Add the frozen banana, creamy peanut butter, milk, yogurt, maple syrup, and flaxseed meal to your high-speed blender like Vitamix Blender and blend for few seconds until smooth and creamy.
If you prefer your smoothies to be bit thinner, try adding extra almond milk. Pour into a glass, top it with banana slices, nut butter and sprinkle a dash of ground cinnamon. Serve immediately!
