- Preheat your oven to 350°F (175°C). Grease a standard loaf pan and set aside. 
- In a large mixing bowl, whisk together the flour, granulated sugar, light brown sugar, baking soda, cinnamon, cardamom, and salt until evenly combined. 
- In a separate bowl, stir together the pumpkin puree, vegetable oil, and eggs until smooth and slightly frothy. 
- Gradually pour the wet mixture into the dry ingredients, gently folding with a spatula until just combined. Do not overmix; the batter should be a bit lumpy. 
- Stir in the orange zest and chopped pecans evenly into the batter for added flavor and crunch. 
- Pour the batter into the prepared loaf pan, smoothing the top with a spatula for an even surface. 
- Bake in the preheated oven for about 50 minutes, or until a toothpick inserted into the center comes out clean and the top is golden brown. 
- Remove the bread from the oven and let it cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. 
- Once cooled, slice the bread to reveal a moist crumb dotted with pecans and flecks of orange zest.
