1/4 Cup Peanut Butter in Grams
1/4 cup of peanut butter weighs 67.5 g (scooped, King Arthur Baking). Ground peanuts, usually with salt and a little oil. All the figures on this page are approximate conversions based on the King Arthur Baking value of 270 g per cup, so when a recipe really matters, verify with a kitchen scale.
Why a quarter cup is worth weighing
Quarter-cup amounts show up in small batches, test bakes and single servings — exactly the cooks where there is no margin for error. A large batch forgives a heavy hand; a small one does not, because the same absolute mistake is a far larger share of the total. Weighing a quarter cup is the cheapest insurance in the kitchen: one number on a scale, and the recipe comes out the same every time.
Scooped is the method behind the number, and it matters. Peanut Butter is used for sandwiches, cookies, sauces and satay. That range of uses is part of why the conversion comes up so often: the same ingredient appears in everyday cooking and in precise baking, and the two situations demand different levels of accuracy. Grams cut through all of that: 67.5 g of peanut butter is 67.5 g whatever the brand, the humidity or the size of your measuring cup.

The tablespoon column shows how many tablespoons each amount equals: a quarter cup is 4 tablespoons, and one tablespoon of peanut butter weighs about 16.9 g. A cup is 16 tablespoons, so the numbers in the table are just the cup weight divided by 16, rounded to one decimal place. For small amounts a scale that reads to the gram is far more reliable than a spoon, because a heaped tablespoon can weigh half as much again as a level one. Read the table from the 1/4-cup row outwards: every row is the cup weight times the fraction, so scaling a recipe up or down is simple multiplication.
How the weight was measured
Scooped means the ingredient is measured the way King Arthur Baking measures it: scooped. For peanut butter, that gives 270 g per cup, and a quarter of that is 67.5 g. The source for the figure is King Arthur Baking, and the confidence in the value is high. King Arthur Baking publishes a standard ingredient weight chart that recipe developers use as a reference, and this page follows it exactly rather than averaging across sources, because an average of two different measuring methods is a number that matches nobody's cup.
Worked examples
Peanut butter cookies, a small batch
A small batch of a dozen peanut butter cookies uses 1/4 cup of peanut butter — 67.5 g — creamed with sugar and egg. The cookies are the classic use for peanut butter in baking, and the weighed amount matters because peanut butter is dense and sticky: a heaped quarter cup is easily 90 g, and the extra fat makes the cookies spread into thin, greasy discs. Weigh 67.5 g, use smooth peanut butter for an even crumb, and chill the dough for twenty minutes before baking.
A satay sauce for two
A satay sauce for two people uses 1/4 cup of peanut butter, 67.5 g, whisked with soy sauce, lime juice, chilli and a little hot water. The sauce should coat a spoon and pour in a ribbon — too thick and it clumps on the noodles, too thin and it runs off. Weigh the peanut butter, add the water a spoonful at a time, and taste for salt and heat before serving.
Overnight oats for one
A single jar of overnight oats uses 1/4 cup of peanut butter — 67.5 g — stirred through the oats, milk and honey the night before. That is a generous amount for one jar, and it makes the oats rich and filling, which is the point on a busy morning. Weigh it, stir it well so there are no streaks of plain oats, and top the jar with sliced banana in the morning.
When a quarter cup matters
This conversion matters most when the recipe is small, the ingredient is potent, or the batch is a test. A quarter cup of a strong flavour or a powerful leavener can make or break a dish, and a test batch is only useful if it tells the truth about the full recipe. Weighing the quarter cup makes the test honest and the small batch repeatable.
Peanut butter is measured scooped, not spooned and levelled, because it is a paste: you scoop it into the cup and level it with a knife, pressing out the air pockets. A quarter cup — 67.5 g — is a substantial amount, and it is easy to over-measure because peanut butter clings to the spoon and the cup. Weigh it straight into the bowl on the scale, and stir natural peanut butter well first, because the oil separates and the top of the jar is runnier than the bottom.
