Preheat oven to 350° and spray miniature muffin cups with nonstick cooking spray or use mini muffin liners.
In a medium bowl, mix the flour, pumpkin pie spice, cinnamon, salt, baking soda, and baking powder and set aside.
In the bowl of a stand mixer cream the butter and the sugar until fluffy, about two minutes. Add eggs one at a time mixing well after each addition. Add the pumpkin and mix until well combine.
Add the dry ingredients mixing just until combine. Stir in chocolate chips.
Fill muffin cups ¾ full with batter. (I used a #50 scoop.)
Bake 10 to 11 minutes until a toothpick inserted in center comes out clean. Cool for 1 minute before transferring bites to a wire rack. (Bake 35-40 minutes for the mini loaves.)
Notes
Substitute ½ teaspoon ground cinnamon plus ¼ teaspoon ground ginger, ¼ teaspoon ground nutmeg and ⅛ teaspoon ground cloves for 1 teaspoon pumpkin pie spice.*I used Halloween chocolate chips**I made 48 bites and two mini loaf pans - 5 ¾ x 3 ¼ x 2 ¼.
