In a small saucepan, combine 8 cups water, cocoa nibs, cinnamon sticks, cardamom seeds, lavender, and star anise. Bring to a boil over high heat; reduce heat, cover, and simmer over low heat for about 25 minutes.
Stir in milk, sugar, and vanilla extract, stirring until sugar is dissolved, about 1 minute. Remove from heat. Strain mixture through a fine-mesh sieve into a pitcher; discard solids. Serve immediately. Garnish with culinary lavender, if desired.
