How many cups of cake batter for a 14X14X3cake pan?

For a 14x14x3-inch cake pan, you will need approximately 10 to 12 cups of cake batter. This estimation is based on the volume of the pan, which is about 588 cubic inches. Generally, most cake recipes yield around 4 to 6 cups of batter, so you might need to double a standard recipe to fill the pan adequately. Be sure to check for doneness as baking times may vary with larger cakes.
