In a small saucepan, combine water, sugar and dried lavender buds. Bring to a simmer over medium heat, stirring until the sugar is dissolved.
Remove from heat and let the mixture steep for about 15 minutes.
Strain the syrup through a fine mesh sieve to remove the lavender buds. Let the syrup cool completely.
In a small bowl, whisk the matcha powder with hot water until smooth and frothy.
Use the bamboo whisk or an electric frother for best results.
Fill a glass with ice cubes.
Pour the lavender syrup over the ice.
Add the whisk matcha.
Top with milk, stirring gently to combine.
Garnish with a sprig of lavender (if desired).
Serve immediately and enjoy the calming flavors.
