Okay, I'll stop teasing. All you need to make cake flour is regular all-purpose flour and cornstarch. That's it! Did you think it would be that easy? I sure didn't. I don't know why I thought it would be so difficult and I don't know why I never thought to figure this out before. Silly me. No more buying extra expensive boxed cake flour anymore! Here's how you do it: for every cup of flour, remove two tablespoons of flour and then replace with two tablespoons of cornstarch. Then sift, sift and sift again. Do this at least three or four times to get it nice, light and fluffy. Ta da - you now have cake flour!
|flour + cornstarch = cake flour!|
|sift and sift and sift|
Now you never have to make an unnecessary late night trip to the store to buy cake flour again!
