Preheat the oven to 350℉. Grease a bundt pan with cooking spray and dust with flour.
In a large bowl with an electric mixer, beat together the melted butter, brown sugar, and granulated sugar until well combined.
Add the molasses, eggs, and milk, and mix until well combined.
Add the baking soda, baking powder, salt, ginger, cinnamon cloves, and nutmeg, and mix to combine.
Fold in the flour until just combined. Be careful not to over-mix.
Pour the batter into the prepared pan.
Bake in the preheated oven for 50-55 minutes. The top should be golden brown and a toothpick/skewer should come out pretty clean.
Let it cool for 20-30 minutes and then invert to remove the cake from the pan.
Let the cake cool completely before icing.
In a small bowl, mix together the powdered sugar and eggnog. Add milk as needed, for a drizzle-able consistency.
Drizzle the cooled cake with the icing. Enjoy!
