Step 1

Preheat oven to 325°F. Prepare an 8x8-inch baking pan by lightly greasing, spraying with nonstick cooking spray, or lining with parchment paper.

Step 2

In a medium bowl, combine brownie mix, water, oil and egg and mix until well combined.

Step 3

Spoon half the batter into the prepared pan and smooth into an even layer. Unwrap the chocolate squares and place them directly onto the brownie batter. You don’t have to use all of them, but I typically put them into the pan pretty tightly. Spoon the remaining batter over the chocolate squares and again, spread the batter evenly to cover the chocolate squares.

Step 4

Bake in preheated oven for 39-40 minutes.

Step 5

Remove pan from oven and lightly sprinkle the brownies with flaky sea salt.

Step 6

Allow the brownies to cool for 15-20 minutes before serving.
