01 - Preheat oven to 350°F and grease a 9x5-inch loaf pan or line with parchment paper.
02 - In a large mixing bowl, mash bananas until smooth. Add melted butter, eggs, and vanilla extract, stirring until well blended.

04 - Gradually add the dry ingredient mixture into the wet ingredients, stirring gently until just incorporated without overmixing.
05 - Gently fold in diced strawberries and chopped nuts, if using, ensuring even distribution.
06 - Pour batter evenly into the prepared loaf pan, smoothing the surface as needed.
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 remove to a wire rack to cool completely before slicing.
