How to Make It
In a large bowl, whisk the flour with the sugar and salt. In a medium bowl, beat the egg yolks with the water and vanilla. Stir the wet ingredients into the dry ingredients, then stir in the butter until incorporated.
In a medium bowl, using a handheld electric mixer, beat the egg whites at medium-high speed until soft peaks form, about 2 minutes. Fold them into the batter.
Preheat the oven to 200°. Heat a Belgian waffle iron, then grease it with melted butter. Spoon 1 cup of the batter into the iron, close the top and cook until the waffle is golden, 6 minutes. Transfer the waffle the prepared baking sheet and keep warm in the oven. Repeat with the remaining batter. Top the waffles with quartered strawberries and unsweetened whipped cream. Dust with confectioners' sugar and serve.
