Preparation / Directions:
Preheat oven to 350 F. In a 10-inch oven-proof skillet, melt 5 1/2 Tbs of the butter with the brown sugar over very low heat. Meanwhile, in a large mixing bowl, cream the remaining 4 Tbs of butter with the white sugar until light. Add the mashed bananas, eggs, vanilla and rum; stir. Then add the flour, baking soda, salt and spices; beat in sour cream. Arrange the banana slices in a pretty pattern in the skillet with the brown sugar mixture; top with the walnuts. Pout the batter over all and place in the oven for 50 to 60 mins or until a toothpick inserted in the center comes out clean. Turn out immediately onto a plate. Serve with ice cream if you are feeling especially sinful.
