Whisk the ingredients together in a large mixing bowl (using an electric mixer or hand whisk) until smooth. Add the oil last , then rest the batter for 10-15 minutes, if time allows.
Heat the waffle maker. When it’s hot, add the batter and seal. Cook the waffles until they are golden and crispy, following the machine instruction. It should take 3-5 minutes per waffle, depending on your machine.
Transfer the waffle to a plate, then make 1-3 more waffles (depending on the size of your machine).
Serve the waffles with lemon and sugar/honey/maple syrup or other toppings.
