This caramelized banana upside-down cake is a unique twist on the classic pineapple upside-down cake. The caramelized bananas add a sweet and gooey layer to the bottom of the cake, while the moist and fluffy cake batter balances out the sweetness. To make this cake, you will need ripe bananas, flour, sugar, eggs, butter, baking powder, baking soda, salt, vanilla extract, and brown sugar. Melt the butter and brown sugar in a skillet, then add the sliced bananas and cook until caramelized. Pour the banana mixture into a greased cake pan and pour the cake batter on top. Bake for 30-35 minutes, then invert the cake onto a plate. Serve warm with a dollop of whipped cream or vanilla ice cream.
