Prepare the Brownie Base:Preheat oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving some overhang for easy lifting.In a large microwave-safe bowl, melt the butter. Whisk in the sugar until combined. Add eggs and vanilla, whisking until the mixture is smooth.In another bowl, sift together flour, cocoa powder, salt, and baking powder. Gradually add the dry ingredients to the wet, mixing until just combined.Spread the batter evenly into the prepared pan. Bake for 25–30 minutes or until a toothpick inserted comes out with moist crumbs. Let the brownies cool completely in the pan.
Add the Strawberry Layer:Once the brownies are cooled, arrange the halved strawberries cut-side down in an even layer over the top.
Make the Ganache:In a microwave-safe bowl, combine the chocolate chips and heavy cream. Microwave in 30-second intervals, stirring between each, until smooth and glossy.
Assemble and Chill:Pour the ganache over the strawberries, using a spatula to spread it evenly. Chill the pan in the fridge for at least 1 hour or until the ganache is set.Once set, lift the brownies out using the parchment paper, cut into squares, and serve.
