Preheat oven to 200 degrees, or 180 fan-forced.
Toast the flaked almonds in a dry pan until golden.
Rinse and core the apples, leaving a generous space in the centre of each one.
Place the cored apples in a baking tray.
Combine the butter with 2 tablespoons of brown sugar, ½ teaspoon cinnamon and a few sultanas.
Fold the flaked almonds into this mixture.
Fill the centre of the apples with the almond mixture.
Optional: Pour a small amount of orange or lemon juice over the apples.
Bake for approx. 25 min, until the apple skins burst and turn golden.
Cool slightly and serve with a scoop of vanilla ice-cream.
