Place the cocoa powder in the blender. Microwave 1 cup of water for 1 minute, then add to the blender and blend on high for 30 seconds.
Add the maple syrup, chia seeds, avocado, vanilla extract, and salt, plus 1 cup of water to the blender and blend on high for 45 seconds.
Slowly stream in the coconut oil with the blender still running. Continue to blend on high until the pudding homogenizes, about 1 minute more.
Transfer to a resealable container and chill in the fridge for at least 2 hours. The pudding will continue to set up as it cools. You can also dose the pudding into individual serving containers then cover and cool.
