Preheat oven to 350F. Grease and flour a bundt or 9" tube pan. Sift together flour, baking powder, and salt. Set aside. Prepare nut mixture: Combine sugar, cinnamon , and nuts in a small bowl. Set aside. Cream butter and sugar; beat until light and fluffy. Add eggs one at a time, beating well after each addition. Stir in sour cream, vanilla, and bananas. Stir in the flour mixture. Pour 1/3 of the cake batter into the prepared baking pan. Sprinkle with 3/4 cup of the nut mixture. Spoon remaining batter over the nut mixture, then sprinkle with remaining nut mixture. Bake in preheated oven for 1 hour, or until toothpick inserted in center come out clean. Cool on a rack for 10 minutes, then remove from pan and continue to cool. For glaze: Mix powdered sugar, vanilla, and milk until smooth, adding more milk if necessary. Drizzle over cooled coffee cake and garnish with additional nuts, if desired.
