Preheat the Oven: Start by preheating your oven to 350°F (175°C). Grease a 9×5-inch loaf pan with butter or non-stick spray and set it aside.

Mix Wet Ingredients: In a large mixing bowl, combine the sugar, brown sugar, eggs, vegetable oil, and melted butter. Use a hand mixer or whisk to blend the ingredients until smooth and fully incorporated.

Add Dry Ingredients: Gradually add the self-rising flour to the wet mixture, stirring gently to avoid overmixing. Once the flour is incorporated, add the vanilla extract and mix until just combined.

Fold in Pecans: Gently fold in the chopped pecans using a spatula, ensuring they are evenly distributed throughout the batter.

Pour into Pan: Pour the batter into the prepared loaf pan, spreading it evenly with a spatula.

Bake: Place the pan in the preheated oven and bake for 50-60 minutes, or until a toothpick inserted into the center comes out clean.

Cool: Once baked, remove the loaf from the oven and let it cool in the pan for 10-15 minutes. Then, transfer it to a wire rack to cool completely before slicing.
