Line a 8x8 pan with foil and lightly grease the foil with butter.
In a saucepan, add the chips, milk, molasses, and butter and set on medium heat.
While the saucepan is heating, go ahead and measure out the spices so they are all ready.
Stir the chip mixture often until all the chips are melted and smooth.
Stir in the vanilla and spices.
Set the prepared pan on a hot pad and pour in the hot mixture. (I also sprinkled with some candy leaf decorations, feel free to decorate as you like or just leave as is after pouring in.)
