⭐ Gluten-Free All-Purpose Flour Blend (Best Gluten-Free Option)

1 cup gluten-free flour blend per 1 cup all-purpose flour

Quick tip: May produce a slightly denser doughnut with a different crumb structure; best if blend contains xanthan gum.

Gluten-free flour blends often combine rice flour, potato starch, and tapioca starch to mimic the properties of wheat flour. The inclusion of xanthan gum or guar gum helps provide elasticity and structure that gluten normally offers.

For best results, use a blend specifically formulated for baking and ensure the dough is not overmixed. You may need to add a binding agent if the blend lacks one.

Doughnuts will be denser and may have a slightly different mouthfeel, but still tender and enjoyable for those avoiding gluten.

Oat Flour

Quick tip: Creates a slightly crumbly doughnut with a mild oat flavor; best combined with a binding agent.

Oat flour is gluten-free and low in protein, which means it lacks the structure-building gluten necessary for doughnuts. Adding baking powder helps with leavening, but the texture will be more crumbly and less elastic.

To improve results, combine oat flour with a small amount of vital wheat gluten or xanthan gum if gluten-free is not required. Watch dough hydration carefully as oat flour absorbs moisture differently.

Doughnuts will be tender but crumbly with a distinct oat flavor, differing significantly from traditional doughnuts in texture.
