Americans consume more bananas than any other type of fruit. And no wonder. Bananas are aseasonal, prepacked in individual servings with easily removable biodegradable coverings (tear off end, pull skin down) and conveniently capable of being shipped green to ripen in your kitchen.

04Pour batter into prepared pan, bake 35 to 40 minutes, until a cake tester comes out clean. Turn onto a rack and allow to cool completely.
05While the cake is baking, melt the chocolate in a double boiler over hot water. Remove from heat. Add butter in small pieces and allow to cool to room temperature. When cool, beat the chocolate mixture until smooth, stir in the milk and rum and beat until spreading consistency. When cake is cooled, frost the top with chocolate and sprinkle with walnuts.
