Into each of three large mugs place 1 T coconut oil, 1 row (3 squares) of the chocolate bar, and cinnamon.
Mix cocoa, milk, and cream in a saucepan; stir well with a whisk.
Add the honey and cook over low heat, stirring constantly, until mixture is smooth.
Heat over low to desired temperature. DO NOT BOIL. We like ours at 140° F. (yes, I check the temp with a thermometer)
Stir in vanilla.
Pour into individual mugs, stir to melt oil and chocolate bar.
