In a large bowl, combine ground Nilla wafers, nuts, icing sugar, cinnamon, ginger, nutmeg and cocoa powder. Stir well to combine.
Stir in the bourbon and honey. Add a splash more bourbon if the mix is looking a little dry. You want it moist enough that it holds together when rolled into a ball, without being too soggy.
Roll the mixture into 1" balls.
Melt 1 1/2 cups semi-sweet chocolate chips over a double boiler or in the microwave.
Drop a ball into the chocolate and stir it around with a fork to ensure it is evenly coated. Use the fork to lift out the ball, and then tap the fork lightly against the edge of the chocolate bowl, or a spatula, to help knock off any excess chocolate.
Place the chocolate covered ball on a parchment lined baking tray.
Allow chocolate to set before serving.
