Steps

Sift and mix the flour, cornstarch, baking powder, salt and sugar. The starch is not decorative: it lowers the gluten proportion so the waffle stays crisp longer.
⏲ 3 min
Mix the yolks only with the milk, melted butter and vanilla, pour into the dry ingredients and stir just until the lumps go. Beat it longer and gluten develops into toughness.
⏲ 3 min
Whip the whites to medium peaks — just short of stiff. Taken all the way stiff, they clump when folded in and leave white streaks. The bowl and whisk must be free of fat or yolk or they will not whip.
⏲ 5 min
Fold the whites in in three additions, cutting down and lifting over. The first third is sacrificial — loosen the batter roughly with it — and the rest has to keep its air. That air expands as it cooks and hollows the inside, and the hollow structure is the crispness. Whites stirred in whole give you something closer to a pancake.
⏲ 4 min
Rest the batter 20-30 minutes, so the flour hydrates evenly and the gluten relaxes. Some settling of the foam is normal.
⏲ 30 min
Preheat the iron properly. Judge it not by the indicator light but by whether the batter sizzles the instant it lands. The plates hold a lot of heat and need a few minutes beyond the light going out — the same reason ovens do. Brush butter on for the first waffle only.
⏲ 10 min
Pour into the centre and close the lid. Do not overfill trying to reach every corner — about 80% is right, since the whites make it rise.
⏲ 1 min
Do not open the lid until the steam has visibly slowed, usually 4-5 minutes. Opened early, before the structure has set, the waffle tears in half top from bottom, and closing it again does not recover it.
⏲ 5 min
At deep gold, take it out and stand it on a rack. Laid flat on a plate, steam from the underside is trapped and it goes soggy within three minutes. Repeat with the rest of the batter.
⏲ 3 min
Dust with icing sugar at the last moment — dusted early it absorbs moisture and disappears. Serve with whipped cream and fruit.

Tips & Variations

Variations

The Liège waffle is really a different food. Not a thin batter but a stiff, yeast-risen dough studded with pearl sugar. It is irregular in shape, heavy and chewy, and the pearl sugar on the surface melts and caramelises into a hard shell. The chewy waffles sold on Korean streets and in cafés are usually these. It is a yeast-dough project in the way croissants are.
American waffles skip the separated whites and rise on baking powder alone. Thicker and more cake-like, served with maple syrup and butter — essentially the same family as pancake batter.
Savoury works too: cut the sugar to 5g, fold cheese and herbs into the batter, and top with a fried egg or cured ham.
Buttermilk in place of milk gives a softer result, its acid weakening the gluten; swap half the baking powder for bicarbonate of soda if you do.
The thin end of the same batter family is a crepe, and the soak-bread-and-fry end is French toast.

Tips

Separating the whites is what defines the Brussels waffle. Air in the foam expands as it cooks and hollows the interior, and that hollow lets moisture escape so the outside crisps. Skip the step and the texture moves towards pancake (cooking eggs).
Medium peaks, not stiff. Fully stiff whites have no give, break up as you fold, and leave white lumps. And any trace of fat in the bowl stops them whipping at all.
Use the starch. Replacing 20% of the flour with cornstarch lowers the gluten and makes the just-cooked crispness last far longer. An all-flour waffle is leathery within five minutes (choosing flour).
Do not cut the butter. 90g looks like a lot, but that fat is what fries the surface crisp. Reduce it and the waffle also starts sticking to the iron.
Judge the iron by sound, not by the light. It should sizzle the instant the batter lands. The plates hold heat, so they need a few minutes past the indicator going out — the same story as what your oven is doing.
Do not open the lid early. This is the commonest failure. Wait for the steam to slow and it comes out in one piece; open it at three minutes and it tears top from bottom.
Stand them on a rack. Flat on a plate, a waffle wets its own underside. When cooking several, hold the rack in a 200C oven and the last one is as crisp as the first.
Icing sugar last. Dusted early it draws moisture and vanishes.
The batter keeps a day refrigerated, though the foam settles — whip one fresh white into it before cooking and it recovers. Cooked waffles freeze well: cool, freeze, and reheat straight in a toaster for something close to fresh.
