2 Cups Coconut Flour in Grams
256 g — that is what 2 cups of coconut flour weighs, spooned and levelled, per King Arthur Baking. It sounds like a small detail, but in baking and in any recipe written in grams, it is the detail that decides whether the result matches the recipe writer's kitchen. Cups are convenient and grams are accurate, and this page bridges the two for coconut flour with a full table, practical examples, and the method notes that make the number trustworthy. Treat every figure here as approximate and check it against a scale when the stakes are high.
Why this number is worth knowing
Coconut Flour shows up in recipes written both ways — cups in American cookbooks, grams in European ones — and translating between them is where most kitchen errors happen. Knowing that 2 cups of coconut flour is about 256 g means you can follow either kind of recipe without converting on the fly, and you can scale a recipe up or down without the rounding errors that creep in when you convert cup by cup. It also means you can compare recipes: if two recipes for the same dish call for very different amounts of coconut flour, the gram weights make the difference obvious in a way cups never do. Keep the table below bookmarked and the conversion becomes second nature.
Coconut Flour cups to grams conversion table
| Cups | Grams | Tablespoons (approx.) |
|---|---|---|
| 1/4 cup | 32 g | 2 g |
| 1/3 cup | 42.7 g | 2.7 g |
| 1/2 cup | 64 g | 4 g |
| 2/3 cup | 85.3 g | 5.3 g |
| 3/4 cup | 96 g | 6 g |
| 1 cup | 128 g | 8 g |
| 1 1/2 cups | 192 g | 12 g |
| 2 cups | 256 g | 16 g |
| 3 cups | 384 g | 24 g |
| 4 cups | 512 g | 32 g |
The tablespoon column is a bonus for recipes that call for a spoonful or two: one tablespoon of coconut flour weighs about 8 g. Remember that a cup is 16 tablespoons, so the numbers in the table are just the cup weight divided by 16, rounded sensibly. 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.
How the weight was measured
Spooned and levelled means the ingredient was measured the way King Arthur Baking measures it: spooned into the measuring cup until heaped, then levelled with a straight edge. Never scoop the cup through the bag or jar, and never tap the cup down, because both pack the ingredient and add weight. The source for the 128 g per cup 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
A bread dough with a hydration target
Bread bakers think in hydration — the weight of water as a percentage of the weight of flour. With 2 cups of coconut flour at 256 g, a 65% hydration dough needs about 166.4 g of water. That calculation is only possible because the flour is weighed; in cups, hydration is guesswork. If your dough feels too stiff or too slack, check the flour weight first before blaming the recipe.
Pancakes on a busy morning
A pancake recipe asking for 1 1/2 cups of coconut flour needs 192 g. Pancakes are quick, and weighing the flour straight into the bowl is actually faster than spooning and levelling three half-cups. The batter stays lump-free because the flour has not been compressed, and the pancakes cook evenly because every batch starts from the same weight.
Halving a muffin recipe
Halving a muffin recipe that uses 1 cup of coconut flour means 1/2 cup, which is 128 g. Half-cup measures are notoriously inaccurate with flour because the small cup packs differently, so weighing 128 g is the reliable way to halve a recipe without the muffins turning out heavy or dry.
How accurate is this conversion?
The figure on this page — 256 g for 2 cups of coconut flour — is approximate, and it is honest to say so. The source value is 128 g per cup, spooned and levelled, from King Arthur Baking, and the confidence in that value is high. Real kitchens vary: the same ingredient from a different brand, a different grind, or a different storage history can weigh a few grams more or less per cup. For everyday cooking that variation does not matter. For baking, where a few grams can change the outcome, it does — which is why the advice on this page is always the same: use the table for planning and converting, and verify with a kitchen scale when the recipe matters. The scale is the only measuring tool that measures what is actually in the bowl.
Baking with coconut flour: the absorption trap
Coconut flour is the most absorbent flour in most kitchens: it can soak up several times its own weight in liquid, which is why recipes built around it use far less flour and far more eggs than wheat-flour recipes. Never swap it cup for cup — a batter made with 256 g of coconut flour where wheat flour was intended will turn into a dry, crumbly brick. If you are adapting a recipe yourself, start with roughly a quarter of the wheat flour by volume, add one extra egg for every quarter cup of coconut flour, and let the batter rest for five to ten minutes before baking so the flour finishes absorbing the liquid. If the batter still looks wet after resting, it is probably right; if it looks dry, add liquid a spoonful at a time.
Frequently asked questions
How many grams is 2 cups of coconut flour?
2 cups of coconut flour weighs approximately 256 g, measured spooned and levelled. The figure comes from the King Arthur Baking value of 128 g per cup. All weights on this page are approximate — verify with a kitchen scale when precision matters.
Does the brand of coconut flour change the weight?
It can, by a few grams per cup. Different brands mill, grind or process coconut flour slightly differently, and moisture content varies with storage. The King Arthur Baking value of 128 g per cup is a standard reference, not a measurement of your specific packet — another reason to verify with a scale for important recipes.
What is the easiest way to weigh 2 cups of coconut flour?
Put your mixing bowl on a digital scale, press tare to zero it, and pour or spoon in coconut flour until the display reads 256 g. Add other dry ingredients on top, taring between each one, and you can measure a whole recipe in one bowl with no extra washing up.
Can I halve or double this amount?
Yes. Half of 2 cups of coconut flour is 128 g, and double is 512 g. Weighing makes scaling exact, whereas halving or doubling cups compounds measuring error. Scale the coconut flour by weight and adjust leavening and seasoning by taste rather than by a straight multiple.
How should I store coconut flour?
Airtight container, cool and dry, up to 1 year. Keeping it sealed and dry also keeps the cup weight close to the 128 g per cup value used on this page.
Can I substitute coconut flour for all-purpose flour cup for cup?
No. Coconut flour absorbs far more liquid than wheat flour, so a direct swap will dry the recipe out. As a starting point, replace each cup of wheat flour with about a quarter cup of coconut flour — approximately 32 g — and add one extra egg plus a little extra liquid. Treat the 32 g figure as approximate and verify with a kitchen scale, then adjust to taste on the next bake.
