Preheat oven to 350°F. Line a baking sheet with parchment paper and set aside.
In a large mixing bowl, combine almond protein powder and brown sugar with water and mix until smooth. Add egg and vanilla extract and mix until well incorporated, then add flour, baking soda and salt and mix until smooth. Fold in chocolate chips. Mixture will be very soft.
Portion onto the prepared baking sheet, about 1 tablespoon per cookie, leaving 1 inch between. With wet hands, slightly flatten each cookie.
Bake until just slightly browned, about 15 minutes. Let cool at least 10 minutes before removing to a wire rack to cool completely. Store in an air-tight container.
