Cake
Flour Substitute
About This Recipe
"I
don't always have cake flour on hand, and I'm betting many others don't either.
I have discovered that this substitute works very, very well. Easy too, and it
uses pantry staples!" 
Ingredients 
 
  - 1
      3/4 cups all-purpose flour 
- 1/4
      cup cornstarch 
Directions
 - To
     make two cups of cake-and-pastry flour (cake flour), combine 1 3/4 cups
     all-purpose flour with 1/4 cup cornstarch;
     proceed with your recipe. 
- The
     easiest way to do this substitution is to put 2 tbsp of cornstarch in the
     bottom of a 1-cup measuring cup, then fill the cup as usual with
     all-purpose flour and level top. Repeat process to get your two cups. 
- If
     you only need 1/2 cup of cake flour, put 1 tbsp cornstarch in bottom of
     1/2 cup measuring cup, then fill and level as above.
