Rum and Raisin Banana Cake

Best banana Cake ever, says DH.  I had given up making banana cake as they somehow always seem to taste the same.  This one doesn't.  This is not what it is called in "Country Living" where the inspiration came from.  There it is called, Coffee, Banana and Cardamon Loaf.   I have adapted it to the TMX and made other minor changes.
