How to Measure Peanut Butter Correctly
Peanut butter is dense and sticky, so a packed measuring cup weighs much more than a loosely filled cup.
For cleaner measuring, lightly coat the measuring cup with oil before adding peanut butter.
Natural peanut butter can separate. Stir it fully before weighing or measuring for consistent results.
300g of peanut butter is about the measured cup amount using Spoon & Level. For consistency, stick to one measuring method across the whole recipe.
Why Accurate Peanut Butter Measurement Matters in Baking
A 10g error when measuring peanut butter can change your result by 0.04 cups. That's the difference between a perfectly balanced recipe and one that turns out too dry or too wet.
Adding just 10 extra grams of peanut butter (the weight of about one tablespoon) absorbs extra moisture and can turn a tender result into a dense, dry one. Conversely, using 10g less means your structure may not hold.

Frequently Asked Questions - Peanut Butter Conversions
Using the Spoon & Level method (recommended), 300g of Peanut Butter equals 1⅛ cups. With the Dip & Sweep method, it's 1⅛ cups, and when sifted it measures 1⅛ cups. We recommend weighing ingredients for best results, but if you're using measuring cups, the Spoon & Level method is the most accurate.
Yes, significantly. The same 300g of Peanut Butter can measure anywhere from 1⅛ cups (dip & sweep) to 1⅛ cups (sifted) - that's a 0% difference. This happens because dip & sweep compresses the ingredient, fitting more into each cup, while sifting aerates it. For consistent baking results, always use the same method your recipe specifies.
Use the Spoon & Level method: fluff the Peanut Butter in its container first, then lightly spoon it into your measuring cup until slightly overflowing. Level off the top with the flat edge of a knife. Never scoop directly from the bag - this compresses the ingredient and you'll end up with up to 20% more than intended.
It depends on how you measure. Using the Spoon & Level method, 1 cup of Peanut Butter weighs approximately 258g. With Dip & Sweep, it's heavier at about 305g per cup. Sifted Peanut Butter is lighter - about 219g per cup. This is why professional bakers prefer weighing ingredients in grams.
Not exactly. 1 cup of Peanut Butter weighs approximately 258g. 300g equals about 1⅛ cups - roughly 42g more than 1 cup. For precision in baking, it's worth measuring the exact amount rather than rounding to the nearest cup.
Yes, significantly. When Peanut Butter melts, its density changes. 300g of solid Peanut Butter measures about 1⅛ cups, but when melted it takes up about 1⅓ cups - a 14% difference. Always measure Peanut Butter in the state your recipe specifies for accurate results.
300g of Peanut Butter contains approximately 1764 calories, 60g carbohydrates, 75.3g protein, and 150g fat. Per cup (spoon & level), that's about 1517 calories. Values based on USDA nutritional data.
