Gluten-Free Flour Blend Calculator

For cookies and bars, a blend of about 50% white rice flour, 25% tapioca starch, and 25% potato starch gives crisp edges with a chewy center. Adding a small amount of almond flour can improve richness. A quarter teaspoon of xanthan gum per cup of flour blend helps bind everything together.

Crumbly gluten-free bread usually means not enough binder or the wrong flour ratio. For bread, use a higher protein base like sorghum or brown rice flour (around 60%), combined with tapioca starch for chew. Xanthan gum is essential — use about ¾ tsp per cup of flour blend. Psyllium husk is another excellent binder that gives bread a more traditional structure.

Not reliably on a 1:1 basis. Even the best gluten-free blends absorb moisture differently, and swapping flours can drastically change the texture of the final bake. Almond flour, for example, is much higher in fat and moisture than rice flour, so substituting it without adjusting liquids will result in a wet, dense product.

Gluten-free flours vary widely in density — a cup of almond flour weighs about 96g while a cup of rice flour can weigh up to 160g depending on how it's scooped. Weighing flour in grams removes this variability and leads to much more consistent baking results, especially important with gluten-free recipes that are less forgiving.

Most blends fail because they use only one or two flours without accounting for protein, starch, and binding needs. A successful blend needs a protein-rich base flour for structure, a starch for lightness and chew, and a binder (xanthan gum or psyllium husk) to replace the role gluten plays in holding the dough together.

Xanthan gum is a common binder used in gluten-free baking to mimic the elasticity that gluten provides. It helps traps gas bubbles during baking, giving rise and structure. For most baked goods, a small amount (¼ to ¾ tsp per cup of flour) is essential. Psyllium husk or flaxseed meal can be used as alternatives.

Yes. Grain-free blends (popular in paleo baking) rely on almond flour, coconut flour, cassava flour, and tapioca starch — none of which come from grains. These blends behave very differently from grain-based GF blends, often requiring more eggs or binding agents to achieve proper structure. They're great for low-carb or paleo diets but need recipe-specific adjustments.

This calculator gives you a starting-point blend optimized for your recipe type. It's based on ratios from established gluten-free baking sources. Results work best as a drop-in substitute for all-purpose flour in gluten-free recipes. For highly specialized recipes (sourdough, choux pastry, etc.), further adjustments to liquid ratios and leavening may still be needed.
