Put the Greek yogurt and protein powder into a mixing bowl.

Add nut butter and cocoa powder if using.

Stir vigorously with a spoon or whisk until smooth and combined.

If the pudding feels too thick, add a small splash of milk and mix again until you reach the texture you like.

Taste the pudding and stir in honey or maple syrup if you want more sweetness.

Scoop into serving bowls and enjoy right away, or chill in the refrigerator until cold before serving.
