In a mixing bowl, add Greek yogurt, chocolate protein powder, unsweetened cocoa powder, vanilla extract, and maple syrup. Whisk until smooth for about 2–3 minutes.

Scrape down the sides with a spatula and whisk vigorously for another minute to achieve a creamy texture.

Cover the bowl tightly and chill in the refrigerator for at least 1 hour.

Stir the pudding after chilling. Add a tablespoon of milk or more yogurt if a lighter texture is desired.

Spoon into serving cups and garnish with toppings like whipped cream, shaved chocolate, or fresh berries.
