Method
Bake the base
- Preheat the oven to 350F and line a 9x13 pan with parchment for easy lifting.
- Mix all-purpose flour, rolled oats, brown sugar, both sugars, baking soda, and salt, then drizzle in unsalted butter and toss until evenly moistened.
- Press 2/3 of the mixture firmly into the prepared pan, then bake for 10 minutes.
Add caramel and topping
- Whisk caramel sauce and heavy cream until smooth, then pour over the hot base.
- Scatter semi-sweet chocolate chips over the caramel, then crumble the remaining dough on top.
- Bake for 20-22 minutes more, until the topping turns golden.
Finish and slice
- Sprinkle flaky sea salt over the warm bars.
- Cool completely before slicing so the caramel sets cleanly.
Notes
Press the base firmly to prevent gaps so the caramel layer stays contained. Store covered in the refrigerator for up to 5 days; freeze sliced bars in an airtight container for up to 2 months. For a lighter variation, use half as much sugar in the caramel sauce if store-bought, keeping the total caramel amount the same.
