Heat oven to 350ºF. Grease a large loaf pan (9 ¼ x 5 ¼ inches) with cooking spray, and line with a strip of parchment if desired.
In a large mixing bowl whisk together the brown sugar, oil, vanilla and eggs until smooth. Add the pumpkin puree and milk and whisk until combined.
In another bowl stir together the flour, baking powder, baking soda, salt, pie spice and cinnamon. Add the dry ingredients to the wet ingredients and whisk together just until mixed. Stir in the walnuts.
Transfer the batter to the prepared pan and top the center of the loaf with extra walnuts. Bake for 1 hour, until bread springs back when touched on the top and a toothpick inserted comes out clean. Let cool about 15 minutes in the pan then remove to cool completely on a rack.
Meanwhile, make the glaze: Stir together the confectioners' sugar, maple syrup and cinnamon. Add a little water to make a glaze consistency. When bread is cool, drizzle with glaze.
Make Chocolate Chip Pumpkin Bread! Swap the walnuts for 1 cup chocolate chips. Then top the loaf with a few extra chocolate chips.Recipe by Tara Teaspoon
