Set your oven to 350°F (175°C) to ensure even baking and a perfectly cooked cake.
Thoroughly grease and flour a Bundt pan to prevent the cake from sticking and ensure it comes out cleanly after baking.
In a bowl, mash three ripe bananas until smooth. This will add natural sweetness and moisture to your cake.
In a large bowl, blend together the mashed bananas, 1 cup of sugar, 2 large eggs, 1/2 cup of melted butter, and 1 teaspoon of vanilla extract until well combined.
In a separate bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of baking soda, 1 teaspoon of baking powder.
Gently fold in 1 cup of chopped walnuts into the dry mixture. The walnuts add a delightful crunch and nutty flavor to the cake.
Gradually mix the dry ingredients into the wet ingredients, stirring until just combined. Be careful not to overmix to keep the cake tender.
Pour the batter into the prepared Bundt pan and bake for 50-60 minutes, or until a toothpick inserted into the center comes out clean.
