Preheat the oven to 350°F (175°C). Grease a 9-inch round cake pan.
In the pan, melt the butter over low heat, then stir in the brown sugar and honey until combined.
Arrange banana slices evenly on top of the caramel mixture.
In a mixing bowl, whisk together flour, baking powder, baking soda, and salt.
In another bowl, beat sugar and eggs until light and fluffy.
Add sour cream, vanilla extract, and milk to the egg mixture, mixing until combined.
Gradually fold in the dry ingredients until just combined.
Pour the batter over the bananas in the pan and spread evenly.
Bake for 40-45 minutes or until a toothpick inserted in the center comes out clean.
Let the bread cool for 10 minutes, then carefully invert onto a plate to serve.
