Preheat oven to 350.
Grease a Bundt cake pan with non-stick spray or butter, dust with flour, then tap out any excess.
In a large bowl sift together the flour, baking soda, baking powder, salt and pumpkin pie spice.
In a separate mixing bowl, with an electric mixer, beat together the butter and sugar for 2 minutes.
Add the eggs and continue to mix until bright yellow and smooth.
Slowly pour and mix in the pumpkin puree.
Gradually add half of the flour mixture into the pumpkin mixture.
Pour in the milk and add in the rest of the flour mixture.
Beat until well incorporated.
Pour the batter into the prepared Bundt pan, smooth the top, then bake the cake for 50 to 60 minutes, or until a toothpick inserted into the center comes out clean and the cake has begun to pull away from the sides of the pan.
