Preheat the oven to 300 degrees. Grease or butter a loaf pan well and set aside.
Mix dry ingredients in a large bowl. In a measuring cup measure out 2 cups buttermilk(or substitute 1 1/2 tablespoons of vinegar or lemon juice and then fill up the measuring cup up with milk to 2 cups) Mix in molasses and then pour into the dry ingredients. Mix thoroughly.
Once completely mixed, pour into the prepared loaf pan and let stand for 10 minutes. After letting it stand, place in the 300 degree oven for 60 minutes.
Check if the loaf is done with a toothpick in the center and when the loaf is done, remove from the oven, run a knife around the edge if needed, then turn out onto a cooling rack and let cool at least 30 minutes before slicing. We like this best served warm with butter.
