Begin by peeling a ripe banana and placing it into a bowl. Using a fork, mash the banana until it's smooth with minimal lumps, which should take about 1–2 minutes.

Sprinkle in a pinch of cinnamon or nutmeg, and if you'd like an extra touch of sweetness, add a drop of vanilla extract. Mix these ingredients into the mashed banana for about 30 seconds until well combined.

While your banana mixture sits, brew a shot of espresso or a strong cup of coffee. Aim for a strong flavor to balance the sweetness of the banana; this should take about 5 minutes.

In a separate container, heat your choice of milk (dairy or plant-based) until it's steaming but not boiling, about 2 minutes. Use a frother to froth the milk until it's creamy and bubbly.

Pour the frothed milk into the banana-coffee mixture, gently stirring to combine all the flavors. Continue mixing until the ingredients are fully integrated and you have a luscious, creamy texture, which should take about 30 seconds.

Pour your finished Viral Banana Bread Latte into a cozy mug or glass. For a chill version, add ice before serving. Dust the top with a sprinkle of cinnamon for an extra touch.
