Step 1: Preheat your oven to 350°F (175°C) to ensure even baking.
Step 2: Line a baking sheet with parchment paper to prevent sticking.
Step 3: Melt the unsalted butter in a microwave-safe bowl and let it cool slightly.
Step 4: In a large mixing bowl, combine the brownie mix, melted butter, and eggs. Stir until well combined.
Step 5: Chop the soft caramel squares and gently fold them into the brownie mixture.
Step 6: Drop rounded balls of dough onto the prepared baking sheet, leaving space between each.
Step 7: Sprinkle a pinch of coarse sea salt on top of each cookie before baking.
Step 8: Bake for 12-15 minutes, until the edges are set but the centers remain soft.
Step 9: Cool the cookies on the baking sheet for a few minutes before transferring to a wire rack.
