Preheat oven to 325°F. Grease and flour an 8 x 4″ loaf pan. You can also use a 9 x 5″ pan or mini loaf pans. In a medium bowl, mix together flour, baking powder, baking soda, pumpkin pie spice, and salt.
In a separate bowl, beat together oil, white sugar, brown sugar, vanilla extract, and eggs, until smooth. Finally, mix in the canned pumpkin.
With your electric mixer set to low, mix the flour mixture into the pumpkin mixture until smooth. Then, fold in the chocolate chips using a spoon or spatula.
Pour the batter into the prepared loaf pan.
Bake for 50-60 minutes in an 8 x 4″ loaf pan, 45-55 minutes in a 9 x 5″ loaf pan, or 20-30 minutes for mini loaf pans (5.75 x 3″ mini loaf pans). When done baking, the top will be slightly firm to the touch and a toothpick inserted in the center should come out clean. Serve, and enjoy!
