Preheat your oven to 350 degrees F. Grease a loaf pan generously with nonstick cooking spray or butter, set aside.
In a medium bowl, whisk together the all-purpose flour, baking soda, kosher salt, cinnamon, nutmeg, ginger, and cloves. Set aside.
In a large bowl, whisk together the pumpkin, brown sugar, granulated sugar, eggs, melted butter, oil, buttermilk, and vanilla extract. Mix until smooth.
Add the dry ingredients to the wet mixture and gently fold them in. Be careful not to overmix; a few lumps are okay.
Pour the batter into the prepared loaf pan and smooth the top. Sprinkle generously with turbinado sugar.
Place the loaf pan in the oven and bake for 45 to 60 minutes. Check for doneness with a toothpick; if it comes out clean, it’s ready!
Remove from the oven and let cool in the pan for about 10 minutes before transferring to a cooling rack.
Loosen the edges with a butter knife and turn it out of the pan. Allow to cool completely before slicing.
When fully cooled, slice with a serrated knife and enjoy your Pumpkin Bread!
