All-Purpose Flour (Best Option)
1:1 by weightAll-purpose flour contains about 10-12% protein, lower than bread flourβs 12-14%, which reduces gluten development slightly. This balance is ideal for brownies, as it prevents toughness while maintaining enough structure to hold the dense batter.
When substituting, measure by weight to maintain accuracy. Avoid overmixing to prevent excess gluten formation, which can toughen brownies.
Compared to bread flour, all-purpose flour yields a brownie with a tender crumb and a fudgier texture, which is often preferred in brownie recipes.
