Cake Flour: Complete Baking Guide
Ultra-fine for tender, pillowy cakes
What Cake Flour Does in Baking
Cake flour has the lowest protein content of any wheat flour (7–9%), which means it develops very little gluten. The result is an extremely tender, fine-crumbed, moist cake. It's bleached to be very fine, which helps it absorb fat easily — making it ideal for butter-heavy layer cakes and cupcakes.
Key Properties

- ▸Very finely milled — produces a silky, smooth batter
- ▸Bleached to boost starch gelatinization for a softer crumb
- ▸Absorbs more liquid and fat than all-purpose flour

Expert Baking Tips
- 1Sift cake flour before measuring — it clumps easily due to its fine texture.
- 2DIY substitute: remove 2 tbsp from every cup of all-purpose flour and replace with 2 tbsp cornstarch.
- 3Use cake flour for red velvet cake, chiffon cake, and delicate layer cakes.
- 4Cake flour produces a better result in high-ratio cakes (more sugar than flour by weight).
⚠️ Common Mistakes to Avoid
- ✗Using cake flour for bread or pizza — the low protein means almost no gluten, producing a crumbly, flat result.
- ✗Packing cake flour into the measuring cup — always spoon and level.
- ✗Skipping the sift — unsifted cake flour often has small lumps that don't mix out easily.
