Mix the dry ingredients in a large bowl. Using a wooden spoon or electric mixer, beat in the eggs, then then add the milk gradually, whisking until you get a thick, smooth batter. Add more milk if it’s too thick (the batter should be pourable). Add the oil and stir until combined.
Heat the waffle machine. Once it’s hot, spoon in the batter and seal. Follow the machine instructions to cook the waffles, they should be golden brown and crisp on the outside, soft inside.
Serve, dusted with cinnamon sugar or honey, chocolate sauce, compote etc (see above).
