Preheat the Oven:

Preheat your 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 the melted butter and sugar until combined. Add the eggs and vanilla extract, mixing until smooth.

Add Dry Ingredients:

Sift in the flour, cocoa powder, and salt. Gently mix until just combined. Fold in chocolate chips if using.

Bake:

Pour the batter into the prepared baking pan, spreading it evenly with a spatula. Bake for 22–25 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. Let the brownies cool completely in the pan.

Prepare the Ganache:

Heat the heavy cream in a small saucepan or microwave until just simmering (do not boil). Pour the hot cream over the chocolate chips in a bowl. Let sit for 2 minutes, then stir until smooth and glossy.

Top with Ganache:

Pour the chocolate ganache over the cooled brownies, spreading it evenly with a spatula. Allow the ganache to set for about 1 hour at room temperature or 30 minutes in the fridge.

Slice and Serve:

Once set, slice into 12 squares and serve. Enjoy the rich and fudgy brownies with the silky ganache topping!
