Directions said to cook on 325 for 30 minutes. Using 9 x 13 pan
Are you channeling your best self with this comment? (If you're not sure, check out our Code of Conduct.)
Loosely place foil over the top to keep it from over-browning. And keep baking. :) If the temp was any higher I might say decrease the temp too, but 325 is already pretty low.
perhaps test/calobrate your oven to ensure it is baking at the correct temperature. How un-cooked is the center? Is it still like batter or just a little gooey. I'm assuming you are using the tooth-pick method of checking done-ness. I would concure with the above suggestion: loosley covering with foil and continue to bake until done.
Agree with using loose foil and lowering temperature. I would probably lower it to 300 degrees and if u see top is already quite brown u can try to turn off oven but leave the cake inside and check at ie 5 minute intervals. It has worked for me!
Don't fear for your digits.
