Rice Flour:
Grams to Cups
One cup of rice flour weighs 160 grams — considerably denser than most other flours. Made from finely milled white or brown rice, it is a cornerstone of gluten-free baking and produces a fine, slightly grainy texture.

About Rice Flour
Rice flour's high density (160 g/cup vs. 120 g/cup for all-purpose flour) is important to account for when converting recipes. Using the same cup measure as all-purpose flour means you'll be working with 33% more flour by weight, which can dramatically dry out batters and doughs if not compensated for.
White rice flour has a more neutral flavor and finer texture than brown rice flour, which carries a subtle nuttiness. Both are naturally gluten-free, but white rice flour is generally preferred in delicate baked goods where a clean flavor is important, such as shortbreads, macarons, and rice-based cakes.
Because rice flour lacks gluten, it doesn't develop the elastic network that traps gas and gives structure to baked goods. It's most effective when blended with other gluten-free flours (like tapioca starch or potato starch) or with a small amount of xanthan gum, which mimics gluten's binding properties.
In Asian baking traditions, rice flour has been used for centuries in mochi, rice cakes, and steamed buns. These recipes are specifically designed around rice flour's unique properties — they don't require any gluten substitutes.
Tips for measuring Rice Flour
- Weigh carefully — at 160 g/cup it's much denser than wheat flour.
- Blend with tapioca starch for a lighter texture in gluten-free baking.
- Sift before using to break up any clumps that form during storage.
- Use white rice flour for neutral flavor; brown rice flour adds nuttiness.
Common mistakes
- Swapping rice flour 1:1 by volume for wheat flour — you'll add 33% more by weight.
- Expecting it to behave like wheat flour without a binding agent.
- Using it alone in raised breads — it needs starch blends for structure.
