In a large bowl, whisk together flour, sugar, salt, baking powder, baking soda, and pumpkin spice. Set aside.

In a medium bowl, add eggs and beat them slightly. Add buttermilk, pureed pumpkin, and melted butter and mix to combine.

Add wet ingredients to dry ingredients and mix until the batter is mostly smooth, with only small bits of flour remaining. Fold in chocolate chips. Be sure not to over mix the batter.

Meanwhile, heat a griddle or skillet over medium heat. Melt butter into skillet or spray with baking spray, adding more as the pancakes cook to make sure that the griddle or skillet is well coated at all times.

Add about 1/3 cup batter to the hot pan. Cook approximately 2-3 minutes per side.

Serve pancakes warm with maple syrup and butter.
