How to Measure Peanut Butter Correctly

For cleaner measuring, lightly coat the measuring cup with oil before adding peanut butter.
Natural peanut butter can separate. Stir it fully before weighing or measuring for consistent results.
86g of peanut butter is about 1/3 cup using Spoon & Level. For consistency, stick to one measuring method across the whole recipe.
Why Cup-to-Grams Accuracy Matters for Peanut Butter
Small cup changes create big weight differences. For peanut butter, 1/3 cup is about 86g, but just 1/4 cup more jumps to 150g.
This is why cup-based recipes can drift: packed, loose, or sifted volume can shift your actual grams. Using grams keeps hydration and texture consistent across batches.
