Make your espresso or strong coffee either way you prefer. I use the pour over coffee method (I use the Chemex and reusable filter) with finely ground coffee beans. This gives the coffee a super black color and strong flavor. Or you can use your espresso pod machine or whatnot, to yield 2 shots of espresso.

Meanwhile, pour the hazelnut milk into the milk frother. Forth milk following the directions of the machine you choose.

Add sweetener and cardamom to the hot coffee or espresso. Stir with a spoon.

Lastly, pour the frothy foamy milk into the hot coffee. And voila. You have a perfect hazelnut milk latte. You can stir if you'd like to get the flavors well mixed. Serve/drink immediately.
