In a bowl, combine Greek yogurt and protein powder. Stir until fully blended.
Add cocoa powder (if using), peanut butter, sweetener of choice, and salt.
Mix well until smooth. If it’s too thick, add a small splash of milk to reach your preferred consistency.
Spoon the pudding into serving dishes or jars.
Pop them in the fridge for at least 30 minutes to chill—or eat it right away if you just can’t wait.
Top with chopped nuts, fruit, or a sprinkle of granola before serving (optional).
