I will be making a 14 inch round cake. How much boxed receipe should I make. I've never made one this big before.

I would use 3....my 12 inch takes 2.

A 2" deep 14" round would take 10 cups of batter per layer.

I use two Betty Crocker's for a 14" round. I've read a number of threads that the brand makes a difference.

I'm sure there's a thread somewhere showing how many mixes to use, but here's what I use:

0.5 mix = one 8" round or one 6" square
1.0 mix = one 10" round or one 8" square
1.5 mix = one 12" round or one 10" square
2.0 mix = one 14" round or one 12" square
3.0 mix = one 16" round or one 14" square
