lbs. cake flour
Cake flour is a refined grain product that is a source of carbohydrates and provides iron and B vitamins, typically including added thiamine, riboflavin, niacin, and folic acid through enrichment. It contains minimal protein and fat compared to whole wheat flour.
About
Cake flour is a finely milled wheat flour with a lower protein content (7–9%) and higher starch content compared to all-purpose flour, producing a softer, more delicate crumb structure in baked goods. It is typically bleached and chlorinated during processing to further soften the gluten network and increase its water-absorption capacity, characteristics that distinguish it from unbleached alternatives. The fine, powder-like texture and weakened gluten development allow cakes, pastries, and tender baked goods to rise higher with a more uniform, tender crumb.
Cake flour originated in commercial baking contexts in the early 20th century and has become standard in American and modern baking. It is distinguished from pastry flour (intermediate protein content, ~9%) and bread flour (high protein, 12–14%) by its extreme softness and capacity to suspend sugar and fat without developing toughness.
Culinary Uses
Cake flour is the preferred flour for tender cakes, cupcakes, and delicate pastries where a fine, moist crumb is desired. It is essential for layer cakes, angel food cakes, chiffon cakes, and certain cookie types that require softness rather than structure. The low protein content prevents overdevelopment of gluten, which would create a dense or tough product. Cake flour is also used in some pie doughs and biscuits to achieve tenderness. In professional baking, it is often preferred over all-purpose flour when maximum tenderness and lift are the goal, though it can be partially replicated by substituting a portion of all-purpose flour with cornstarch (approximately 2 tablespoons cornstarch per cup of all-purpose flour).
