Preheat oven to 350°F (177°C). Grease/spray two mini muffin pans with nonstick cooking spray. This recipe makes around 36 muffins, so you will only use half of the 2nd pan. If using mini liners, grease/spray them with cooking spray. Set pans aside.

In a large bowl, whisk the flour, baking powder, baking soda, salt, cinnamon, and pumpkin pie spice together. Set aside. In a medium bowl, whisk the eggs, brown sugar, pumpkin puree, melted butter, vanilla, and milk together until combined. Pour the wet ingredients into the dry ingredients, stir a few times, then add the mini chocolate chips. Fold everything together gently just until combined.

Fill muffin cups around 3/4 – all the way full. Go for about 1 heaping Tablespoon of batter per muffin. Bake for 12-14 minutes or until a toothpick inserted into the center comes out clean. If your oven has hot spots, be sure to rotate the pans during bake time. My muffins took 12 minutes. Remove pans from the oven. Allow muffins to slightly cool before enjoying.
