How many cake boxes do you need for a 12x3 round pan?

Answer 1

The boxes I checked said one box would make a 13x9, so you will need about 1 1/2 boxes for a 12x18. Assuming the pan is deep enough you could use two boxes for a one layer 12x18 or you may want to make a two layer cake using 1 1/2 box per layer.

Answer 2

A 12x18x2 pan is a half sheet pan takes 14 cups of batter to make a one layer, 2" high cake. That should be about 3 boxes of box cakes. I recommend measuring out 14 cups of batter for the pan and baking any extra batter as cupcakes.

A tip: Bake the cake at 325 degrees F instead of 350 degrees F, so that the corners to not become overdone before the center of the cake is baked through.

Answer 3

You need 3 boxes of cake mix, Make sure you leave at least an inch from the top of the cake pan, so the cake has enough room to raise. Hope this helps!

Answer 4

One box. you just have to use a large bowl
