I bake all my waffles in special silicone molds in the oven. But if you have a stationary waffle iron, then nothing can stop you from cooking these waffles in it.
Mix all the ingredients in a mixer except for the olive oil. I cook these waffles in silicone molds in the oven. Pour the dough into greased molds and bake at 220°C for 8-9 minutes. (or cook in your waffle iron according to instructions).
Remove the baking sheet with the molds from the oven, turn the waffles out of the mold onto the baking sheet and bake with the raised side up for 4-5 minutes. until they are browned.
