FAQ
How many ounces is 1 cup of peanut butter?

Why do gram weights for peanut butter vary between recipes?
Volume measurements depend on how the ingredient is packed. Spooned-and-leveled peanut butter weighs less than scooped. Our values use standard baking averages, so brands and techniques may differ by a few percent.
Is it better to measure peanut butter by weight or volume?
Weight. A kitchen scale removes packing errors entirely, which is why professional recipes list grams. Use this table to convert older volume-based recipes.
