Yes, in my cousin's original recipe, she called for 1/2 cup cake flour and 3 1/2 cups bread flour. However, we have since extensively re-tested this recipe using only all-purpose flour, and the results were not meaningfully different. Since most of us already have all-purpose flour in the kitchen, we switched to 4 cups/570g AP flour. However, if you'd like to continue using the mix of cake flour and bread flour, you can!
