I also found this recipe in a magazine long ago and kept it. I'm glad to see it here! I do double the spices, and typically use only 3/4 cup molasses. This recipe is delicious and beautiful to look at! I serve it with vanilla whipped cream. And I would recommend putting a sheet pan under it in the oven. It makes a very full pan!
I originally saw this recipe in a magazine years ago, and I make it all the time! Big favorite in my family. If you don't have a cast-iron skillet or don't fancy scraping cake bits off yours, a nonstick frying pan works beautifully. Just cover any plastic or otherwise non-ovenproof handle with a couple thicknesses of tinfoil to protect it in the oven.
