Description
- Preheat oven to 350 degrees F (175 degrees C). Spray 3 (8-inch) round cake pans with cooking spray, and line bottoms with parchment.
- Whisk together flour, baking soda, and salt in a large bowl. Whisk together sugar, 2 cups mashed banana, oil, yogurt, buttermilk, vanilla, and eggs in a second bowl until well blended; add to flour mixture and stir just until combined. Divide batter evenly between prepared pans.
- Bake in the preheated oven until a toothpick is inserted and comes out clean, 25 to 30 minutes. Cool in pans on a wire rack for 10 minutes. Remove cakes from pans to a wire rack cool completely, about 1 to1 1/2 hours.
- Meanwhile for the caramel sauce, combine sugar, cream, butter, cinnamon and salt in a small saucepan. Cook over medium heat, whisking constantly, until butter is melted and sugar is dissolved, about 2 minutes. Whisk in 1 1/2 mashed banana, vanilla bean paste, and 3 tablespoons of the rum and remove from heat.

- For the caramel frosting, beat butter in the bowl of a stand mixer fitted with the paddle attachment on medium speed until light in color, about 3 minutes. Gradually add powdered sugar, and beat on medium speed for about 3 minutes until light and fluffy. Add 1 cup of the salted banana caramel sauce, and beat on low speed until combined, about 1 minute. Transfer 1 cup frosting to a piping bag fitted with a #12 tip.
