In the microwave or on the stove, warm milk. It will take about 1.5 minutes in the microwave to warm through.
While the milk mixture is heating, make espresso.
Once milk is warmed, stir in maple syrup and vanilla extract.
If you’d like, froth the milk using a small electric or cup frother. If you don’t have a frother you can also whisk the milk mixture vigorously in a pan. Pour milk mixture into a large mug and top with espresso. Stir gently + enjoy!
