Best gluten-free substitutes for cake flour

Why this works

Wheat does two jobs at once: gluten gives structure, stretch, and chew; the wheat endosperm gives a balanced starch/protein bulk that carries the rest of the recipe. Gluten-free flours split those jobs across several ingredients. Rice flour, sorghum, oat, and buckwheat are the structural and bulk flours but cannot stretch on their own; tapioca, potato, cornstarch, and cassava are the bind-and-stretch starches but go gummy or starchy on their own; almond, hazelnut, chestnut, tigernut, and coconut are fat-and-flavor flours with little or no structure; chickpea, teff, quinoa, amaranth, green banana, masa, and corn flour have strong flavors that pull the recipe in a specific direction. The reliably-clean wheat-to-gluten-free path is therefore a tested commercial 1:1 blend that has already been engineered (rice/sorghum/starch/xanthan in tested proportions) for non-yeasted bakes, a tested gluten-free bread flour for yeast bakes, or a homemade 60-70% structural / 30-40% starch blend with xanthan dosed to the recipe type. Single gluten-free flours work cleanly only as partial replacements (typically 25-30% of the total flour) where the remaining wheat or remaining tested blend still carries the structure.
