Step 1: Preheat your oven to 350°F (175°C).
Step 2: Grease your 9x5 inch loaf pan with a little butter or non-stick spray.
Step 3: In a large mixing bowl, mash the ripe bananas until smooth. Then, add the melted butter, vanilla extract, and whisked eggs, mixing until well combined.
Step 4: In another bowl, whisk together the flour, sugar, baking powder, salt, cinnamon, and nutmeg until well distributed.
Step 5: Slowly add the dry mixture to the wet ingredients, folding gently with a spatula.
Step 6: Gently fold in the blueberries and chopped nuts until evenly distributed.
Step 7: Pour the batter into the prepared loaf pan, smoothing the top with the spatula.
Step 8: Place the loaf pan in the preheated oven and bake for 55-65 minutes, or until a toothpick comes out clean.
Step 9: Let the banana bread cool in the pan for about 10 minutes before transferring it to a wire rack.
