Add all ingredients to a glass or jar. Mix until combined.
Refrigerate chia pudding for at least 1 hour. I recommend stirring after 5 minutes to prevent clumps.
Notes
*If your protein powder is not sweet you may need to add sweetener. I prefer to not add sweetener.**Some protein powders are thicker than others so adjust the amount of milk so you can easily stir together the ingredients to form the pudding.
