Peel and slice the ripe bananas.

Add bananas, peanut butter, cocoa powder, milk, honey (or maple syrup), and vanilla extract to a blender. Blend all the ingredients together until smooth and creamy. If needed, scrape down the sides of the blender and blend again to ensure everything is well combined.

Adjust the Consistency: If the smoothie is too thick, add a little more milk. If it's too thin, blend in a few ice cubes or another banana slice to thicken.

Serve: Pour the chocolate peanut butter banana smoothie into a glass or to-go cup.
