Things to check>>>>
Calibration of oven
Using dark colored metal baking pans not disposables
Pyrex needs to bake at 25 degrees F lower temp
Is the oven fully preheated
Is the cake on the center rack and the ONLY item in the oven
Did you make sure to use LARGE eggs in the mix….that is the size commercial recipes call for in the US, larger eggs in the batter require longer baking times.
Remember: cooking is an art, baking is a science. It requires accurate measurements, time and temperature
