Tips for Scaling Recipes
What Doesn't Scale Linearly
Salt, spices, and baking powder should be scaled with more caution — start at 75% of the calculated amount and adjust to taste. Scaling a recipe up dramatically can over-season easily.
Cooking Times
Cooking time does NOT scale linearly. A doubled recipe in the same pan takes longer, but not twice as long. For baking especially, start checking for doneness 10–15% earlier than calculated when scaling up.
Pan Size Matters
When doubling a cake recipe, you need a pan with double the volume (not double the dimensions). Doubling diameter of a round pan increases volume by 4x, not 2x.
