In a small saucepan, whisk together the milk, turmeric, cinnamon, ginger, and black pepper. Place over medium heat and bring to a gentle simmer, whisking often. Do not let it boil.
Once warmed through and spices are dissolved, remove from heat. Stir in honey and coconut oil, if using. Strain to remove the grated ginger, if desired.
Pour into mugs and sprinkle lightly with cinnamon before serving.
