How to measure tapioca flour

Tapioca flour is light and silky — fluff it with a fork before scooping.

Because a cup measures volume rather than weight, the most reliable way to measure tapioca flour is with a digital kitchen scale. If you are working from cups, keep your technique consistent every time so your results are repeatable. For more, see our guide on baking by weight versus volume.

Substitutes for tapioca flour

1 tbsp tapioca flour = 1 tbsp arrowroot starch (Bob's Red Mill)
Closest functional swap for thickening and gluten-free baking. Arrowroot is less effective as a binder, so in GF baking pair it with other flours.
2 tbsp tapioca flour = 1 tbsp cornstarch (for thickening) (Bob's Red Mill)
Cornstarch thickens roughly twice as strongly, so halve the amount. Best for sauces and pie fillings, not gluten-free flour blends.

Tapioca flour conversions: FAQ

Why doesn't a cup of tapioca flour weigh the same as a cup of water?

A cup measures volume, not weight. Tapioca flour is less dense than water (120 g versus 237 g per cup), so the same volume has a different weight. Weighing in grams is the most accurate way to measure it.
