Preheat oven to 350 degrees. Spray non stick spray into a 9x5 loaf pan.
In a bowl, mix together the pumpkin, eggs, sugar, vanilla.
Add to the pumpkin mixture, the flour, baking soda, baking powder, and spices. Mix together until the pumpkin and flour mixture is well incorporated.
Pour half of the pumpkin bread mixture into the bottom of the prepared loaf pan.
In a small bowl, combine room temperature cream cheese, sugar, egg and vanilla and mix well.
Gently spread the cream cheese mixture over the pumpkin bread mixture.
Pour the remaining pumpkin bread mixture over the cream cheese mixture and spread out gently.
Sprinkle chopped, walnuts over the top of the pumpkin batter and place bread into a preheated oven.
Bake 1 hour and check for doneness by inserting a toothpick into the middle. If the toothpick comes out clean, remove bread from oven. If there is wet batter on the toothpick, place bread back into oven for 5 more minutes and recheck doneness again.
When bread is done, remove from oven and let cool 15 minutes before removing from loaf pan and placing on wire rack to completely cool.
Once cool, slice and enjoy. Store in an airtight container.
