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