I made this over the weekend. It was so good, and moist. The norm would be to bake it in a bundt pan, but I turned them into cupcakes so everyone would have their own without fighting for a slice. I soaked 4 stalks of vanilla beans in the rum for a month before using, it had a very nice familiar smell you would find in Rum and Raisin ice cream. For an added oomph, top it up with some rum flavoured butter icing or rum glaze.
