Heat a large griddle or skillet to medium high heat, about 350 degrees. Spray with nonstick spray.
In a large bowl, mix together your flour, baking powder, baking soda, salt, cinnamon, pumpkin pie spice, and chocolate chips. Stir to combine, and set aside.
In another bowl combine your pumpkin puree, brown sugar, egg, butter and milk. Whip everything together till combined.
Dump your dry ingredients in with your wet ingredients and stir until everything is just combined. (The batter is supposed to be thick)
Pour about 1/4 cup of batter onto the griddle, spread out a little to form a circular shape.
Cook until the edges are starting to look cooked, about 2 minutes, then flip and cook on the other side till cooked through. (Another minute or 2).
Repeat with additional batter.
Serve pancakes with butter and syrup.
