Add the almond milk, cream, xylitol, and cinnamon to a small saucepan over low/medium heat. Bring the pan to a gentle simmer but do not boil. While the milk is heating, add the cocoa powder to your favorite mug.
Step 2
Once the milk is piping hot, add a little to the mug with the cocoa and stir. You want just enough milk to dissolve the powder and create a smooth paste. Add ½ of the remaining milk to the mug and stir well to combine.
Step 3
Taste and adjust sweetener if needed. Add the remaining milk to a blender and blend on a high-speed setting for a minute to froth up. Alternatively, transfer the milk to a well-sealed jar and give it a good shake!
Step 4
Pour the frothy milk into the mug. Cut the marshmallows into small chunks (if using) and scatter over the hot chocolate. Dust with a little cinnamon to serve.
