Prepare the Oven and Baking Dish: Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or non-stick spray.

Mix the Wet Ingredients: In a large bowl, stir together the granulated sugar, brown sugar, beaten eggs, and vegetable oil until fully combined.

Incorporate the Dry Ingredients: Stir in the self-rising flour and salt until well combined. Mix in the vanilla extract, then fold in the finely chopped pecans.

Bake the Pecanbread: Pour the batter into the prepared baking dish, spreading it evenly. Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out mostly clean.

Cool and Serve: Remove the dish from the oven and allow it to cool for at least 15 minutes before slicing. Serve warm or at room temperature.
