Add the banana, plant-based milk, yogurt, cocoa powder, maple syrup, and salt to a blender and blend until smooth.
Pour the mixture into a jar or container, then whisk in the chia seeds.
Let the pudding sit for 5-10 minutes, stir once more, and then refrigerate overnight or for at least 6 hours to thicken.
Before serving, top with banana slices, chocolate chips, or your favorite toppings, and enjoy!
