Preheat the oven to 350°F (180°C) and line a baking sheet with parchment paper or a nonstick mat.
Stir the flaxseed meal and plant milk together in a medium-sized mixing bowl. Let it sit for 5 minutes so it can thicken.
Add in the nut butter, cane sugar, and protein powder. Combine everything by stirring, cutting, and mashing the ingredients together.
Scoop out 1.5 tablespoon-sized amounts of the thick and sticky cookie dough. Roll them into balls and place them on the lined cookie sheet 1-2 inches apart.
Flatten the cookie dough balls into 1/2 inch round discs with your hands. Top them with chocolate chips by slightly pressing them in.
Bake the cookies for 9-10 minutes or until you start to see a slight golden tint to them. Let them cool for 15 minutes so they can firm up.
