Preheat a waffle iron on medium high heat (I set my heat on 5, out of 7)

In a large mixing bowl, stir together the flour, sugar, baking powder and spices.

In a small bowl, whisk together the melted butter, milk, eggs, and pumpkin.

Pour the wet ingredients into the dry and whisk until smooth.

Spray the waffle iron with nonstick cooking spray and ladle in the battler, being careful not to overfill.

Cook the waffles until browned and crispy. Remove from the oven and repeat with remaining batter.

Serve with butter and syrup.
