Preheat your oven to 350°F (175°C) and prepare a 9x5 inch loaf pan by greasing it or lining it with parchment paper.

In a mixing bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt until well combined.

In another bowl, mix pumpkin puree, water, oil or almond butter, and vanilla extract until smooth.

Fold the wet ingredients into the dry mixture until just combined to form a thick batter.

Transfer the batter to the prepared loaf pan and optionally sprinkle mini chocolate chips on top.

Bake for approximately 40 minutes or until a toothpick inserted comes out mostly clean.

Let the bread cool in the pan for about 10 minutes, then transfer to a wire rack to cool completely.
