01 - Preheat oven to 350°F. Line an 8x8 inch square baking pan with parchment paper, leaving overhang on two sides for easy removal.
02 - Combine butter and dark chocolate in a heatproof bowl set over simmering water. Stir gently until completely smooth, then remove from heat and let cool for 5 minutes.
03 - Whisk sugar into the melted chocolate mixture until well blended. Add eggs one at a time, beating thoroughly after each addition. Stir in vanilla extract.
04 - Sift flour, cocoa powder, and salt directly into the batter. Fold gently with a spatula until just combined, being careful not to overmix.
05 - Pour batter into the prepared pan and smooth the top with a spatula. Bake for 20 to 25 minutes until a toothpick inserted in the center comes out with a few moist crumbs clinging to it.
06 - Let brownies cool completely in the pan on a wire rack. Do not rush this step, as the strawberry layer requires a firm base.
07 - Place strawberry halves cut side down in a single even layer across the entire surface of the cooled brownies, pressing lightly to adhere.
08 - Melt semi-sweet chocolate chips with coconut oil using a double boiler or microwave in 30-second intervals, stirring between each until glossy and smooth.
09 - Pour melted chocolate evenly over the strawberry layer. Spread with an offset spatula to ensure all fruit is completely covered.
10 - Refrigerate for 20 to 30 minutes until chocolate is fully set. Lift brownies from the pan using the parchment overhang and slice into 12 squares with a sharp knife, wiping the blade clean between cuts.
