About Peanut Butter
Peanut butter is a thick, dense spread used in cookies, sauces and snacks. One US cup weighs about 250 grams because it packs heavily.

How much does a cup of peanut butter weigh?
A standard US cup of peanut butter weighs about 250 grams (8.82 ounces). That makes it about 2.1 times heavier than a cup of all-purpose flour, and heavier than a cup of granulated sugar (200 g). This is why a converter that uses the same factor for every ingredient will give wrong answers: peanut butter has its own density, and recipes depend on it.

Values are reference weights for level, unpacked measures unless the ingredient is normally packed. Brand, moisture, temperature and how firmly you fill the cup can shift the result by a few percent, so for precision baking weigh peanut butter on a kitchen scale and use the cup figure only as a guide. To understand why these numbers differ between ingredients, read our guide on why a cup of flour is not a cup of sugar, or see why weighing beats measuring cups.
