Preheat your waffle maker according to the manufacturer's instructions. Oil with coconut oil if desired (not necessary though).

In a small bowl, mix the sugar, starch, flour, baking powder, salt and spices with a whisk until all lumps are annihilated and all the ingredients are well mixed.

In a large bowl, combine the egg yolks, coconut milk, pumpkin purée, vanilla and cider vinegar. Whisk until combined, then slowly whisk in the melted coconut oil.

In another bowl (holy bowls Batman!), beat the egg whites with an electric mixer (with whisk attachment) until stiff peaks form.

Dump the dry ingredients into the wet and mix. Fold in the egg whites. Keep folding until everything is well mixed.

Spoon onto waffle maker and remove when done.
