Add in vanilla extract, honeycomb, and lavender syrup into a tall glass.
Add in a few ice cubes and pour cooled espresso over top.
In a separate mason jar, use an electric frother for a few seconds to froth the milk. (If you don't have a frother, you can add a lid to the mason jar and shake vigorously for about 20 seconds).
Pour the frothed milk over top of the coffee, garnish with a drizzle of honey and lavender flowers (if you wish) and serve immediately.
