Preheat oven to 350 degrees and spray a muffin tin with non-stick cooking spray or line with muffin tins. Set aside.

In a large mixing bowl, mix together the eggs, milk and oil. Stir in the pumpkin puree, light brown sugar, granulated sugar. Gently fold in the flour, pumpkin pie spice, and the baking powder.

Fill the muffin tins with the batter ¾ of the way. Bake for 17 minutes. Allow the muffins to cool for 10 minutes, then transfer to a cooling rack.
