Why Does 1 Cup of Peanut Butter Vary?
The weight of 1 cup depends on how you measure. USDA standard (spooned) = 258g.
Spooned & Leveled
Spoon the ingredient into the measuring cup, then level off with a straight edge. This is the standard method used by USDA FoodData Central.
Reference weightSifted
Sift the ingredient first, then spoon into the cup. Sifting aerates the ingredient, reducing weight by 10-20%.
~10-20% lighterScooped (packed)
Dip the cup directly into the bag and pack. This is the most inaccurate method — can be 20-30% heavier than spooned.
~20-30% heavierAbout Peanut Butter Density
Peanut butter density depends heavily on style. Creamy/smooth: 1 cup = 258g. Natural peanut butter (oil separated): similar weight but harder to measure consistently. Crunchy adds variability. 2 tablespoons peanut butter = ~32g.
Pro tip: For consistent baking results, use a kitchen scale. Weight measurements eliminate the variability of cup measurement entirely. USDA values shown are based on the spooned & leveled method.
