Add tahini (or other nut/seed butter), cacao powder, and maple syrup and blend to combine. Then taste and adjust flavors as needed, adding more tahini for nuttiness, cacao for intense chocolate flavor, or maple syrup (or pitted dates) for sweetness. At this time, you can also add vanilla extract or a pinch of sea salt for more flavor. Mix as needed to combine.
*For a refined-sugar-free magic shell, mix 1 part melted coconut oil with 1 part cacao or cocoa powder and sweeten to taste with maple syrup or other sweetener of choice. Add sea salt or vanilla (optional) to taste.
*Prep time does not include freezing bananas.
*Nutrition information is a rough estimate calculated with lesser amount of maple syrup and no additional toppings (tahini or magic shell).
