Preheat Oven to 350 degrees. Generously grease two (2) 9 1/4" x 5 1/4" x 2" loaf pans. In a large bowl, mix together flour, sugar, baking soda, pumpkin pie spice, salt and baking powder. I a second bowl stir together remaining ingredients until well mixed. Add pumpkin mixture to flour mixture and stir until all ingredients are well moistened. Pour batter into loaf pans. Bake 65 minutes or until breads test done with wooden pick. Cool in pans 10 minutes then remove to cooling racks. Completely cool breads then drizzle glaze over top and sides. Makes 2 loaves. Glaze: In a small bowl, with fork, mix 1 cup powdered sugar, 1/4 cup undiluted orange juice concentrate and 1/8 teaspoon allspice, until smooth. Drizzle over the cooled breads.
(To be perfectly accurate I use this orange juice glaze on many items during the course of 2 weeks, so I use a 6 oz can of frozen oj concentrate, effectively tripling the recipe. This is a hint). *use Ocean-Spray 16 oz can, if available.
