How to measure peanut butter

Peanut butter is dense and sticky — press it firmly into the cup to remove air pockets.

Because a cup measures volume rather than weight, the most reliable way to measure peanut butter is with a digital kitchen scale. If you are working from cups, keep your technique consistent every time so your results are repeatable. For more, see our guide on baking by weight versus volume.

Substitutes for peanut butter

1:1 almond butter or cashew butter (The Nessy Kitchen)
Use natural or no-stir-style for the closest consistency. The flavor is milder and slightly sweeter than peanut butter.
1:1 sunflower seed butter (nut-free) (Cotter Crunch)
Best peanut-free option for schools and allergen-sensitive baking. Baking soda can react with chlorogenic acid in sunflower butter and turn cookies/muffins green — harmless but cosmetic.

Peanut butter conversions: FAQ

Why doesn't a cup of peanut butter weigh the same as a cup of water?

A cup measures volume, not weight. Peanut butter is denser than water (258 g versus 237 g per cup), so the same volume has a different weight. Weighing in grams is the most accurate way to measure it.
