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, stirring gently until completely smooth. Remove from heat and allow to cool slightly for about 5 minutes.
03 - Whisk in the granulated sugar 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 wet mixture. 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 attached.
06 - Let the brownies cool completely in the pan on a wire rack, approximately 30 to 45 minutes.
07 - Place the strawberry halves cut side down in a single, even layer across the entire surface of the cooled brownies, pressing them gently so they adhere.
08 - Melt the semi-sweet chocolate chips and coconut oil together in the microwave using 30-second intervals, stirring between each burst, until glossy and smooth. Alternatively, use a double boiler.
09 - Pour the melted chocolate evenly over the strawberry layer. Use an offset spatula to spread it, ensuring all the fruit is completely covered.
10 - Place the pan in the refrigerator 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 paper overhang. Slice into 12 squares with a sharp knife, wiping the blade clean between each cut for neat edges.
