Follow these easy steps to make your Banana Bars with Salted Caramel Frosting:

1. Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan.
2. In a mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.
3. Add the mashed bananas to the butter and sugar mix, stirring until well combined.
4. Add the eggs one at a time, mixing well after each addition, followed by the vanilla extract.
5. In a separate bowl, whisk together the flour and baking soda.
6. Gradually add the dry ingredients to the banana mixture. Stir until just combined and smooth.
7. Pour the batter into the prepared baking pan, spreading it evenly.
8. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
9. Once baked, remove from the oven and let cool in the pan for about 10 minutes; then transfer to a wire rack to cool completely.
10. While the bars are cooling, prepare the salted caramel frosting: In a medium saucepan, melt the butter over medium heat.
11. Stir in the brown sugar and heavy cream, bringing the mixture to a boil while stirring constantly.
12. Once boiling, let it cook for an additional 2 minutes without stirring.
13. Remove from heat and stir in the vanilla extract and sea salt. Allow the caramel to cool slightly.
14. Gradually whisk in the powdered sugar until the frosting is smooth and pourable.
15. Once the banana bars are completely cool, spread the salted caramel frosting evenly over the top.
16. Slice into squares and serve!
