Mix flour, cinnamon, apple pie spice, salt and yeast in a mixer. In a separate bowl mix pumpkin, 2/3 C brown sugar and warm water. Make a well in the dry ingredients and add the wet. Stir until a dough forms. Knead for 10 minutes or use the dough hook on your mixer until a firm dough ball forms. Place in an oiled bowl, turning once to coat the whole dough ball in oil. Cover with plastic wrap and let rise in a warm spot for 1 hour. Punch down and knead a few times. Cut into 3 pieces. Roll each piece into a long roll. Cut into 5 pieces. Form into circles and pinch ends together. Cover with a towel and let rise 20 minutes. Meanwhile start a large pot of water to boil, add 2 tbsp brown sugar. After the bagels have rested and are nice and puffy drop a few bagels at a time into the boiling water. Poach for 1 minute turning once with a wooden spoon. Set on a greased cookie sheet. Sprinkle with cinnamon sugar topping mixture and bake at 500 for 10 - 15 minutes.
