Preheat oven to 350 degrees Fahrenheit. Grease a 9 x 5-inch loaf pan with nonstick cooking spray and set aside.
In a large bowl, mix together, 2 eggs, 1 ¼ cups sugar, ½ cup oil, 1 (15-ounce) can pumpkin, ¼ cup buttermilk and 2 teaspoons vanilla extract. Mix until evenly combined.
In a medium bowl, whisk together 2 cups flour, ½ teaspoon baking soda, 1 teaspoon baking powder, 1 teaspoon salt, 2 teaspoons cinnamon, ½ teaspoon nutmeg, ¼ teaspoon cloves, and ¼ teaspoon ginger.
Gently fold the dry mixture into the wet, mixing until just combined. A few lumps are okay, don't overmix. Stir in 1 cup semi-sweet chocolate chips.
Pour the batter into the prepared pan. Bake for 55-60 minutes. The bread is done when a toothpick inserted in the center comes out with just a few moist crumbs. Cool in the pan for 10 minutes before removing to a wire rack to cool completely before slicing.
Notes
To Store or Freeze: Once cooled, wrap bread tightly or place in an airtight container. Store at room temperature for 3–4 days, in the fridge for up to 1 week, or freeze for up to 3 months.
