Brew a shot of espresso using your espresso machine or coffee maker.
In a separate container, froth the almond milk using a milk frother or frothing wand until it becomes creamy and velvety in texture.
Fill a cocktail shaker or a tightly sealed container halfway with ice cubes.
Pour the freshly brewed espresso over the ice in the shaker.
Add the frothed almond milk to the shaker, ensuring it covers the ice and espresso.
Ensure the shaker is tightly closed, then vigorously shake for approximately 20 seconds to thoroughly blend the ingredients and chill the beverage.
Once shaken, strain the mixture into a glass, discarding the ice cubes.
Add sweetener to taste, if desired.
Serve the shaken almond milk espresso immediately and enjoy!
