First, gather your sugar-free white chocolate, collagen (if using), sweetener, and a pinch of salt, then place them all into a blender.
Next, gently warm the hemp milk, heavy cream, and vanilla extract in a medium saucepan over medium heat until it starts to lightly bubble around the edges. Don't let it boil vigorously!
Carefully pour the hot milk mixture into your blender with the other ingredients. Blend on high until everything is perfectly combined and frothy.
For ultimate warmth, pour the blended mixture back into the saucepan and briefly re-warm it to your ideal temperature. Finally, divide this comforting drink into two mugs and, if you like, top it with a dollop of lightly sweetened whipped cream for an extra treat!
