Directions: 1. Preheat to 350ºF. Prepare the 9x9 nonstick baking dish by lining it with parchment paper (this aids in an easier removal when it comes time to serve the brownies). 2. Mix and bake brownies according to recipe on package. Let cool COMPLETELY. 3. Spread the caramel sauce over top. Sprinkle with sea salt. 4. Keep chilled until ready to serve.
If you can bear the wait, let the caramel topping sit on the brownies for a day or even just overnight (covered, of course). It will soak into the brownies a bit, making them even more moist and deliciously gooey than ever!
Note: *Another great option for the caramel topping would be Nestle’s Duce de Leche, which you can usually find beside the sweetened condensed milk or in the Hispanic section of the grocery store.
