01 - Preheat oven to 350°F. Line a 9x9 inch baking pan with parchment paper, leaving overhang on two sides for easy removal.
02 - Combine butter and 1 cup semisweet chocolate chips in a microwave-safe bowl. Microwave in 30-second intervals, stirring between each, until completely smooth.
03 - Whisk granulated sugar and brown sugar into the melted chocolate until blended. Beat in eggs one at a time, then stir in vanilla extract until incorporated.
04 - Fold in flour and salt, stirring until just combined. Do not overmix. Spread batter evenly across the prepared pan.
05 - Bake for 25–30 minutes until a toothpick inserted in the center comes out with moist crumbs. Let cool completely in the pan.
06 - Arrange strawberry slices in a single even layer over the cooled brownie surface, covering it completely.
07 - Melt remaining 1 cup semisweet chocolate chips with coconut oil in a microwave-safe bowl, stirring until smooth and glossy.
08 - Pour melted chocolate evenly over the strawberry layer, gently tilting the pan to coat all fruit. Refrigerate at least 30 minutes until chocolate is fully set.
09 - Lift brownies from pan using parchment overhang. Slice into 12 squares and serve.
