Kick the tires and light the fires to 350 degrees.
Cream your butter and sugar together. Then add in your egg and the molasses, whichever you chose to use.
Whisk your dry ingredients together well in a separate bowl. Slowly blend them into the wet mixture, until just combined. The lowest setting on my mixer does such a great job.
When done, take the cup of hot water and add into the mix, combining until it looks like cake batter now, more liquidy.
Pour into a well greased and floured 9x9 pan, and tap it to get the bubbles out.
Bake at 350 degrees until a knife inserted comes out clean, about 40-50 minutes believe it or not, it takes a long time to bake! But keep an eye on it because everyone's ovens are different. I used my Butter Cream Icing on it which was a perfect sweet foil to the dark molasses flavor.
