Combine the flour, baking powder and salt in a mixing bowl. In another bowl beat the chocolate, egg yolks and vanilla lightly. Beat the milk and 1/2 cup of the butter into the egg mixture. Fold the flour mixture into the egg mixture. Stir until combined yet still slightly lumpy. In a small bowl, beat the egg whites until stiff peaks form. Gently fold the egg whites into the batter, leaving little fluffs of egg whites. Pour 1 cup batter onto grids of a preheated, lightly greased waffle iron (grease the waffle iron with 2 tablespoons of the butter, in all). Close the lid quickly: do not open during baking. Bake according to the manufacturer's directions. Melt the remaining butter in a skillet over medium heat. Add the sugar, stirring constantly until it dissolves, about 1 minute. Add the raspberries and cook, stirring, for 2 to 3 minutes. Remove from the heat and add the Grand Marnier. Flame the liquor and continue to cook for 1 minute. Serve the waffles with the raspberry syrup and sweetened whipped cream. Garnish with confectioners'sugar.
