In a small cup or bowl, stir together the brown sugar and hot water until fully dissolved. This is your quick syrup base. Allow it to cool slightly.
Pour the heavy cream, and milk, into the syrup.
Use a handheld frother, blender, or French press to whip the mixture until it becomes light and creamy. It should still be pourable, don’t overwhip!
Spoon or pour over iced coffee, cold brew, or iced espresso. Sip it as is or use a straw to mix it together and enjoy!
