Preheat the oven to 350°F. Spray a 9x5 loaf pan with cooking spray and line it with a small piece of parchment paper. Set the pan aside.
Whisk the flour, pumpkin pie spice, baking powder, salt, and baking soda together in a small or medium bowl.
In a separate large mixing bowl, use an electric mixer to combine the oil, sugar, and light brown sugar until it’s fluffy. Mix in the pumpkin puree, then add the eggs and vanilla extract and continue mixing until the eggs are just mixed.
Pour in the dry ingredients and blend until everything is well-mixed. Fold in the chocolate chips, then pour the batter into the greased loaf pan until the pan is ¾ full or about 1 inch from the top of the pan. Bake for 1 hour and 30 minutes or until a thin knife inserted in the middle comes out clean.
Let the bread rest for 20-30 minutes before slicing and serving.
