Adjusting Recipes
When changing pan sizes, adjust baking time:
- Larger pan: Reduce time by 5-10 minutes and check early.
- Smaller pan: Increase time by 5-10 minutes. Cover with foil if top browns too fast.
- Doubling a recipe for a larger pan: Increase baking time by about 25%.
How to Measure Your Pan
Measure the inside dimensions from edge to edge, not including the rim. Measure depth from the inside bottom to the top of the rim.
