Step 1: Prepare the Oven and Pan
Preheat your oven to 325°F (163°C). Grease and flour a standard 9×5-inch loaf pan (or two 8×4 pans for smaller loaves). You can also use baking spray with flour for a non-stick finish.

Step 2: Toast the Pecans (Optional but Recommended)
In a dry skillet, toast the chopped pecans over medium heat for 5–7 minutes, stirring occasionally, until they are fragrant and slightly darker in color. This step enhances the flavor significantly. Let them cool before adding to the batter.

Step 3: Combine the Dry Ingredients
In a large mixing bowl, whisk together the flour, sugar, baking soda, salt, cinnamon, and nutmeg. This ensures that all the dry ingredients are evenly distributed.

Step 4: Mix the Wet Ingredients
In a separate medium bowl, beat the eggs until frothy. Add the oil, vanilla extract, and buttermilk. Whisk together until the mixture is smooth and fully combined.

Step 5: Combine Wet and Dry Mixtures
Gradually add the wet ingredients to the dry mixture. Stir just until combined — do not overmix, as this can make the bread tough. The batter will be thick and slightly lumpy.

Step 6: Fold in the Pecans
Gently fold in the chopped, toasted pecans using a spatula. Make sure they’re evenly distributed throughout the batter for consistent crunch in every bite.

Step 7: Pour and Bake
Pour the batter into your prepared loaf pan(s), spreading it evenly. If you’re using the topping, sprinkle the cinnamon sugar and chopped pecans on top, then drizzle with melted butter. Bake for 55–65 minutes, or until a toothpick inserted in the center comes out clean.

Step 8: Cool and Serve
Allow the bread to cool in the pan for about 10 minutes, then transfer to a wire rack to cool completely. This prevents the bottom from becoming soggy and allows the crust to stay slightly crisp.
