In a large mixing bowl, add the Greek yogurt and whey protein powder. Whisk together until smooth, ensuring there are no lumps.

Slowly pour in your choice of milk while continuously stirring. Mix until the ingredients are fully incorporated, resembling a velvety pudding.

Stir in any optional flavorings like vanilla extract, chia seeds, or sea salt for depth. Mix well until evenly distributed.

Ladle the mixture into airtight containers or mason jars, filling them about three-quarters full to allow for expansion.

Cover your containers and place them in the refrigerator to chill for at least 1 hour.
