How to measure peanut butter
Creamy and chunky peanut butter weigh about the same per cup. Natural peanut butter separates, so stir the oil back in before you measure, or the top of the jar is runny and the bottom dry. To measure without a sticky cup, pour 1 cup of water into a large measuring cup and add peanut butter until the water reaches 1 1/2 cups: that is 1/2 cup of peanut butter once you pour the water off.
Source: 258 grams per US cup is the cup weight in USDA FoodData Central. A US cup is about 237 milliliters.
