Why measuring peanut butter by cup goes wrong
Commercial creamy peanut butter (Skippy, Jif) weighs about 258 grams per cup. Natural peanut butter that separates is closer to 240 g/cup after stirring because it contains less added oil and sugar. The difference matters in peanut butter cookies — natural peanut butter spreads less and leaves a sandier crumb.
Practical tips for working with peanut butter
For peanut butter cookies that hold their shape with a clean ridge pattern, use commercial creamy peanut butter. For sauces and dressings (Thai peanut sauce, salad dressings), natural peanut butter has the better flavor and the better texture once thinned. Refrigerate natural peanut butter after stirring it the first time — it's the only way to keep the oil and solids combined.
Note from this ingredient's record: Creamy, no-stir varieties. Natural peanut butter that separates is closer to 240 g/cup once stirred and can change a cookie's spread.
