01 - Preheat the 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 melted and smooth, then remove from heat and let cool for 5 minutes.
03 - Add the sugar to the melted chocolate mixture and stir until well blended. Beat in the eggs one at a time, mixing 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 to 25 minutes, or until a toothpick inserted in 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 proceed until the base is fully cooled to room temperature.
07 - Place the strawberry halves cut side down in a single even layer across the entire surface of the cooled brownie base.
08 - Melt the semi-sweet chocolate chips with coconut oil in a microwave-safe bowl, heating in 30-second bursts and stirring between intervals, until glossy and smooth. Alternatively, use a double boiler.
09 - Pour the melted chocolate evenly over the strawberry layer. Spread with an offset spatula to ensure all strawberries are completely covered.
10 - Refrigerate the pan for 20 to 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.
