Preheat oven to 350°F. Grease a muffin tin or fill with muffin liners.
In a medium bowl, whisk together flour, baking soda, salt, and pumpkin pie spice.
In a large bowl, whisk together pumpkin, maple syrup, extra-light tasting olive oil, eggs, and water.
Gradually add the dry mixture to the wet mixture. Stir until just mixed.
Fold in ½ cup chocolate chips.
Divide batter into muffin tins and sprinkle with the remaining 2 tablespoons chocolate chips.
Bake for 30-35 minutes or until a toothpick inserted in the middle comes out clean.
Allow muffins to cool for 10 minutes before carefully removing.
Serve muffins while they are still warm. Or, transfer muffins to a wire rack and cool completely before storing.
