Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking pan or line it with parchment paper for easy removal.

In a large mixing bowl, combine the melted butter and granulated sugar. Whisk until well combined.

Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

In another bowl, whisk together the flour, cocoa powder, salt, and baking powder.

Gradually add the dry ingredients to the wet mixture, stirring until just combined. Be careful not to overmix.

Pour the brownie batter into the prepared baking pan and spread it evenly.

Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.

Allow the brownies to cool completely in the pan on a wire rack.

Once cooled, cut the brownies into squares. To serve, place a brownie on a plate, top with sliced strawberries, and add a generous dollop of whipped cream.
