Peel the bananas and place them in a blender.
Add the peanut butter, full-fat coconut milk, rolled oats, and chia seeds to the blender.
Blend until smooth and creamy.
Add honey or maple syrup if you prefer a sweeter taste.
If you like your smoothie cold, add a few ice cubes and blend until well combined.
Pour into a glass and enjoy your calorie-dense, nutrient-packed smoothie!
