Add pistachio milk, vanilla extract and maple syrup into either a milk frother or a small saucepan. Stir to combine. If using a frother simply froth on your normal setting. If using a saucepan, simply warm up pistachio milk.
Pour warmed/frothed pistachio milk on top of coffee.
Enjoy!
Notes
Make it iced: to make it iced simply use cold/iced coffee or cold brew coffee, don't heat up or froth your pistachio milk and serve over ice! Easy!
