Step 1: Preheat and Prepare: Preheat oven to 350F (175C). Grease and flour a 9x5 inch loaf pan. This ensures the bread releases easily after baking.
Step 2: Combine Dry Ingredients: In a medium bowl, whisk together the flour, baking soda, cinnamon, nutmeg, and salt. This step evenly distributes the leavening agent and spices.
Step 3: Cream Butter and Sugar: In a separate large bowl, whisk together the melted butter and brown sugar until smooth. A smooth base ensures even sweetness throughout the bread.
Step 4: Add Eggs and Vanilla: Beat in the eggs one at a time, then stir in the vanilla extract. Incorporating eggs gradually ensures proper emulsification and a tender crumb.
Step 5: Incorporate Bananas: Stir in the mashed bananas until just combined. Avoid overmixing at this stage to prevent a tough texture.
Step 6: Combine Wet and Dry Ingredients: Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Again, be careful not to overmix.
Step 7: Pour into Pan and Bake: Pour the batter into the prepared loaf pan and bake for 50-60 minutes, or until a wooden skewer inserted into the center comes out clean. A clean skewer indicates that the bread is fully cooked.
Step 8: Cool and Serve: Let the bread cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. Slicing while still warm can lead to a gummy texture.
Optional: For a richer flavor, add cup of chopped walnuts or pecans to the batter. Chocolate chips also make a delightful addition. If using whole wheat flour, consider adding an extra tablespoon of milk or water if the batter seems too thick.
