-
Use natural peanut butter: This gives your cookies a richer flavor and creamier texture. Avoid brands with added sugars or oils.

Experiment with flavors: Feel free to add spices like cinnamon or nutmeg for extra flavor. You can also try different protein powders for variety.
-
Chill the dough: Refrigerating the cookie dough for about 30 minutes can enhance the texture and make it easier to form into balls.
