Cake flour is softer and lower in protein than plain flour (around 7 to 9% vs 10 to 12%), giving a more tender crumb. It is lighter per cup (120 g vs 125 g); for a quick stand-in when out of cake flour, sift 1 cup of plain flour with 2 tablespoons removed and replaced with cornstarch. See our Cake Flour converter.

Bread flour carries more protein than plain flour (around 12 to 14% vs 10 to 12%), giving stronger gluten and a chewier crumb in yeasted bakes. It is slightly heavier per cup (130 g vs 125 g); swap by weight in pizza, sandwich loaves, and bagels for a more open, chewy texture. See our Bread Flour converter.
