Prepare your ingredients: Start by peeling and slicing your ripe banana. If you prefer a thicker consistency, use a banana that has been frozen for a few hours.
Blend the base: In a high-speed blender, combine the banana, almond milk, maple syrup, and ground cinnamon. Blend on high until the ingredients are smooth and well combined.
Add the chia seeds: Toss in the chia seeds and vanilla extract (if using), and blend again for a few seconds to incorporate them. These seeds will give your smoothie a subtle texture and make it more filling.
Add ice and blend again: Throw in the ice cubes for that refreshing, chilled effect. Blend until smooth and creamy.
Taste test: Give your smoothie a quick taste and adjust the sweetness or cinnamon level to your liking. If you prefer it sweeter, add a bit more maple syrup. Want more spice? Sprinkle in a dash more cinnamon!
Serve immediately: Pour your Cinnamon Maple Smoothie into a tall glass and garnish with a sprinkle of cinnamon on top. You can even add a drizzle of maple syrup for extra flair.
