Grease well and generously flour the bundt pan. Set aside.
Preheat your oven to 350 degrees F.
In a large mixing bowl, whisk together the dry ingredients ( flour, cocoa, sugar, ginger, cinnamon, soda, baking powder, salt ). Add chocolate chips and stir.
In a large mixing bowl of a stand mixer, beat together molasses, oil, eggs, milk, butter and vanilla. Mix until all combined and smooth.
Pour the wet ingredients over the dry ingredients. Add the boiling water and fold in until all combined.
Pour the batter into prepared pan. Bake 45 to 50 minutes or until the toothpick comes out clean.
Immediately flip the cake onto a cake plate. Place the plate over the bundt and turn out. Be careful! The bundt pan is hot!
For the glaze: melt chocolate and butter in a double boiler. Take off the heat when only few butter bits are left. Whisk smooth. Let cool to room temperature. Sift powdered sugar over the melted chocolate and whisk in. Add molasses and vanilla. Whisk until smooth. Add water to get the glaze to a drizzling consistency. Pour over cooled cake.
