Step 1: Preheat your oven to 350°F (175°C) and prepare your loaf pan. Grease a 9x5-inch loaf pan with butter or cooking spray, then lightly flour it. This crucial step ensures your banana nut bread recipe won't stick and will release beautifully from the pan.
Step 2: In a large mixing bowl, thoroughly mash your very ripe bananas with a fork until mostly smooth but with a few small lumps remaining for texture. Don't overdo it; a little chunkiness is good! These mashed bananas are the star of this banana nut bread recipe, providing natural sweetness and moisture.
Step 3: To the mashed bananas, add the melted unsalted butter, granulated sugar, light brown sugar, and vanilla extract. Whisk these wet ingredients together until well combined. The sugars will dissolve slightly, creating a smooth base for your banana nut bread recipe.
Step 4: Crack the egg into the mixture and whisk until it is fully incorporated. The egg acts as a binder and adds richness to the banana nut bread recipe.
Step 5: In a separate medium bowl, whisk together the all-purpose flour, baking soda, baking powder, ground cinnamon, ground nutmeg, and salt. Ensure these dry ingredients are thoroughly combined to distribute the leavening agents and spices evenly throughout your banana nut bread recipe.
Step 6: Gradually add the dry ingredients to the wet ingredients, mixing with a spatula or wooden spoon until just combined. Be careful not to overmix! Overmixing develops the gluten in the flour too much, which can lead to a tough, chewy banana nut bread recipe instead of a tender one. A few streaks of flour are perfectly fine.
Step 7: Gently fold in the toasted chopped walnuts. Distribute them evenly throughout the batter. This is where the "nut" in this banana nut bread recipe truly shines, adding delightful crunch and flavor.
Step 8: Pour the batter into your prepared loaf pan, smoothing the top with your spatula. If you wish, you can sprinkle a few extra chopped walnuts on top for a nice visual appeal and added crunch. This makes your banana nut bread recipe look extra special.
Step 9: Bake for 55-65 minutes, or until a wooden skewer or toothpick inserted into the center of the loaf comes out clean. Baking times can vary depending on your oven, so keep an eye on it. If the top starts to brown too quickly, you can loosely tent it with aluminum foil. This step is critical for a perfectly baked banana nut bread recipe.
Step 10: Once baked, remove the loaf pan from the oven and let the banana nut bread cool in the pan for about 10-15 minutes on a wire rack. This allows the bread to set and prevents it from crumbling when removed.
Step 11: After cooling slightly, carefully invert the loaf onto the wire rack to cool completely before slicing and serving. Cooling completely ensures the crumb fully sets and the flavors meld perfectly. Enjoy your homemade banana nut bread recipe!
