Preheat and Prepare: Begin by preheating your oven to 300°F. Grease a loaf pan and set it aside.
Mix Dry Ingredients: In a mixing bowl, combine the flour, brown sugar, white sugar, cinnamon, salt, baking soda, and baking powder. Stir until well combined.
Blend Wet Ingredients: In a separate bowl, beat the eggs lightly. Add in the vanilla extract, vegetable oil, and milk, and whisk until fully incorporated.
Combine Wet and Dry: Gradually add the wet ingredients to the dry mixture, stirring until just combined. Be careful not to overmix; a few lumps are perfectly fine.
Fold in Pecans: Gently fold in the chopped pecans until evenly distributed throughout the batter.
Bake: Pour the batter into the prepared loaf pan, spreading it out evenly. Place it in the preheated oven and bake for 60 - 75 minutes, or until a toothpick inserted into the center comes out clean.
Cool and Serve: Once baked, allow the bread to cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely. Slice and serve either warm or at room temperature.
