Using a little bit of cake flour in this pizza dough creates a crust that's crispy on the outside and deliciously soft and tender texture on the inside. If you can't find cake flour, this is a good substitution: 1. Measure 2 cups (240g) all-purpose flour 2. Replace 4 tablespoons (30g) of the flour with 4 tablespoons (28g) cornstarch. 3. Whisk thoroughly to combine and proceed with the recipe Or, you can just use all all-purpose flour. The crust won't be quite as soft on the inside, but it will still be absolutly delicious!
