A recipe calls for 1/4 cup peanut butter — how many grams should I weigh out?

1/4 cup × 258 g ≈ 65 g. Weighing is especially helpful for sticky ingredients like peanut butter, since you can place the bowl on the scale and add peanut butter directly without losing any to the measuring cup.

Does natural peanut butter (with separated oil) weigh the same as regular peanut butter per cup?

Roughly, yes — stir the oil back in before measuring, since unmixed natural peanut butter has an inconsistent texture that could throw off a volume measurement. By weight, the total mass doesn't change whether the oil is mixed in or separated.

Peanut Butter: 258 Grams

Peanut butter is dense and sticky, weighing about 258 g per cup — more than flour, sugar, or butter by volume. Because it clings to measuring cups and spoons, leveling it off accurately can be tricky; weighing avoids the guesswork of scraping every last bit of peanut butter out of a measuring cup.
