Excuse my stupidity...but what is the difference between cake flour and all purpose?
Today I was a cookie baking maniac as I am in charge of cookies for the whole family on Christmas Day. As I got to my last recipe I was 1/4 cup short of flour. Not wanting to go to the store, I substituted cake flour for the last 1/4 cup. I have made these cookies before and they seem to be turning out fine, but I wanted to know the difference between the 2 flours (for future shortages )
