Pumpkin Cookies from Thanksgiving

INGREDIENTS ½ cup butter
1 cup vegetable oil
2 cups white sugar
2 eggs beaten
2 teaspoons vanilla extract
3 cups pumpkin puree almost a whole large can
6 cups all-purpose flour
2 teaspoons baking powder
2 teaspoons baking soda
1 teaspoon salt
2 teaspoons ground cinnamon
½ tsp ginger
½ tsp cloves
About ½ bag chocolate chips
About ½ cup butterscotch chips

DIRECTIONS
Preheat the oven to 350 F (175 degrees C).
Cream together the margarine, vegetable oil and sugar.
Beat together the egg, vanilla and pumpkin.
Sift together the flour, baking powder, baking soda, salt and cinnamon; combine with pumpkin mixture and stir in chips
Drop onto ungreased cookie sheet and bake for 10 to 12 minutes. (I used my cookie scoop and flattened the top to make them uniform and small) Be careful not to overbake.

Since then, I have started cutting the oil to 3/4 cup and then just dumping the whole large can of pumpkin in.  It works great.  Also, I sometimes add more butterscotch chips as well.
