Preheat oven to 325° F. Spray a 9x9-inch square pan with vegetable oil spray. Line bottom with parchment paper and spray again.
In a large bowl, whisk flour, baking soda, baking powder and salt together. Whisk in ginger, cinnamon, nutmeg and cloves.
In a separate large bowl, combine eggs, brown sugar, molasses and butter until well combined. Sift flour-spice mixture into bowl with wet ingredients and stir until just combined. Add boiling water and stir until batter is smooth.
Scrape mixture into prepared pan and bake until center springs back when lightly touched and a knife comes out clean when inserted into center, about 40 minutes. Remove and let cool on a rack for 10-20 minutes.
While cake is baking, mix together cream cheese and marmalade until smooth. Refrigerate until needed.
When cake is cool, invert cake onto a plate and peel off parchment. Spread icing over cake, cut into 16 even squares and serve.
