All-Purpose Flour with Cornstarch (Best Option)
For every 1 cup cake flour, use 1 cup all-purpose flour minus 2 tablespoons, plus 2 tablespoons cornstarchCake flour has a lower protein content (around 7-8%) compared to all-purpose flour (10-12%). Adding cornstarch dilutes the gluten-forming proteins, reducing toughness and mimicking cake flour's softness. Cornstarch also absorbs moisture, helping maintain batter consistency.
To succeed, sift the all-purpose flour and cornstarch together to ensure even distribution. Avoid overmixing the batter to prevent gluten development, which can toughen pancakes.
The final pancakes will be slightly less delicate than those made with pure cake flour but will maintain a tender crumb and good fluffiness, making this the closest practical substitute.
