With the extra thickness I add an extra 10-15 minutes (total of 30-35 min) to the normal recipe bake time but I also use the toothpick (or wooden skewer for the extra depth) test to tell when it is really ready. I also agree with "cowgirl" about preheating if using C.I. or you may experience stickage.
Thanks.Grillin and smokin and cookin veggies I am comfy with,...baking,...not so much.
