Best Flour for High-Protein Cookies
For high-protein cookies, use a flour that swaps 1:1 so your recipe still works. Fit Flour Original has the most protein of the 1:1 flours we compared: 18g per 1/4 cup. Elevate, King Arthur Keto and Nature's Path Keto also swap 1:1 with fewer net carbs but less protein; almond and coconut flour change the texture and need recipe changes, according to Bob's Red Mill.

Questions
What flour has the most protein for cookies?
Of the flours sold as a 1:1 swap for all-purpose flour, Fit Flour Original (18g per 1/4 cup), then Nature's Path Keto (15g), Elevate (13g) and King Arthur Keto (12g). Vital wheat gluten and protein powders have more, but they replace only part of the flour.
Can I use protein powder instead of flour in cookies?
Not all of it. PEScience, which sells a protein "flour" made of milk proteins, says on its label to "start by replacing 1/4th of the flour in your recipe." A 1:1 protein flour lets you swap all of it.
What is the lowest-carb flour for cookies?
Of the 1:1 flours we compared, Elevate (0g net carbs per 1/4 cup), then King Arthur Keto (4g), Nature's Path Keto (5g) and Fit Flour Original (8g).
