2 Cups Cake Flour in Grams
2 cups of cake flour weighs 240 g (spooned and levelled, King Arthur Baking). That single number is the whole point of this page, but the reason it matters is that cups measure volume and recipes live or die by weight. Cake Flour is one of those ingredients where a cup can hide a surprisingly wide range of weights, so converting to grams takes the guesswork out. Every figure on this page is approximate and comes from the King Arthur Baking value for cake flour, so when a recipe really matters, verify with a kitchen scale.
Why weighing cake flour beats scooping it
Cake Flour is the kind of ingredient where the cup method quietly fails. A cup is a volume measure, and the weight of a volume depends on how tightly the ingredient is packed, how fine it is, and even how humid the kitchen is. Two people filling the same cup of cake flour can easily end up with weights several grams apart, and in a recipe that calls for 2 cups, that difference doubles. Grams remove the variable entirely: 240 g of cake flour is 240 g of cake flour in any kitchen, on any day, in any hands. That is why professional recipes are written in grams, and why converting your cup measurements is the single cheapest upgrade you can make to your cooking. You do not need expensive equipment — a basic digital scale that reads to the gram costs less than a bag of good flour and pays for itself the first time a cake comes out right.
Cake Flour cups to grams conversion table
| Cups | Grams | Tablespoons (approx.) |
|---|---|---|
| 1/4 cup | 30 g | 1.9 g |
| 1/3 cup | 40 g | 2.5 g |
| 1/2 cup | 60 g | 3.8 g |
| 2/3 cup | 80 g | 5 g |
| 3/4 cup | 90 g | 5.6 g |
| 1 cup | 120 g | 7.5 g |
| 1 1/2 cups | 180 g | 11.2 g |
| 2 cups | 240 g | 15 g |
| 3 cups | 360 g | 22.5 g |
| 4 cups | 480 g | 30 g |
The tablespoon column is a bonus for recipes that call for a spoonful or two: one tablespoon of cake flour weighs about 7.5 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 120 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.
There is a dispute worth knowing about. King Arthur lists 120 g per cup; finely milled cake flour is sometimes quoted at 100 g per cup when sifted, so spoon and level rather than scooping. The practical advice is simple: use the value in the table above, measure the way the table describes, and your results will match the recipes this site is built around. If a recipe you are following was written with a different value, follow that recipe's value instead of ours, because consistency within one recipe matters more than which authoritative number you pick.
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 cake flour at 240 g, a 65% hydration dough needs about 156 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 cake flour needs 180 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 cake flour means 1/2 cup, which is 120 g. Half-cup measures are notoriously inaccurate with flour because the small cup packs differently, so weighing 120 g is the reliable way to halve a recipe without the muffins turning out heavy or dry.
Common mistakes with cake flour
The most common mistake is scooping the cup through the container instead of spooning and levelling. Scooping packs the ingredient and can add 10 to 20 percent extra weight — enough to ruin a bake. The second mistake is using a liquid measuring jug for a dry ingredient, or a dry cup for a liquid: the two are calibrated differently and the meniscus on a jug is hard to read at 2 cups. The third mistake is forgetting to tare the scale, so the weight of the bowl gets counted as ingredient. Put the bowl on the scale, press tare so the display reads zero, and then add the ingredient. Finally, do not trust a cup that has been sitting in a humid kitchen: cake flour absorbs moisture from the air, and a cup weighed on a damp day is heavier than the same cup on a dry day. The scale does not care about humidity — it tells you what is actually there.
Frequently asked questions
How many grams is 2 cups of cake flour?
2 cups of cake flour weighs approximately 240 g, measured spooned and levelled. The figure comes from the King Arthur Baking value of 120 g per cup. All weights on this page are approximate — verify with a kitchen scale when precision matters.
Does the brand of cake flour change the weight?
It can, by a few grams per cup. Different brands mill, grind or process cake flour slightly differently, and moisture content varies with storage. The King Arthur Baking value of 120 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 cake flour?
Put your mixing bowl on a digital scale, press tare to zero it, and pour or spoon in cake flour until the display reads 240 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 cake flour is 120 g, and double is 480 g. Weighing makes scaling exact, whereas halving or doubling cups compounds measuring error. Scale the cake flour by weight and adjust leavening and seasoning by taste rather than by a straight multiple.
How should I store cake flour?
Airtight container, cool and dry, up to 1 year. Keeping it sealed and dry also keeps the cup weight close to the 120 g per cup value used on this page.
