Ingredients
Scale
- 2 1/4 cups all-purpose flour
- 1/4 cup cornstarch
- 1 tsp baking powder
- 1 tsp baking soda
- 1/2 tsp salt
- 2 tsp ground cinnamon
- 3 1/2 large ripe bananas, mashed
- 1/2 cup unsalted butter, room temperature
- 1/2 cup vegetable oil (canola preferred)
- 1 1/2 cups granulated sugar
- 3 large eggs, room temperature
- 1 1/2 tsp vanilla extract
- 1/2 cup Greek yogurt, room temperature
- 1 cup chopped walnuts
- 1/2 cup granulated sugar (for caramel)
- 2 tbsp water (for caramel)
- 1/4 cup heavy cream, room temperature (min 34% fat)
- 2 tbsp unsalted butter, cold (for caramel)
- Pinch of salt (for caramel)
- 8 oz cream cheese, softened (for frosting)
- 1/2 cup unsalted butter, softened (for frosting)
- 3 cups powdered sugar (for frosting)
- 1 tsp vanilla extract (for frosting)
Instructions
- Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
- In a medium bowl, whisk together flour, cornstarch, baking powder, baking soda, salt, and cinnamon.
- In a large bowl, beat butter, oil, and sugar until light and fluffy. Add eggs one at a time, beating well after each addition.
- Mix in vanilla extract and Greek yogurt until combined.
- Fold in mashed bananas and chopped walnuts.
- Gradually add dry ingredients to wet ingredients, mixing until just combined.
- Divide batter evenly between prepared pans and bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.
- Cool cakes in pans for 10 minutes, then turn out onto wire racks to cool completely.
- To make caramel sauce, combine sugar and water in a saucepan over medium heat. Cook without stirring until sugar turns amber in color.
- Remove from heat and carefully whisk in heavy cream, butter, and salt until smooth. Let cool to room temperature.
- For the frosting, beat cream cheese and butter until smooth. Gradually add powdered sugar and vanilla extract, beating until fluffy.
- Place one cake layer on a serving plate. Spread a layer of caramel sauce over it, then frost with cream cheese frosting.
- Top with the second cake layer, spread remaining caramel sauce, and frost the top and sides of the cake.
- Chill the cake for at least 1 hour before serving to set the frosting and caramel.
Notes
Use ripe bananas for maximum sweetness and moisture. The caramel sauce can be made ahead and stored in the refrigerator; warm slightly before using. Chilling the cake helps the frosting and caramel set nicely for cleaner slices.