Scaling a quarter cup up and down
The quarter-cup figure is a building block: every other amount is a simple multiple of it. Doubling a recipe that calls for 1/4 cup means weighing 135 g; halving it means 33.8 g, which is 2 tablespoons. A full cup is 270 g, and two cups is 540 g. Writing the recipe in grams at this point is worth doing: the next time you make it, you weigh 67.5 g straight into the bowl and skip the measuring cup altogether. If you are scaling a recipe for a different tin size, convert every ingredient to grams first and then multiply — scaling by volume compounds the error on every ingredient at once, while scaling by weight keeps each one exact.
Common mistakes with peanut butter
- Scooping peanut butter into a cup without pressing out the air. Air pockets make the cup measure light, so you add more to fill it and end up with too much. Weigh 67.5 g straight into the bowl.
- Using natural peanut butter without stirring it. The oil sits on top, so a spoonful from the top is mostly oil and a spoonful from the bottom is dry and stiff. Stir the jar well before you weigh.
- Leaving air pockets in the cup. A paste scooped loosely into a cup carries air, so the cup weighs light and you add more to fill it. Press it in firmly and level it off.
- Scraping the spoon clean into the bowl. The paste left on the spoon is part of the measure — weigh it straight into the bowl on the scale instead.
Storage and handling
Cool cupboard; stir natural peanut butter before use. Keeping peanut butter stored properly also keeps its weight per cup stable: an ingredient that has absorbed moisture from the air weighs more per cup than a dry one, so a sealed container is not just about freshness, it is about measurement accuracy too. If a bag or jar has been open for months in a humid kitchen, the first thing to do before a precise bake is to weigh the ingredient rather than trusting the cup. Label the container with the conversion — 1/4 cup is 67.5 g — and the next person to cook with it will thank you.
Frequently asked questions
How many grams is 1/4 cup of peanut butter?
1/4 cup of peanut butter weighs 67.5 g, measured scooped according to King Arthur Baking. That is one quarter of the full-cup weight of 270 g, and it is the figure to use when converting a recipe from cups to grams. All the figures on this page are approximate, so when a recipe really matters, verify with a kitchen scale.
How many tablespoons is 1/4 cup of peanut butter?
There are 4 tablespoons in a quarter cup, whatever the ingredient. One tablespoon of peanut butter weighs about 16.9 g, so 4 tablespoons come to about 67.5 g. For small amounts like this, a scale that reads to the gram is more reliable than spoons, because a heaped tablespoon can weigh half as much again as a level one.
How do I measure 1/4 cup of peanut butter without a scale?
Peanut Butter is measured scooped, according to King Arthur Baking. Scoop it into a 1/4-cup measure, press out any air pockets, level the top with the back of a knife, and you will be close to 67.5 g. That is the best you can do without a scale — but be honest with yourself that it is an estimate. A basic digital kitchen scale costs less than a bag of good flour and removes the guesswork from every recipe, not just this one.
What is peanut butter used for?
Sandwiches, cookies, sauces and satay. Ground peanuts, usually with salt and a little oil. A quarter cup — 67.5 g — is a common amount in small batches, sauces, dressings and test bakes, which is why this conversion comes up so often.
Is 1/4 cup of peanut butter the same as 4 tablespoons?
Yes, by volume — a quarter cup is always 4 tablespoons. By weight, 4 tablespoons of peanut butter come to about 67.5 g, since one tablespoon weighs about 16.9 g. Tablespoons are sticky and hard to level, so a scale is more reliable for peanut butter than for almost any other ingredient.
Can I use crunchy peanut butter instead of smooth?
Yes, at the same weight — 67.5 g either way. Crunchy peanut butter adds texture to cookies and sauces, which suits some recipes and not others. For a smooth satay sauce, use smooth; for cookies, either works.
