In a large bowl, whisk together the flour, cornmeal, sugar, baking powder, pumpkin pie spice, and salt.
In another bowl, whisk together the milk, pumpkin puree, egg, and melted butter until smooth.
Pour the wet ingredients into the dry and stir just until combined — a few lumps are fine. Add a splash more milk if the batter is too thick.
Heat a greased griddle or skillet over medium heat. Pour about ¼ cup batter per pancake.
Cook until bubbles form on top and the edges look set, about 2 to 3 minutes, then flip and cook 1 to 2 minutes more, until golden. Serve warm with syrup.
