An experiment to see how different types of protein powder affect cookies and which works the best
Result: A gritty cookie that was crispy on the outside but spongy inside.
Result: A chewy & gummy cookie with a strong protein powder flavor
Result: Slightly greasy & gritty, but the potential to make a great crispy cookie with a longer bake time
Result: The cakiest and thickest (minimal spread) cookie in these trials, and very dry overall
Result: A soft cookie-dough-like interior but no outside crisp. Best overall flavor of all the trials
Result: An inedible, sticky cookie with zero structure that is impossible to pick up
Result: A very light-colored cookie and extremely gummy with an eggy/salty flavor
Result: Extremely dry and crumbly cookie with a strong Earthy flavor
Which type is best? It depends on the recipe! To learn more about each type of protein and how to adjust your recipes for each, be sure to check out the full post!
I did the same experiment for chocolate cupcakes, so you can see which protein powder worked best in that experiment, too.
