No. Cake flour is simply a finer grind with Floral any woman can be a mother but it takes someone special to be a softball mom shirt slightly lower protein and so a lighter flour and gives less chew in the resulting baked goods. Replacing 2T per cup of regular flour with cornstarch is purported to be an acceptable substitute. Without substitution, you will still have a cake that looks and tastes great.
Just a little denser and perhaps chewier (the protein in Floral any woman can be a mother but it takes someone special to be a softball mom shirt flour is gluten and is what causes binding in baking) than if you had used cake flour. So if you need the lightest, most melt-in-your-mouth cake, then get the cake flour or substitute. But I wouldn’t bother to keep cake flour on hand for most times that I bake.
