Preheat the oven to 425°F. Lightly grease 2 muffin pans or fill them with cupcake liners and set aside.
In a medium-sized bowl, combine flour, cinnamon, pumpkin pie spice, baking soda, baking powder, salt, and sifted cocoa powder. Set aside.
In a larger mixing bowl, whisk the eggs and add the vanilla, butter, pumpkin puree, milk, brown sugar, and sugar together until well combined.
Stir the flour mixture into the pumpkin mixture.
Scoop the batter into the muffin tin.
Bake in the center of the oven for 5 minutes and then turn the oven to 350° F and bake for an additional 10 to 12 minutes or until a toothpick comes out clean or with just a few crumbs.
Remove the pan from the oven, and let cool in the pan for 5 minutes, and then remove the muffins from the pan to a cooling rack.
Notes
A 20oz can of pureed pumpkin is enough to double this recipe.An offset spatula or a knife works well to remove baked muffins from the pan.To store: Let the muffins cool completely, then store them in an airtight container or resealable bag at room temperature for up to 5 days. Skip the fridge — the cold air causes condensation that makes these muffins go soggy.To freeze: Place cooled muffins in a freezer-safe bag or container for up to 3 months. Freeze them in a single layer first if you want to grab just one or two at a time later.To reheat: Microwave in 10-second bursts just until warmed through. Any longer and you'll melt the chocolate chunks completely instead of leaving them soft and gooey.
