In a medium bowl, mix the flour, spices, salt, baking soda, and baking powder.
In the bowl of a stand mixer, cream the butter and the sugar until fluffy, about two minutes. Add the eggs one at a time, mixing well after each addition. Add the pumpkin and mix until combined.
Add the dry ingredients to the stand mixing bowl, mixing just until combined. Stir in the chocolate chips.
Pour the mixture into the prepared pan(s). Bake the half Bundt pans for 35-40 minutes; bake the full size Bundt for 50-60 minutes or until a toothpick comes out clean.
Cool in the pans for 5 minutes on a wire rack. After 5 minutes, invert the cake(s) onto the wire rack. Cool completely before serving.
