Step 1

Preheat oven to 350 degrees F. Coat 2 baking sheets with cooking spray.

Step 2

Whisk whole-wheat flour, all-purpose flour, pumpkin pie spice, baking powder, baking soda and salt in a large bowl. Whisk brown sugar, eggs, pumpkin puree, butter, oil and vanilla in a medium bowl. Stir the wet ingredients and chocolate chunks (or chips) into the dry ingredients until well combined.

Step 3

Drop the batter by the level tablespoonful onto a prepared baking sheet, spacing the cookies about 1 1/2 inches apart. Bake until firm to the touch and lightly golden on top, 10 to 13 minutes. Transfer to a wire rack to cool.
