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

1:1 substitution with xanthan gum if not included

Quick tip: Provides a gluten-free option but may alter texture and crumb structure, requiring careful mixing and possibly additional binding agents.

Gluten-free blends typically combine rice flour, potato starch, and tapioca starch to mimic wheat flour properties. Without gluten, the cake relies on binders like xanthan gum to provide structure.

Ensure the blend contains xanthan gum or add 1/4 teaspoon per cup of flour to maintain cake structure. Mix gently and avoid overmixing to prevent a gummy texture.

The vanilla cake will be tender and moist but may have a slightly different crumb and mouthfeel compared to traditional cake flour versions.

Oat Flour with Cornstarch

1 cup oat flour minus 2 tablespoons, plus 2 tablespoons cornstarch

Quick tip: A whole grain alternative that softens texture with cornstarch but imparts a mild oat flavor and denser crumb.

Oat flour is naturally gluten-free and has a higher fiber content, which can make baked goods denser. Adding cornstarch reduces protein and lightens texture, helping to approximate cake flour's tenderness.

Use finely milled oat flour and sift well with cornstarch. The batter may require slight adjustments in liquid due to oat flour's absorbency.

The vanilla cake will be moist and tender but with a noticeable oat flavor and a denser, less airy crumb compared to cake flour.
