Creating the Banana Walnut Caramel Pecan Cake can be effortless by following these clear steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan.

3. Add Egg & Vanilla: Beat in the egg and vanilla extract until thoroughly combined.
4. Incorporate Bananas: Stir in the mashed bananas until the mixture is smooth.
5. Combine Dry Ingredients: In another bowl, whisk together the flour, baking soda, and salt.
6. Mix Dry and Wet: Gradually add the dry ingredient mixture to the banana mixture, stirring until just combined.
7. Add Nuts: Gently fold in the chopped walnuts and pecans, making sure they are evenly distributed throughout the batter.
8. Pour Batter: Pour the batter into the prepared cake pan and smooth the top with a spatula.
9. Bake: Place in the preheated oven and bake for 40-45 minutes or until a toothpick inserted in the center comes out clean.
10. Cool: Once done, remove the cake from the oven and allow it to cool in the pan for 15 minutes. Then, transfer it to a wire rack to cool completely.
11. Add Caramel: Once the cake is cool, drizzle the caramel sauce over the top and sprinkle with additional chopped nuts for garnish.
