In a large mixing bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt.
Add in the egg, melted butter, brown sugar, vanilla extract, buttermilk, pumpkin puree, and pumpkin pie spice. Mix until smooth.
Heat a non-stick pan over medium heat. Once hot, reduce the heat slightly.
Spray the pan with oil or coat it with butter. Pour about 1/3 cup of batter onto the pan.
Cook for 2 to 3 minutes on the first side until bubbles start to form on the top. Flip and cook until both sides are golden.
Repeat until all the batter is used.
Serve warm with maple syrup, powdered sugar, and a dollop of cinnamon butter on top.
