x0.55 multiplier
Recipe scaling
scale ingredients down × 0.55
Area ratio: 64 / 117 sq in
Bake time
Decrease bake time by 10–20%
Depth & temp
Batter will be deeper - reduce oven temp by 10-15 °C (25 °F) and check early.
Multiplier is based on pan area. For recipes measured by volume (cups, mL), multiply each ingredient by ×0.55. Always check doneness with a toothpick - oven variations apply.
