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.
