All-Purpose Flour with Vital Wheat Gluten (Best Option)
For every 1 cup bread flour, use 1 cup all-purpose flour plus 1 tablespoon vital wheat glutenBread flour typically contains 12-14% protein, which contributes to gluten formation and the chewy texture of sugar cookies. All-purpose flour has about 10-11% protein, so adding vital wheat gluten (pure gluten protein) raises the protein content to approximate bread flour. This ensures the dough develops enough gluten to hold shape and provide the desired chew.
To succeed, mix the vital wheat gluten thoroughly with the all-purpose flour before combining with wet ingredients. Avoid overmixing the dough to prevent toughness. Monitor dough consistency as it may be slightly less elastic than with bread flour.
The final cookies will closely resemble those made with bread flour in texture and structure, with a slight difference in crumb but no significant impact on flavor or spread.
