This adult interpretation switches all of the sugar to brown sugar and cooks the mashed bananas with butter and cognac or dark rum. And it's topped with a slightly boozy glaze.
Similar to banana bread, this moist cake is enriched with creamy buttermilk, brown sugar, butter, walnuts, and rum. Apple juice can be substituted for the rum, and pecans for the walnuts.
I developed this recipe when I was cooking for large groups of people. It's easy to make and gives you plenty of time to do other things while it's baking.
