Mix the dry ingredients
In a large mixing bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, and pumpkin pie spice until well combined. Set aside.
Blend the wet ingredients
In a blender, combine the pumpkin puree, brown sugar, egg, oil, and milk. Blend on high speed for about 45 seconds until smooth. If you don’t have a blender, whisk vigorously in a large bowl.
Combine wet and dry
Pour the wet mixture into the bowl of dry ingredients. Stir gently until just combined. Avoid overmixing—some lumps are totally fine. Fold in chocolate chips if using.
Preheat the griddle or skillet
Heat a nonstick skillet or griddle over medium heat (375°F if using an electric griddle). Lightly grease with butter or nonstick spray.
Cook the pancakes
Scoop ¼ cup of batter for each pancake onto the hot surface. Cook for 2–3 minutes until the edges set and small holes appear on the surface.
Flip and finish
Flip carefully and cook the other side for 1–2 more minutes, until golden brown and fully cooked through.
Serve warm
Serve immediately with toppings like butter, maple syrup, whipped cream, or toasted pecans. For a crowd, keep cooked pancakes warm in a 200°F oven while finishing the batch.
