Gather all your ingredients on the counter to ensure a smooth workflow.
In your blender, combine the unsweetened almond milk (or milk of choice) and the frozen banana (or Greek yogurt). Blend on high until smooth and creamy.
Add the frozen fruit of your choice and blend again until all the fruit is incorporated and the mixture is thick.
Add a handful of spinach or kale to the blender and blend until the greens are fully blended into the smoothie.
Add your nut butter, chia seeds (or flax seeds/hemp hearts), oats, protein powder, and ground cinnamon. Blend until everything is well combined and has a smooth texture. If the smoothie is too thick, add more almond milk until you reach your desired consistency.
Taste your smoothie and if you prefer it sweeter, add a drizzle of maple syrup or honey to taste and blend again.
Pour your smoothie into a glass or jar, top with fresh fruit, a sprinkle of chia seeds or hemp hearts, and a dash of ground cinnamon. Enjoy immediately!
