A mini pumpkin pecan pie combined into one bite-sized cookie treat. If you love traditional Pecan Tassies and Thanksgiving pumpkin pie, then Pumpkin Pecan Tassies are destined to become a new favorite. These Tassies begin with a tender cream cheese pastry pressed into mini muffin pans, a filling made with pumpkin, spice, and a kick of rum, and finished with a brown sugar pecan topping.
