Peanut Butter Grams to Cups
One cup of peanut butter weighs 258 grams — denser than water, because it is mostly ground nuts and oil with no trapped air. A scale turns the sticky job of packing peanut butter into a cup into a clean pour.
Peanut butter clings to measuring cups, so weighing is both more accurate and less wasteful. Natural peanut butter (just nuts and salt) and no-stir brands weigh about the same per cup — just stir natural jars well first so you are not measuring a cup of separated oil. One rounded tablespoon is about 16 grams.
