In a mixing bowl or a mason jar, add rolled oats, chia seeds, milk, Greek yogurt, vanilla extract, and a pinch of sea salt. Stir the mixture thoroughly until combined.

Spoon in the caramel sauce into the mixture and gently swirl to combine without overmixing.

Transfer the mixture into an airtight container or mason jar. Seal and refrigerate for at least 4 hours, preferably overnight.

The next morning, stir well and add additional caramel sauce and flaky sea salt if desired. Add your favorite toppings.
