⭐ Whole Wheat Flour (Best Vegan Option)
1:1 ratioWhole wheat flour contains more bran and germ than all-purpose flour, which adds fiber and nutrients but can absorb more liquid. This absorption can make brownies denser if not balanced with adequate moisture. However, because whole wheat flour still contains gluten-forming proteins, it provides sufficient structure to maintain the characteristic chewiness of brownies. When substituting, it is important to mix just until combined to avoid overdeveloping gluten, which can toughen the brownies. Additionally, using whole wheat flour can enhance the flavor profile with a subtle nuttiness that complements chocolate well.
