In a large bowl, mix the flour, baking powder, cinnamon, nutmeg and salt.
In another bowl, whisk the eggs and sugar until you have a light mixture.
To the egg mixture, add the pumpkin puree, milk, syrup and melted butter and mix until homogeneous.
Heat the waffle iron and lightly brush the top and bottom with oil using the grease brush. Also prepare a baking tray so your waffles can cool.
Divide the dough between the baking sheets and close the appliance.
Bake the waffles until golden brown (2:30 min at setting 5)
