Preheat oven to 175°C. Grease or line a 23×13-centimetre loaf pan with parchment paper for easy removal.
02 -
In a large mixing bowl, thoroughly whisk together flour, cocoa powder, baking soda, baking powder, salt, cinnamon, nutmeg, and cloves until evenly combined. Set aside.
03 -
In a separate bowl, blend pumpkin puree, granulated sugar, brown sugar, eggs, vegetable oil, Greek yogurt (or sour cream), and vanilla extract. Whisk until smooth and homogenous.

Gradually fold the dry ingredients into the wet mixture. Use a spatula to mix until just combined—avoid overmixing to maintain a tender crumb.
05 -
Gently fold in the semi-sweet chocolate chips and optional chopped dark chocolate, reserving a small handful for topping.
06 -
Pour the batter into the prepared loaf pan. Scatter reserved chocolate chips over the top. Transfer to the oven and bake for 55–65 minutes, until a toothpick inserted in the centre emerges with only a few moist crumbs.

Allow the bread to cool in the pan for 10 minutes. Remove from the tin and place on a wire rack to cool completely before slicing.
