Banana Bread Crumb Cake - An excellent banana coffee cake with a crumb topping. My mother used to make this many years ago, but she probably used Bisquick in some way. A simple recipe with outstanding results - and no Bisquick required. TIP: If you happen to have Buttermilk on hand, use that in place of reg. milk. Gives it extra height and tenderness. ~ Houston Foodlovers Book Club... WOW! More than 2,500 pins. That's a lot of coffee cake...
