Preheat oven to 350℉ and grease a 9x9 inch baking dish.
Prepare the brownie mix according to the package instructions; stir in 1/2 cup of the pecans.
1 box brownie mix, 1 cup chopped pecans
Pour the brownie batter into the prepared pan and bake as instructions state. Do not overbake - I recommend setting your timer for 5 minutes less than the box says just to be safe!
While the brownies are baking, combine the caramel bits, heavy whipping cream and salt in a microwave-safe bowl.
1 cup caramel bits, 3 tablespoons heavy whipping cream, 1/4 teaspoon salt
Microwave the caramels for 1 minute and stir. Add 15-30 second increments, stirring after each until smooth.
When the brownies come out of the oven, use a fork or the back of a wooden spoon to poke holes all over the brownies. Try not to poke all the way through to the bottom of the pan; just go about 2/3 the way through.
Pour about 3/4 of the caramel sauce over the brownies slowly, giving the sauce time to soak into the holes.
Sprinkle with the pecans and then the chocolate chips.
1/2 cup chopped semi-sweet chocolate bar or chocolate chips
Drizzle the top with the remaining caramel and sprinkle with flaky sea salt if desired.

Let cool then cut into squares.
