First, make the banana bread syrup. Add the sliced banana, brown sugar, vanilla, honey, water, cinnamon, and sea salt to a small saucepan, and stir. Bring the mixture to a boil, stirring frequently, then reduce to a simmer.
Simmer the syrup on low heat, stirring often, for about 8-10 minutes, or until all the sugar is melted and the mixture is slightly reduced.
When done, strain the banana solids from the syrup and let it cool to room temperature before using.
To build your latte, you can use hot or iced coffee or espresso. Pour in your favorite milk, then drizzle the syrup on top and mix.
Enjoy!
