A classic recipe for Belgian waffles calls for 1 cup of warm water, 3 cups of all-purpose flour, 1 cup of whole milk, 1 1/2 teaspoons of active dry yeast and 1 stick of melted unsalted butter. Other ingredients include 2 large eggs, 1/2 teaspoon vanilla extract and confectioner's sugar.
Begin by preheating the oven to 225 degrees Fahrenheit. Dissolve the yeast in small bowl filled with water. Combine the flour and salt in a large bowl. Add the yeast to the flour and salt along with the milk, melted butter, egg yolks and vanilla. Whisk until smooth. Beat the egg whites in a medium bowl until they form soft peaks. Fold them into the batter, and leave for 20 minutes.
Heat and grease the waffle iron, and pour 1 1/4 cups of the batter into it at a time. Cook until the waffles appear golden, then put them into the oven to keep them warm until all waffles are done. After the waffles are done, dust them with confectioners' sugar, and serve with Belgian chocolate fudge sauce.
The Belgian chocolate fudge sauce requires 1 cup of heavy cream, 10 ounces of bittersweet chocolate, chopped and 2 tablespoons of confectioners' sugar. Bring the cream to a boil in a saucepan, then remove it from the heat. Add the chocolate, wait for two minutes, then stir until the chocolate melts. Add the sugar, and whisk until the sauce becomes smooth.
