Preheat the oven to 350°F (180°C) and line a baking sheet with parchment paper.
In a blender or food processor, combine cottage cheese with egg and vanilla extract. Blend until smooth and creamy.
Transfer blended cottage cheese to a mixing bowl, then add granular sweetener, almond flour, protein powder and a pinch of salt.
Stir until the dry ingredients are fully incorporated and the dough reaches a smooth consistency.Depending on the protein powder choice, you may need to fix the consistency of the dough with a splash of milk if thick, or with more almond flour if sticky. Adjust to your own needs. Fold through chocolate chips.
Scoop out some of dough and shape 9 cookies. Transfer cottage cheese cookies to a parchment paper covered baking sheet, spacing them apart.
Bake cookies in hot oven for 10 to 12 minutes.
Let cottage cheese cookies cool over a wire rack before serving.
