I am going to be making a 12 x 18 sheet cake and then cutting it in half and filling/layering it a 9x12. I have never done this before so I am not sure how many cake mixes it will take ( I add to the mix) and how many servings this will be. Thank you.
It will take 2 cake mixes or 14 cups of batter.
sorry I forgot to add 45 servings.
If you use this chart and it gives you batter amounts:
I apologize for the bad info on the number but the chart is a great reference.
Would I have to use a flower nail in the pan when baking or no?
I do use a flower nail when using a 12x18 pan.
I use 5 nails on the 9 x11 and also the 11 x 15
Bakes more evenly and faster as well
