1. Preheat oven to 350 degrees. Mix the brownies according to box directions. Then in an 8×8 baking dish lined with parchment or nonstick spray, pour 1/2 brownie mix on the bottom of the baking dish.

2. For the caramel layer, pour the caramels and the can of sweetened condensed milk in a pot on low to medium heat. Stir occasionally until combined, melted and smooth.

3. Pour the caramel mixture over the top of the bottom brownie mix layer. You will not need to use all the caramel so you can store in the fridge to have later.

4. Sprinkle some of the flaky sea salt over the caramel, if desired. Then pour the remaining brownie mix over the caramel layer.

5. Bake for 35-40 minutes. Ovens vary so check towards the end of baking with a toothpick to see if they are done or need more time.

6. Let cool completely to set and then cut and enjoy!
