Preheat oven to 350 degrees.
Prepare a 9 ¼ X 5 ¼ loaf pan with parchment paper. Set aside.
In a medium sized mixing bowl add the Spice Cake Mix and the 2 cups of canned pumpkin.
Using a wooden spoon, stir until well blended.
The batter will be very thick.
Add the bread batter to the prepared loaf pan.
Bake in a preheated 350 degree oven for 35 minutes or until a toothpick inserted in the middle of the bread comes out clean.
Allow to cool on a baking rack for 10 minutes before sprinkling with powdered sugar.
