Add the flour, cocoa, cinnamon, baking powder, baking soda, and salt to the mixing bowl. Mix again until just combined. A few streaks of flour are fine.
260 grams (1 ¾ cups) whole grain spelt flour, 20 grams (¼ cup) cocoa powder, 2 teaspoons cinnamon, 2 teaspoons baking powder, ½ teaspoon baking soda, ¼ teaspoon sea salt
Fold in the chocolate and seeds to evenly distribute.
100 grams (½ cup) dark chocolate, chopped, 50 grams (¼ cup) raw sunflower seeds
Transfer the batter to the prepared loaf tin and bake for 55-60 minutes, or until the loaf passes a skewer test. Remove from the oven and cool on a wire rack for about 15 minutes before carefully removing from the tin and cooling fully before slicing.
Keep the loaf in a sealed container at room temperature for a couple of days, or refrigerate up to a week. Pumpkin bread freezes well.
