Peel the banana and slice it into chunks if it is not already frozen. Freezing the banana beforehand helps create a thicker and creamier smoothie texture.

Pour the almond milk into the blender first. Add the frozen banana pieces, almond butter, protein powder, cinnamon, and optional honey. Adding liquid first helps the blender blend frozen ingredients more easily.

Blend the mixture on high speed for about 45–60 seconds until the smoothie becomes completely smooth and creamy. If you prefer a thicker smoothie, add ice cubes and blend again briefly.

Pour the smoothie into a tall glass and serve right away. For presentation, sprinkle a little cinnamon or chopped almonds on top.
