Can I use cake flour instead of all purpose flower?

Hi Sasha! Thanks for writing in. Because cake flour has a different density and protein content than all-purpose, you'll want to use slightly more of it than the AP flour called for in this recipe. According to the Joy of Baking, that means for every 1 cup of AP flour called for, you'll use 1 cup plus 2 Tablespoons of cake flour. https://www.joyofbaking.com/flour.html

Hope this helps!
