| Cocoa Powder (unsweetened) | 75g |
| Tapioca Flour (Starch) | 90g |
| Cornstarchcurrent | 96g |
| Arrowroot Powder | 96g |

Measuring Cornstarch Accurately
Why weight matters: 3/4 cup of cornstarch can weigh anywhere from 82g to 115g depending on how you measure it. The USDA standard is 96g (spooned and leveled). Scooping directly from the container can add 10–20% extra weight, which affects recipe results — especially in baking.
About cornstarch density: Cornstarch (corn flour in UK) is a fine white powder. 1 cup = 128g. Used as a thickener for sauces and gravies. 1 tablespoon cornstarch = 2 tablespoons all-purpose flour as a thickener.
About 3/4 Cup as a Measurement
3/4 cup = 12 tablespoons = 180ml. This is one of the four standard cup measures (1/4, 1/3, 1/2, 3/4, 1). Common in cookie recipes where the flour amount sits between 1/2 and 1 full cup.
Three-quarter cup is a frequent flour amount in drop cookies, scones, and coffee cake toppings. At 180ml, it is exactly 3/4 of a standard US cup (240ml) and 12 tablespoons precisely.
Frequently Asked Questions
How many grams is 3/4 cup of cornstarch?
3/4 cup of cornstarch weighs 96 grams (3.39 oz, 180ml). Based on USDA FoodData Central: 1 cup cornstarch = 128g, so 3/4 cup = 128 × 0.750 = 96g.
Is 3/4 cup of cornstarch the same weight every time?
The weight can vary slightly depending on measuring technique. Spooned and leveled gives 96g. Scooped (packed) can be 10–20% heavier. Sifted gives a lighter weight. The USDA standard (spooned and leveled) of 96g is the most reliable baseline for recipes.
How do I accurately measure 3/4 cup of cornstarch?
For accuracy, use a kitchen scale and weigh 96g of cornstarch. If using measuring cups, spoon the cornstarch lightly into a 3/4 Cup measuring cup and level off the top with a straight edge. Avoid scooping directly from the container, which compacts the ingredient and adds extra weight.
How does 3/4 cup of cornstarch compare to other ingredients?
3/4 cup of different ingredients varies significantly: Cocoa Powder (unsweetened) = 75g, Tapioca Flour (Starch) = 90g, Cornstarch = 96g. This is because each ingredient has a different density.
