Can I substitute Protein Powder for flour?
Protein powder does not have the same attributes as flour, so cannot be totally substituted for use in baking. However if you would like to give a protein boost to your baking, you can replace a small amount of flour with protein powder. We would recommend not replacing anymore than 1/3 of the flour content of a recipe. We would also recommend replacing one cup of flour with 1/3 of a cup of protein powder. You may have to experiment to get the best results!
