Peanut Butter Grams to Cups — FAQ

How many cups is 100g of Peanut Butter?
100 grams of Peanut Butter is roughly 0.39 cups (just over 1/3 cup). Measuring peanut butter by weight is highly recommended because it easily traps air pockets in a measuring cup.
How many grams is 1 cup of Peanut Butter?
One cup of packed peanut butter weighs 258 grams. This can vary slightly between natural and commercial brands, which is why a kitchen scale is your best friend for baking.
How many grams are in 2 tbsp of peanut butter?
Two tablespoons of peanut butter weigh exactly 32 grams. This is the standard serving size listed on nutritional labels.
Do natural and commercial peanut butters have the same density?
They are very close, but natural peanut butter can vary if the oil has separated. Always stir natural peanut butter thoroughly before measuring to ensure a consistent 258g per cup.
Does chunky peanut butter weigh differently than creamy?
Chunky peanut butter may weigh slightly more or less depending on the size of the peanut pieces and how it settles, but for most recipes, assuming 258g per cup works perfectly for both.
Can I substitute almond butter using the same ratio?
Yes, almond butter (260g/cup) and peanut butter (258g/cup) have nearly identical densities. You can substitute them 1:1 by either weight or volume in almost all recipes.
Why should I stir peanut butter before measuring?
Oil tends to rise to the top of natural peanut butters. If you measure without stirring, you might get a cup of mostly oil or mostly dry peanuts, drastically changing the weight and ruining your recipe's texture.
