Add the vanilla pudding, pumpkin puree, eggs, and pumpkin pie spice into a bowl. Mix well to combine.
Add in the spice cake mix and mix until just blended. Overmixing the batter will cause the middle to sink in more. Mix in the chocolate chips if using.
Grease a 9x5 loaf pan and scoop the pumpkin bread batter into the pan.
Place in the oven and cook for 50-60 minutes until a toothpick comes out clean.
Let the pumpkin bread cool for at least 10 minutes then remove from the loaf pan.
