Add frozen banana, milk, almond butter and maca powder to a blender and blend on high until smooth and creamy.
Meanwhile, whisk together the tahini and maple syrup.
Divide the smoothie mixture between two glasses and drizzle in caramel sauce.
Notes
This smoothie is equally delicious without the caramel sauce.The caramel sauce can be made in larger quantities if desired. It is handy to keep a jar in the fridge to drizzle over pancakes, ice cream, waffles etc.
