Preheat oven to 375 degrees.

Beat the butter with a mixer until creamy. Then, add in the sugars and beat until well mixed.

Add in eggs, pumpkin puree, and vanilla. Mix again until ingredients are well combined.

In a separate mixing bowl, mix all dry ingredients (except the chocolate chips and nuts). Slowly incorporate the combined dry ingredients into the wet ingredients, mixing as you add.

Add the chocolate chips and pecans to your dough.

Form dough into 2 inch balls and place on cookie sheet. Press the dough balls down (similar to peanut butter cookie dough) to make flat cookies. If you do not flatten the dough, they will be a very puffy cookie and may not bake properly.

Bake for 8-12 minutes or until lightly browned.

Remove from oven and let cool for a few minutes on the baking sheet before putting them on a wire rack to cool.
