Brew a cup of coffee and let it cool completely (or use chilled coffee).

Add the cooled coffee, frozen banana, almond milk, almond butter, chia seeds, vanilla extract, cocoa powder, and maple syrup (if using) to a blender.

Add the ice cubes to the blender for a thicker, colder smoothie.

Blend on high until smooth and creamy, ensuring all ingredients are fully incorporated.

Taste and adjust sweetness if necessary by adding a bit more maple syrup.

Pour the smoothie into a glass and serve immediately.
