Preheat oven to 350 degrees.
Line 8.5" bread pan with parchment paper. Think making a sling for the bread. I recommend letting the parchment paper hang out of the long sides of the pan about 2", so you can grab the sides and remove the bread easily without it sticking. Alternatively, you can grease the pan well. There is not much fat in this bread, so it will stick if you do not line it with parchment or grease very well.
Combine pumpkin, eggs, brown sugar, maple syrup, milk and vanilla extract in a medium bowl. Mix well.
Add pancake mix, cinnamon, and pumpkin pie spice. Stir until combined.
Decide if you want to add chocolate chips or crumble topping. If using chocolate chips: stir most of the chips into the batter saving a few for the top.
Pour batter evenly into prepared pan. If using the crumble topping: combine all ingredients into a small bowl. Stir well. Sprinkle topping evenly over the batter.
Bake for 50-55 minutes or until a toothpick inserted into the center of the bread comes out clean. Note: different pans and ovens can alter the bake time. Check your bread until fully cooked.
Allow bread to cool slightly before cutting. Store extra on the counter for 48 hours. Or, if you want to keep it longer store in the refrigerator for 2 weeks or freeze for 3 - 4 months.
