In a blender, combine the ripe banana, maple syrup, vanilla extract, cinnamon, nutmeg, and sea salt. Blend until completely smooth.

Pour the milk into a small saucepan and heat over medium heat until steaming hot but not boiling, about 3-4 minutes.

Add the banana mixture to the hot milk and whisk together until well combined and frothy.

Prepare 2 shots of espresso or brew 1/2 cup of strong coffee.

Divide the espresso between two mugs, then pour the banana milk mixture over the espresso.

Use a milk frother or whisk vigorously to create a foamy top. Sprinkle with extra cinnamon and chopped walnuts if desired.

Serve hot and enjoy your banana bread latte while it is warm and freshly made.
