Mix the ingredients well and let it rest for about 10 minutes.
Heat your waffle maker. If the batter is too thick, add more milk (it should be pourable but thicker than normal pancake batter).
Spray some oil over the hotplates then spoon some batter into the lower one, letting it spread out evenly. Close the maker and cook for 3-5 minutes (depending on your machine). When the waffle is golden, move it to a plate and repeat the cooking. You should be able to make about 4 waffles, depending on your maker.
Serve warm with your chosen toppings.
