I found this recipe on A Southern Grace's blog and I finally got around to making these little beauts last night.  Below is the original recipe, but I used whole wheat flour instead and a little less cinnamon.  I also used light brown sugar and put in more than a cup of chocolate chips. Mine were so good I can't stop myself from eating them, so I don't think the whole wheat made much of a mark.

Make them. Now. Do it for yourself. What a great Sunday treat!  

2 cups all-purpose flour
1 1/3 cups quick or old-fashioned oats
1 teaspoon baking soda
2 teaspoons ground cinnamon
1/2 teaspoon salt
1 cup (2 sticks) butter, softened
1 cup packed brown sugar
1 cup granulated sugar
1 cup pumpkin puree
1 large egg
1 teaspoon vanilla extract
1 cup chocolate chips

Preheat oven to 350° F. Lightly grease baking sheets or line them with parchment paper.
Combine flour, oats, baking soda, cinnamon and salt in medium bowl. Beat butter, brown sugar and granulated sugar in large mixer bowl until light and fluffy. Add pumpkin, egg and vanilla extract; mix well. Add flour mixture; mix well. Stir in chocolate chips. Drop by rounded tablespoons onto prepared baking sheets.
Bake for 14 to 16 minutes or until cookies are lightly browned and set in centers. Cool on baking sheets for 2 minutes; remove to wire racks to cool completely.
