Baking 2 items in same oven

[DebbieD]

Good Evening~ I thought I would ask before experimenting ...... If I am baking 2 - 9x13 pans of Brownies in the same
oven; is the baking time the same or longer? Thank you!

I never bake by the clock, theres too many variable, every oven is different, baking pans are different.
time is just a rough guide, you still have to be able to identify whether its done.
if a knife inserted in the middle comes out with liquid mix on the blade its safe to say its not done.
the top tray will bake first, remove and move the lower one up.

I don't know if anyone else has this problem, but every time I bake two things on different levels in the oven, one tray of muffins is not baked from the top and the other from the bottom, so personally I'm not fan of baking several things at the same time.
