Sift together the flour, baking soda and salt; add to the banana mixture, blending well. Stir in the walnuts. Spread into prepared pan. Drop the topping in small dollops onto the banana batter. Bake for 45 to 50 minutes or until the coffee cake is a deep golden brown and a toothpick inserted into the center comes out clean. Cool in the pan for 30 minutes. Invert onto a plate,then invert again so coffee cake is right side up on a serving plate.
