Dry roast the flax seeds, pumpkin seeds, and sunflower seeds in a pan until they are aromatic and slightly toasted.

Allow the roasted seeds to cool completely.

Combine the roasted seeds with peanuts, roasted chana, almonds, walnuts, chia seeds, oats, and milk powder in a blender or food processor.

Blend the mixture into a fine powder. Store the protein powder in an airtight container.

Add one scoop of the homemade protein powder to a blender.

Add a banana, dates, coffee powder (optional), and chilled water to the blender.

Blend until smooth and serve immediately.
