In a mixing bowl, combine protein powder, Greek yogurt, and frozen berries. Mix until well combined using a fork, whisk, or blender.

Check the consistency; it should be creamy but thick enough to hold its shape.

Transfer the mixture into small containers or a loaf pan, spreading it evenly.

Cover with lids or plastic wrap and freeze for at least 4-6 hours or until firm.

Once frozen, let it sit at room temperature for a few minutes before scooping and serve.
