This is an old bran muffin recipe from 1910. It's truly a bran muffin with more bran than many recipes! Instead of raisins, try adding dates, prunes, figs, blueberries or nuts.
I didn't have any treacle but did have dark agave nectar, so substituted this. I also substituted sultanas for raisins, for the same reason. Resulting muffins had great taste and texture. I'll be making a further batch soon! - 23 Apr 2016
I was excited to try this recipe, since it is hard to find the dark bran recipe, and although I wasn’t blown away, they were not a disappointment. I did make some changes: I substituted the buttermilk with plain yogurt, the white sugar for brown, and shortening for margarine (trying to make them even more healthy). I also opted for blueberries rather than the raisins. I loved how moist they were inside, with a nice crust on top, and they expanded really nicely. I did think that the molasses taste was a little strong for me, and I like molasses, but after serving them at my 2 ½ year old’s play date, both the kids and moms really liked the flavour. I think next time I will half the molasses and put some applesauce in and see how it works. Definitely a great, high-fiber snack for kids and adults alike! - 28 Jan 2010 (Review from Allrecipes US | Canada)
HOLY YUMTASTIC!!!! By far the best bran muffin I've ever had, will need to be buying bran by the truckload now haha. I actually omitted the sugar and oil, and added in a shredded apple to make up for it in terms of moistness. They were fantastically moist and tasty. Will make again and again. - 22 Mar 2011 (Review from Allrecipes US | Canada)
