Preheat oven to 350°F. Grease and lightly flour a 9 x 5 inch loaf pan.
Sift flours into a mixing bowl. Add sugar, baking powder, salt, bananas, butter, rum molasses and egg. Beat for 3 minutes with an electric mixer set on medium. Stir in raisins.
Pour batter into loaf pan. Bake in preheated 350°F oven, on rack set on middle rung for 55 to 60 minutes or until toothpick comes out clean. Allow to cool in pans for ten minutes on a wire rack. Then invert and remove from pan to finish cooking, also on wire rack.
