Recipe scaling
scale ingredients down × 0.55
Area ratio: 64 / 117 sq in
If you scale the recipe
Keep the original temperature and bake time
Area scaling keeps the batter depth similar. Start checking doneness about 5 minutes early.
If you keep the full batch
Split across about 1.83 8x8-inch square pans
One target pan makes the full batch about 1.83× deeper. If using one pan, lower the oven by about 25°F (15°C) and allow extra center-bake time.
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.
