Every time I leave the baking stone in the bottom of the oven while baking a cake, the cake doesn’t come out right.
It either sinks in the middle and/or it crumbles a little. (characteristic of a cold oven)
(I preheated the oven for an hour.) If I leave the stone out, I don’t have any issues.
Do I need to move the baking stone to the middle shelf and put the cake pan on it?
Do I need to turn the oven up 25 or 50 degrees?
