Peel the bananas and place them in a tall container or mixing bowl suitable for an immersion blender.
Add the coconut oil, cocoa powder, maple syrup, natural peanut butter, vanilla extract, and salt.
Using an immersion blender, blend everything together until completely smooth and creamy.
For chocolate banana pudding: Transfer the mixture to a covered container and refrigerate for approximately 2 hours, or until chilled and thickened.
For chocolate banana ice cream: Instead of refrigerating, pour the blended mixture directly into an ice cream maker and churn according to the manufacturer's instructions until creamy and frozen.
Serve and enjoy!
