Frequently Asked Questions
How many grams is ⅓ cup of creamy peanut butter? ▾
⅓ US Cup of creamy peanut butter measured packed firmly into cup weighs 86 grams (3.03 ounces).
Why is chunky peanut butter slightly lighter per cup than creamy? ▾
Rough peanut pieces cannot pack together as seamlessly as homogeneous puree, leaving small gaps that reduce cup weight by ~8g.
Can natural peanut butter be swapped 1:1 for commercial creamy peanut butter? ▾
Yes by weight, but stir thoroughly to integrate separated oil, and consider cookies may spread slightly more due to lack of hydrogenated palm oil.
