How do I triple a recipe which uses 9 Inch pan?
They sunk on me, and I did not open the oven. I set the timer for the maximum time on the recipe, and figured I could look in at that time, and extend the time. Then I could use a cake tester.
Could the problem be that I didn't increase the temperature?
Could it be that the aluminum pans expanded, whereas a regular square pan would not do that?
I was in the other room and I heard a sound, like a pan expanding and nobody opened the oven!
Poured equal amount of batter in each pan and baked side by side on middle shelf of the oven.
