Whey Protein Powder Substitutes for Flour: Complete Guide

Discover the best whey protein powder substitutes for flour in baking. Learn which alternatives work best for high-protein, low-carb baking recipes.

Quick Answer

Whey protein powder can partially replace flour in baking, but it's not a direct 1:1 substitute. Use plant-based protein powder (1:1 ratio) or combine protein powder with almond flour (1/4 cup almond flour + 1/2 scoop protein per scoop whey). Start with replacing 25-30% of flour.
