I bake from scratch.
And I need to know how much batter this holds.
It's the general equivalent of 2 recipes.
An idea for you is to fill the pan with water to the mark you want to fill it with batter and pour the water out into a pitcher and you'll know for sure. Then it just depends on how many cups of batter the individual recipes yield. It's approximately a double recipe but several variables apply.
Ok I tried it with a 12 inch 3inch high pan.
But i am not so sure still.
Would that be about 10 1/2 cup batter?
I use the Wilton chart meself.
You'll see the following list on the right of the page
Baking Time and Batter Amounts
The right baking times and batter amounts
are an essential part of learning how
to make a cake. Follow the guides below
for baking wedding cakes or birthday cakes.
Wedding cake - 2" deep pans <<< I use this one for my 3" pans
Wedding cake - 3" deep pans
Party cake - 2" deep pans
Party cake - 3" deep pans
So when you get on the chart-- see the 4th column over-- where it says 'cups batter' it lists 8 cups for a 10-inch. The 3" pan chart also says 8 cups.
