In a medium size bowl, cream together the sugars and butter. Add the pumpkin and mix well. Add in all of the spices, then the flour. Mix well.
Use a mini cookie scoop to place a ball of cookie dough into mini muffin pans that have been sprayed with cooking spray. You should get about 36 cookies.
Bake for 7-8 minutes. The cookie dough will be puffy and soft to the touch. Turn off the oven, remove the cookies and immediately press a Rolo in the center of each cookie.
Return the pan to the oven for just 1 minute.
Remove the pan once again and press a pecan half into the soft chocolate.
Allow the cookies to cool in the pans for 10 minutes, then remove them to a wire rack to cool completely.
