Place the frozen bananas in the food processor and process/pulse until mostly creamy. You may need to turn off the motor and stir/scrape the sides a few times.
Add cocoa powder and peanut butter to the mixture and process until creamy and well combined. Then add the dark chocolate and pulse a few times to incorporate.
Taste and add more cocoa powder or peanut butter according to your preference.
Serve and enjoy! Store leftovers in the freezer…if there are any! We might or might not have eaten all of ours in one sitting. 🙂
