Add the baking chocolate and nut butter to a small saucepan and heat over medium low, stirring constantly, until melted and combined.
Stir in the cocoa, maple syrup and salt. It will get thick but it will thin back out as you continue cooking it. Stir in ½ cup of water and continue to cook and whisk until smooth, about 2-3 minutes.
Add the remaining water and cook, whisking for 3-4 more minutes until steaming and smooth.
Pour into a mug, garnish if desired and enjoy!
Notes
LeftoversThe ingredients tend to separate a bit when stored, so I recommend enjoying it immediately. However, if needed, you can allow the hot chocolate to cool for 30 minutes at room temperature and then store in a jar or airtight container in the refrigerator for up to 1 day.Rewarm in a small saucepan over medium heat, whisking constantly, for 4-5 minutes until heated through.
