In a bowl, combine the flour and baking powder. Set aside.
In another bowl, whisk together the ricotta, sugar, eggs and vanilla. Add the dry ingredients and whisk until smooth. Stir in the raisins.
Preheat the waffle iron. With an ice cream scoop, drop about 1/4 cup (60 ml) of batter without spreading it. Add a quarter of the apple slices (4 to 5 thin slices) and top with another 1/4 cup (60 ml) of batter. Close the iron. Cook for 4 to 5 minutes or until the waffles are crisp and golden brown. Keep warm. Repeat with the remaining batter and apple slices.
When ready to serve, top each waffle with ice cream and julienned apple. Dust with icing sugar.
