01 - Preheat oven to 350°F (175°C). Line a 9×9-inch baking pan with parchment paper, leaving an overhang on two sides for easy removal.
02 - In a microwave-safe bowl, melt the butter with 1 cup of semisweet chocolate chips in 30-second intervals, stirring between each burst, until completely smooth.
03 - Whisk the granulated sugar and brown sugar into the melted chocolate mixture until well blended. Beat in the eggs one at a time, mixing thoroughly after each addition. Stir in the vanilla extract.
04 - Fold in the flour and salt, stirring gently until just combined. Do not overmix. Spread the batter evenly into the prepared baking pan.
05 - Bake for 25 to 30 minutes, or until a toothpick inserted in the center comes out with moist crumbs. Avoid overbaking. Allow the brownies to cool completely in the pan.
06 - Arrange the sliced strawberries in a single, even layer over the cooled brownie base, covering the entire surface.
07 - In a microwave-safe bowl, melt the remaining 1 cup of semisweet chocolate chips with the coconut oil, stirring until the mixture is smooth and glossy.
08 - Pour the melted chocolate evenly over the strawberry layer, gently tilting the pan to ensure full coverage of the fruit. Refrigerate for at least 30 minutes, or until the chocolate topping is firmly set.
09 - Lift the brownies out of the pan using the parchment paper overhang. Slice into 12 even squares and serve.
