Frequently asked questions
How many grams is 1 cup of peanut butter?
1 US cup of peanut butter is 258 g. In an Australian, UK or NZ metric cup (250 ml) it is 269 g. Weighing is more accurate than measuring by volume.
How many grams is half a cup of peanut butter?
Half a US cup of peanut butter is 129 g, and three-quarters of a cup is 194 g.
How do I measure peanut butter accurately?
Weigh it. Put the mixing bowl on a scale, zero it and spoon straight in — no transfer loss and no scraping. If you must use a cup, oil it first.
Is natural peanut butter the same weight as commercial?
Close enough. Natural peanut butter separates and can trap more air when stirred, so a cup may run 5–10 g lighter. Stir it thoroughly before measuring either way.
