Preheat oven to 350 degrees. Lightly grease a large loaf pan.
In a large bowl mix flour, sugar, pumpkin pie spice, baking soda, baking powder, and salt.
Combine blended eggs, canned pumpkin, and butter in another bowl.
Gently mix wet ingredients into dry ingrediants.
Stir in chocolate chips.
Pour batter into greased loaf pan. This recipe will make 1 loaf if you are using a large nonstick loaf pan. It will make 2 loaves if using the smaller glass loaf pans.
Bake at 350 degrees for 55 to 60 minutes or until a tooth pick inserted into center of loaf comes out clean. This can be a bit difficult with the chocolate chips.
Let cool for 10 minutes and then remove from pan to a wire rack.
