1. Preheat the oven to 175°C (350°F). Grease and flour a bread loaf pan (9.25" x 5.25" x 2.75").

2. Lightly roast the walnuts in a skillet over medium heat, stirring continuously to prevent burning. Coarsely chop and cool to room temperature.

3. Cream together the butter and sugar in a mixing bowl until combined.

4. Mash the bananas with a fork until the consistency of chunky applesauce. Add to the batter along with the eggs and mix until blended.

5. Add the vanilla extract.

6. In a separate bowl, whisk together the flour, baking soda, and salt. Add to the batter and mix until combined.

7. Add chopped walnuts. Mix until combined.

8. Pour the batter into the prepared loaf pan. Bake at 175°C (350°F) for 55–60 minutes, or until a toothpick inserted into the center comes out clean.

9. Let the banana bread rest for 10 minutes before transferring to a wire rack to cool.
