01 - Preheat oven to 350°F (175°C). Grease a 9x5-inch loaf pan or line with parchment paper.
02 - In a large mixing bowl, mash the ripe bananas until smooth. Incorporate the melted butter, eggs, and vanilla extract, stirring until well blended.
03 - In a separate bowl, whisk together the all-purpose flour, granulated sugar, baking soda, and salt until homogeneous.
04 - Gently add the dry mixture to the wet ingredients, stirring until just combined. Avoid overmixing to ensure optimal texture.
05 - Fold in the diced strawberries and, if desired, chopped nuts. Mix until evenly distributed.
06 - Pour the batter into the prepared loaf pan, spreading evenly.
07 - Bake for 50 to 55 minutes, or until a toothpick inserted in the center emerges clean.
08 - Allow bread to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.
