In a small pot, add bone broth, milk, cacao powder, cinnamon, nutmeg, ginger, and a pinch of salt. Whisk to combine. Simmer over low-medium heat for 3–5 minutes, stirring occasionally, until warm. Remove from heat. Pour into a large glass or jar and add collagen powder and raw honey. Froth with a frother and pour into a large mug. Enjoy!
