⭐ Gluten-Free Flour Blend with Tapioca Starch (Best Gluten-Free Option)
1:1 substitution for cake flourGluten-free blends that include tapioca starch help mimic the tenderizing effect of cornstarch by reducing protein concentration and adding chewiness. Tapioca starch improves moisture retention and elasticity in gluten-free baked goods.
Ensure the blend contains a balance of starches and proteins; adding xanthan gum or another binder may be necessary for structure. Monitor baking time closely to avoid dryness.
The resulting brownies will be tender and moist but have a different texture profile—slightly more crumbly and less elastic than wheat-based cake flour brownies.
