How much batter for a 10 by 2 cake pan?

For a 10 by 2-inch cake pan, you typically need about 4 to 5 cups of batter, depending on the specific recipe and desired cake height. This generally corresponds to a standard cake recipe that yields around 9 to 10 cups of batter in total. It's always a good idea to check the specific recipe you're using for precise measurements. Additionally, fill the pan no more than two-thirds full to allow for rising.
