Preheat the oven to 375 degrees Fahrenheit.
Add 1 cup unsweetened hemp protein powder (or substitute your preferred unsweetened protein powder), 3 tablespoons unsweetened cocoa powder, and 1 teaspoon baking powder to a mixing bowl, then mix well.
Add 1/2 cup smooth almond butter, 1/2 cup maple syrup, 2 teaspoons pure vanilla extract, 2 tablespoons cold water, and 1/4 teaspoon salt to a second mixing bowl, then use a whisk to mix well.
Transfer the dry ingredients to the bowl with the wet ingredients, along with 1/2 cup chopped dark chocolate, then use your hands to combine the ingredients until a thick cookie dough consistency is achieved (I recommend wearing kitchen gloves to make this easy and mess free).
Use your hands to divide the cookie dough into 12 evenly sized balls and place them, evenly spaced, on a sheet pan lined with parchment paper.
Use your hands to flatten the cookie dough balls into circle shapes.
Bake for 14 minutes.
Let the cookies cool off for at least 15 minutes before serving.
