Peel and chop the apples into small pieces, ensuring they are uniform for even freezing and blending.
Arrange the chopped apples on a baking sheet or plate and freeze until solid, about 2 hours or overnight.
Pour the cooled caramel sauce into the blender, adding the frozen apple chunks on top.
Add the ice cubes to the blender, then secure the lid firmly.
Blend everything on high speed until the mixture is thick, smooth, and scoopable, about 1-2 minutes. You should hear a steady whir and see a creamy, slightly frothy texture forming.
Taste and, if desired, add a bit more caramel sauce for extra sweetness, then give it a quick pulse to combine.
Scoop the thick slushie into glasses, allowing some caramel swirl to cascade down the sides for visual appeal.
Finish with a light drizzle of additional caramel sauce over the top for added richness and presentation.
Serve immediately with a spoon for a creamy, icy treat that’s perfect for hot days or as a nostalgic dessert.
