Preheat your oven to 350°F (175°C).
In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition, followed by the pumpkin puree.
In a separate bowl, whisk together the flour, baking powder, spices, and salt.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Avoid overmixing.
Fold in the chocolate chips until evenly distributed.
Pour the batter into a greased or lined baking pan of your choice.
Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
Let the baked goods cool in the pan for about 10 minutes before transferring to a wire rack.
Once completely cooled, you may frost or decorate as desired for Halloween.
