Bake for 45 minutes in 350 degree oven. Check and see if center is firm and is a toothpick inserted in middle comes out clean. If not, cook for about 5 more minutes and repeat test. Some ovens and pans will take up to 60 minutes But don't overbake!
If you'd like to make muffins instead, start with cooking them for about 20 minutes if they are standard-sized (but keep an eye on them after 15 minutes).
