does not mean everybody else does. My best friend keeps telling me that. 
I usually only make half of this recipe at a time. I don't usually need this much cake at once.
