Add the coconut milk, honey, vanilla extract, ginger, turmeric, and black pepper to your blender first. This prevents the frozen fruit from jamming the blades and ensures the spices blend evenly.
Add the frozen banana chunks and mango on top of the liquid. Start blending on low speed, then increase to high once the mixture begins moving.
Use your blender's tamper to push ingredients toward the blades, stopping to scrape down the sides if needed. Blend until completely smooth and thick like soft-serve ice cream, about 1-2 minutes.
Check the consistency — it should be thick enough to hold a spoon upright. If too thick to blend, add coconut milk 1 tablespoon at a time. If too thin, add more frozen banana or a handful of ice.
Pour into a wide, shallow bowl and smooth the top with the back of a spoon. Work quickly before it starts to melt.
Arrange your favorite toppings in sections or patterns for visual appeal. Serve immediately while cold and thick.
