Step 1: Preheat your oven to 350°F (175°C) to ensure even baking.
Step 2: Line your 9x9 inch baking pan with parchment paper for easy removal.
Step 3: Melt the salted butter and semisweet chocolate in a medium saucepan over low heat, stirring until smooth. Remove from heat and let cool slightly.
Step 4: In a large mixing bowl, whisk together the granulated sugar and eggs until light and fluffy, about 2-3 minutes.
Step 5: Pour the melted chocolate and butter mixture into the sugar and egg mixture, stirring until well combined.
Step 6: In a separate bowl, sift together the flour, cocoa powder, and baking powder. Gradually fold this dry mixture into the wet ingredients until just combined.
Step 7: Gently fold in the panko breadcrumbs, ensuring they are evenly distributed throughout the batter.
Step 8: Pour the brownie batter into the prepared baking pan and bake for 25-30 minutes, or until a toothpick comes out with a few moist crumbs.
Step 9: Sprinkle flaky sea salt over the brownies immediately after removing them from the oven.
Step 10: Let the brownies cool in the pan for about 10 minutes before transferring to a cooling rack. Once cooled, cut into squares and enjoy!
