Peanut Butter Measurement FAQ
Everything you need to know about converting peanut butter cups and volumes into accurate gram measurements.
A standard, regular-sized peanut butter cup (such as a classic Reese’s) weighs approximately 42 grams. Miniature versions weigh about 9 grams each, while King Size versions weigh around 84 grams.
One standard US measuring cup of packed peanut butter weighs approximately 250 to 270 grams, depending on the brand, texture (creamy vs. crunchy), and how tightly it is packed into the measuring cup.
Volume measurements (like cups or tablespoons) for peanut butter are highly inconsistent due to air pockets, temperature, and how tightly it is packed. Using a digital kitchen scale to measure in grams ensures precise, repeatable results in baking.
While there may be slight variations of 1 to 3 grams depending on the manufacturer, major brands strictly regulate their portion sizes. A ‘regular’ peanut butter cup will almost always be between 40g and 44g across different brands.
