Add sliced apple, maple syrup (or brown sugar), water (or apple juice), and cinnamon to a medium pot
Place pot on medium heat for approximately 5 minutes
Bring down to a simmer, place the lid on top, and let simmer for 8-10 minutes until apples are very soft
Set aside and let cool completely
Once cooled, stir in 1 tsp vanilla extract
Strain the syrup and store in the fridge for up to 3-4 weeks
To serve hot: heat the syrup with your desired milk and add to espresso or coffee
To serve iced: froth the cooled syrup with cold milk to create cold foam and top your iced coffee or espresso
