Wash and peel 2 medium-sized apples, then remove the core and cut them into small pieces.
In a blender, add the apple pieces, 500 ml of chilled milk, 2 tablespoons of sugar (adjust according to taste), and a few ice cubes.
Blend the mixture until it becomes smooth and frothy.
Pour the apple milkshake into glasses and serve immediately. You can also garnish with a sprinkle of cinnamon or nutmeg if desired.
