Step 1

Preheat oven to 325 degrees F (165 degrees C). Lightly grease two 8x4 inch loaf pans.

Step 2

In a medium bowl, combine cream cheese, 1/2 cup sugar, 1 tablespoon flour, 1 egg and orange zest; beat until smooth. Set aside. Sift together 1 2/3 cup flour, baking soda, salt, cinnamon, cloves and pumpkin pie spice; set aside

Step 3

Place pumpkin, vegetable oil, 2 eggs and 1 1/2 cup sugar in a large bowl; beat well. Stir the pumpkin mixture into the flour mixture just until combined. Fold in the pecans if desired. Pour 1/2 of the pumpkin batter into the loaf pans. Spoon cream cheese mixture on top of this layer and then pour on the remaining batter.

Step 4

Bake in preheated oven for 60 to 70 minutes, or until a toothpick inserted into center of the loaf comes out clean. Cool bread in pans for 10 minutes before removing to a wire rack to cool completely.
