Preheat your oven to 350°F (175°C) and prepare a 9x13-inch baking dish.

In a large mixing bowl, combine granulated sugar, light brown sugar, vegetable oil or melted butter, and eggs. Whisk until smooth.

In another bowl, whisk together all-purpose flour, baking powder, and salt. Then fold the dry mixture into the wet mixture.

Gently fold in the chopped pecans until evenly distributed.

Pour the batter into the prepared baking dish and bake for 30–35 minutes until golden and a toothpick comes out clean.

Allow to cool in the pan for about 10–15 minutes before slicing and serving.
