Preheat & Prep: Preheat the oven to 350°F (175°C). Grease an 8x8-inch baking pan or line it with parchment paper.
Make the Brownie Batter: In a mixing bowl, whisk together melted butter and sugar. Add eggs and vanilla, mixing until smooth. Stir in cocoa powder, flour, salt, and baking powder until combined.
Bake the Brownies: Pour the batter into the prepared pan and spread evenly. Bake for 30-35 minutes or until a toothpick inserted in the center comes out with a few moist crumbs. Let it cool completely.
Add the Strawberry Layer: Arrange fresh strawberry slices evenly over the cooled brownies.
Prepare the Chocolate Ganache: In a small saucepan, heat heavy cream until just simmering (do not boil). Pour over the chocolate chips in a bowl and let sit for 2 minutes. Stir until smooth.
Assemble & Chill: Pour the ganache over the strawberries and spread evenly. Refrigerate for at least 1 hour or until the ganache is set.
Slice & Serve: Cut into squares and enjoy!
