Peel the ripe bananas and break them into chunks. Place them into a blender.
Add the creamy peanut butter, almond milk, honey or maple syrup (if using), vanilla extract, and ground cinnamon into the blender with the bananas.
Incorporate the rolled oats and chia seeds, if desired, for added texture and nutrition.
Blend the mixture on high speed until smooth and creamy, adjusting the thickness by adding more milk or ice cubes as per your preference.
Taste the smoothie and adjust sweetness with more honey or maple syrup if needed.
Once blended to your liking, pour the smoothie into tall glasses.
Notes
Garnish each glass with a sprinkle of ground cinnamon or a slice of banana on the rim. Serve immediately with straws or spoons for a delightful experience!
