The main difference between cake flour and all-purpose flour is the protein content, as we mentioned earlier. All-purpose flour has a higher protein content, which makes it better suited for heavier doughs like bread and pizza crust. Cake flour, on the other hand, is designed for delicate baked goods that need to be tender and soft.
So, if you're making a cake or cupcake recipe that calls for all-purpose flour, you might be wondering if you can just use cake flour instead. The answer is kind of - while you can substitute cake flour for all-purpose flour, you'll need to make some adjustments to the recipe. Think of it like swapping out a sports car for a sedan - they might both get you where you need to go, but they're designed for different purposes.
