Preheat the waffle iron according to the manufacturer’s instructions.
In a large bowl, whisk together the flour, baking powder, and pumpkin pie spice.
In another bowl, whisk together the egg, pumpkin puree, milk, melted butter, and maple syrup.
Add the wet ingredients to the dry and whisk just until no large lumps of flour remain. You don’t want to overmix!
Once the waffle iron is preheated, grease it lightly with nonstick baking spray and add ½ cup of batter to the waffle iron.
Cook for 3-4 minutes or until the waffle is crisp on the outside and fully cooked in the center-- you can always insert a toothpick into the waffle to make sure it comes out clean.
Repeat steps 5 and 6 with the remaining batter.
Serve garnished with your favorite toppings. Enjoy warm.
Store any leftover waffles in an airtight container in the fridge for up to two days.
