For a deeper flavor, toast the pecans lightly before chopping and adding them to the pie bites. Be careful not to overbake the filling; it should be set but still slightly soft to the touch. The pie bites can be stored in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week. A dash of bourbon or rum extract can be added to the filling for a more complex flavor profile. Dust with powdered sugar before serving for an elegant finish.
