In a high-speed blender or Nutribullet, combine the frozen banana, frozen acai puree, strawberries, blueberries, soy milk, and maple syrup. Blend until the mixture is smooth, thick, and creamy, scraping down the sides as needed to ensure everything is fully incorporated.

Once blended, pour the vibrant berry mixture into a chilled bowl. Arrange the toppings over the surface, starting with slices of banana and strawberries. Add a sprinkle of blueberries, followed by a dusting of finely shredded coconut, and finish with a handful of chopped walnuts for added crunch and nutty depth.

Serve immediately for a refreshing and nutrient-rich breakfast or snack.
