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.

Why pan area matters more than volume
When substituting baking pans, base area tells you how ingredient quantity and batter depth relate. Scale the recipe by target area ÷ original area, and the smaller or larger batch should keep a similar depth. If you move the full original batch into a smaller pan instead, the batter gets deeper and needs a different bake plan.
For an area-scaled batch, keep the original temperature and bake time, then start checking about 5 minutes early. If you keep the full batch in a replacement pan with less than 80% of the original area, split it across pans where possible. When one deeper pan is the deliberate choice, lower the temperature by about 10–15 °C (25 °F) and allow extra center-bake time.
Gas marks: a British standard
Gas marks are a scale used in the UK and Ireland. Gas Mark 1 = 140 °C = 275 °F; each additional mark adds roughly 14 °C (25 °F). Most British baking recipes quote Gas Marks alongside °C, but American recipes rarely mention them. Use the converter above any time you see Gas Mark in a recipe.
