Pan Conversion Tips
Baking Time Adjustments
Larger pans = thinner batter = shorter baking time. Smaller pans = thicker batter = longer baking time.
Fill Level
Fill pans only 1/2 to 2/3 full to allow for rising. Adjust recipe quantity if needed.
Temperature Adjustments
For thinner layers, reduce temperature by 25°F. For thicker layers, you may need to reduce temperature and increase time.
