In a mixing bowl, add rolled oats, almond milk, chia seeds, and a pinch of salt. Stir gently until all ingredients are thoroughly mixed. Let it sit for about 5 minutes to hydrate.

Fold in the diced apples into the oat mixture using a spatula for even distribution.

Spoon the oat and apple mixture into a jar, filling it halfway. Drizzle caramel sauce over the oats.

Sprinkle chopped walnuts and ground cinnamon over the caramel layer.

Cover the jar securely and refrigerate overnight or for at least 4 hours.

When ready to enjoy, remove from the refrigerator and serve chilled or at room temperature. Drizzle with additional caramel sauce and sprinkle with cinnamon before serving.
