FAQ
Why does coconut flour need so much less?
Coconut flour is extremely absorbent — it soaks up 3–4× more liquid than all-purpose flour. Use only ¼ of the original amount and add extra eggs or liquid to compensate.
Is almond flour gluten-free?
Yes, almond flour is naturally gluten-free. It produces moist, dense baked goods and is higher in protein and fat than wheat flour, but lower in carbohydrates — a popular choice for low-carb baking.
Can I replace flour 1:1 with oat flour?
Oat flour can replace all-purpose flour at a 1:1 ratio in many recipes, though baked goods may be denser. It contains beta-glucan fibre and has a mild, slightly sweet flavour. Note that commercial oat flour may be processed in facilities with gluten.
Why use this calculator
Flours vary widely in protein content, fibre, liquid absorption, and density. Swapping all-purpose flour for almond or coconut flour 1:1 produces very different results — especially coconut flour, which absorbs several times more liquid. This calculator accounts for those differences.
How to use this calculator
Enter the weight of flour your recipe calls for, select the original flour type, then choose your substitute. Press Calculate for the adjusted amount and baking tips.
What the result means
The result is the amount of substitute flour needed to approximate the same volume. Ratios differ because flours vary greatly in density and absorption — coconut flour, for example, absorbs far more liquid than wheat flour.
Important limitations
Gluten-free flours behave differently from wheat flour. Some substitutions change the final texture significantly. Always test with a small batch first.
