Brew a single or double shot of espresso. Set aside to let cool. To cool quickly, add a few ice cubes.
Add oat milk to a glass. Add orange blossom water and cinnamon. Froth the milk using a milk frother, at an angle, for about 10-15 seconds, until it is foamed to your liking.
Add ice cubes to the glass of milk, ¾ of the way up. Pour the espresso over the iced milk. Top with a dash of cinnamon if desired. Enjoy!
Notes
*You can brew strong coffee if you don't have an espresso machine.**Use the amount according to how much milk/how creamy you like your coffee. I like it creamy, so I use ⅓ cup.
