⏱️ Adjusting baking time

Different pan sizes affect baking time. A larger, shallower pan (9×13") will bake faster than a deeper 8" round. Start checking for doneness 5-10 minutes earlier for shallower pans, and expect 5-10 extra minutes for deeper pans. Always rely on visual cues: golden edges, clean toothpick, or springing back when touched.
