Prep the Ingredients: If not using frozen bananas, peel and slice the bananas. If using frozen, simply measure them out.
Combine Ingredients: In a blender, add the bananas, chunky peanut butter, rolled oats, cacao powder, cacao nibs, honey, and milk.
Blend: Blend until smooth and creamy. If you prefer a thicker smoothie, add a few ice cubes and blend again until desired consistency is reached.
Taste and Adjust: Taste the smoothie and adjust sweetness by adding more honey if desired. Blend again briefly to combine.
Serve: Pour the smoothie into two glasses and enjoy immediately.
