Instructions

Step 1: Preheat your oven to 350°F. Grease and line an 8x8-inch baking pan with parchment paper, leaving an overhang for easy removal.
Step 2: In a medium saucepan over low heat, melt 1 cup unsalted butter and 8 oz semisweet chocolate chips together, stirring until smooth and glossy. Remove from heat and whisk in 1 1/4 cups granulated sugar and 1/4 cup brown sugar until combined.
Step 3: Add 3 large eggs one at a time, whisking well after each addition, then stir in 2 tsp vanilla extract.
Step 4: Sift together 1 cup all-purpose flour and 1/2 cup unsweetened cocoa powder in a separate bowl. Gradually fold the dry ingredients into the chocolate mixture until just combined.
Step 5: Stir in 1/2 cup stout beer gently until the batter is smooth and thick.
Step 6: Pour the batter into the prepared pan and smooth the surface with a spatula. Sprinkle 1 tsp sea salt flakes evenly over the top.
Step 7: Bake for 30-35 minutes until the edges are set and a toothpick inserted in the center comes out with moist crumbs. Cool completely in the pan before cutting into bars.
