00 Flour
6.7best for bakingFine Italian flour with similar low protein; produces tender cakes and pasta, nearly interchangeable
Cake flour bakes well because its 7-9% protein content limits gluten development, so chiffon and angel food cakes climb to full volume during the 325-350°F oven set without seizing. A swap that overshoots 11% protein traps the rise as a tough dome and mutes leavening lift. This page ranks substitutes first by protein percentage relative to cake flour, second by starch granule fineness (which governs crumb tenderness), and third by how cleanly each one absorbs the recipe's hydration during creaming.
Fine Italian flour with similar low protein; produces tender cakes and pasta, nearly interchangeable
Swap 1:1 by cup. 00 Flour's 8-9% protein nearly matches cake flour, so chiffon batter rises to within 5% of the same height at 350°F. The finer Italian mill produces a slightly tighter crumb. Skip extra sifting — the grind is already powder-fine.
Gluten-free with fine crumb; best blended with other flours for structure
Swap 1:1 but expect a sandier crumb — rice flour has zero gluten, so the cake leans on egg foam alone for structure and risks collapse if pulled before 200°F internal. Blend 50/50 with another flour for sponge cakes, and add an extra tablespoon of liquid per cup.
Mild sweetness; makes tender crumb but results are slightly more crumbly
Swap 1:1. Oat flour's beta-glucans add tenderness but no gluten, so the cake is more crumbly and holds together for about 2 days before drying. Reduce oven temp to 325°F and add 1 tsp xanthan gum per cup to bind the crumb during the 25-30 minute bake.
Blend 2 tbsp cornstarch with 14 tbsp all-purpose flour to mimic 1 cup cake flour
Blend 2 tbsp cornstarch with 14 tbsp AP flour to mimic 1 cup cake flour. The cornstarch lowers effective protein to 8-9%, and the starch swells at 175°F to lock crumb tenderness. Sift the blend twice — undispersed cornstarch leaves chalky pockets in baked sponges.
Use 1 cup minus 2 tbsp AP flour per cup cake flour; sift twice for lighter texture in delicate cakes
Use 1 cup minus 2 tbsp AP per cup of cake flour, then sift twice for lighter texture. AP's higher 10-12% protein toughens crumb if creamed too long, so cut creaming time to 90 seconds and pull cakes from the oven the moment internal temp hits 205°F.
Higher gluten so use less and add 2 tbsp cornstarch per cup; crumb will be denser
Use 7/8 cup bread flour plus 2 tbsp cornstarch per cup of cake flour. Bread flour's 12-14% protein still produces a denser crumb in cakes — best reserved for muffins or pound cakes where chew is acceptable. Mix only until just combined to avoid overdeveloping gluten.
Slightly sweet and nutty; lighter than whole wheat but denser than cake flour
Swap 1:1 by cup but expect denser crumb — spelt's 11-13% protein and weaker gluten structure produce a rise about 15% lower than cake flour. The slight nuttiness suits carrot or spice cakes more than vanilla génoise. Reduce mixing to 60 seconds after flour goes in.
Gluten-free 1:1 swap with neutral flavor; texture is slightly gummier
Nuttier flavor and denser crumb; best in muffins or quick breads, not delicate cakes
Finer grind works in sponge cakes; yields chewier, denser crumb than cake flour
Blend 2 tbsp arrowroot with 14 tbsp all-purpose flour as a gluten-free cake flour substitute
