A purpose-made keto wheat flour blend is the nearest direct substitute for all-purpose flour: one tested blend from King Arthur Baking can replace it one for one by volume or weight. Almond flour (affiliate link) and coconut flour can also make low-carb baked goods, but neither is a cup-for-cup substitute for ordinary flour. The recipe’s structure and liquid matter as much as the flour name.

Quick answer
King Arthur Keto Wheat Flour blend: 1 cup for 1 cup all-purpose flour. This specific tested blend can replace all-purpose flour by volume or weight. It contains wheat and whey, so it is unsuitable for wheat or milk avoidance; follow the maker’s liquid guidance for best texture.

King Arthur Keto Wheat Flour blend
1 cup for 1 cup all-purpose flour. This specific tested blend can replace all-purpose flour by volume or weight. It contains wheat and whey, so it is unsuitable for wheat or milk avoidance; follow the maker’s liquid guidance for best texture.
Almond flour
No universal 1:1 ratio; use an almond-flour recipe. Nut flour has no wheat gluten and makes a tender, rich crumb. Start with a recipe written for it rather than replacing every cup of all-purpose flour in a yeast loaf.
Coconut flour
No 1:1 ratio; use a coconut-flour recipe. It soaks up much more liquid than wheat or almond flour. A tested recipe balances it with liquid and binders; direct substitution is likely to give a dry batter.
How to choose
Use a tested keto wheat blend when you want a familiar muffin or bread method and can eat wheat and dairy. Choose an almond-flour recipe for tender cookies or crusts, and a coconut-flour recipe when you want its flavor and can follow its higher-liquid formula. Check the nutrition label and serving size of any commercial blend.
What to watch for
Do not call every almond- or coconut-flour bake gluten-free without checking the other ingredients and cross-contact. The cited one-for-one claim belongs to a specific keto wheat blend, not to every bag labeled keto flour. Coconut flour especially absorbs far more liquid than wheat flour.
