Banana Upside Down Cake

"This Banana Upside Down Cake is a simple, one bowl recipe that’s ready in less than an hour. The caramelized banana and brown sugar topping gives the buttery cake the perfect amount of flavor. And you’ll never guess that this was made from a cake mix, which makes this dessert extra easy! This easy Banana Upside Down Cake starts with a combination of butter and brown sugar to get that ooey-gooey, caramelized topping. I made this entire dish in a cast iron skillet, which results in a high and fluffy cake."
