Preheat the oven to 350 degrees F and line a 9x5 inch loaf pan with parchment paper.
In a pan over low heat add the butter and chocolate chips and mix together as the butter melts.
Add the flour, baking soda, baking powder, salt and spices and mix.
Add pecans and ¾ cup of chocolate chunks and fold through the batter.
Add the batter to the prepared loaf pan and spread it out evenly.
Sprinkle the remaining ¼ cup of chocolate chunks on top of the loaf.
Bake in the oven for 60-70 minutes or until the top of the bread feels firm when gently pressed with your finger. If it still feels wet it may need another five minutes.
