⭐ All-Purpose Flour with Cornstarch (Best Dairy-Free 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 (about 7-8%) compared to all-purpose flour (10-12%). Cornstarch dilutes the protein in all-purpose flour, reducing gluten formation which is critical for tender scones. This substitution balances structure and tenderness.
To ensure success, thoroughly sift the all-purpose flour and cornstarch together to evenly distribute the cornstarch. Avoid overmixing the dough to prevent toughness.
Compared to original cake flour, scones made with this substitute will be slightly denser but still tender and flaky, maintaining the characteristic crumbly texture.
