Preheat your oven to 350°F (175°C). Preheating ensures that the oven is at the right temperature for baking.
Grease a 9x13-inch (23x33 cm) baking pan to prevent the brownies from sticking. Line the pan with parchment paper, leaving some overhang on the sides. This overhang will make it easy to lift the brownies out later.
In a microwave-safe bowl, place 1 cup of butter. Melt the butter in the microwave in short 20-30 second intervals, stirring each time until it's completely melted. This method helps prevent overheating.
Add the granulated sugar to the melted butter and stir until they are well combined. The sugar will dissolve into the butter.
Incorporate the eggs and vanilla extract into the mixture, ensuring that the batter becomes smooth and uniform in texture.
In a separate bowl, whisk together the flour, cocoa powder, and salt. This step combines the dry ingredients and ensures even distribution.
Gradually add the dry ingredient mixture to the wet ingredients, mixing until they are just combined. Be cautious not to overmix, as overmixing can affect the texture of the brownies.
Pour the brownie batter into the prepared baking pan and use a spatula to evenly spread it out. This ensures that the brownies bake uniformly.
Place the baking pan with the brownie batter in the preheated oven. Bake for 25-30 minutes or until a toothpick inserted into the center comes out with a few moist crumbs. This toothpick test helps determine if the brownies are done.
Once done, remove the brownies from the oven and allow them to cool in the pan for approximately 10 minutes. This cooling period sets the brownies and makes them easier to handle.
In a microwave-safe bowl, combine semisweet chocolate chips, 2 tablespoons of butter, and heavy cream. Microwave in short 20-30 second intervals, stirring each time until the mixture is smooth and the chocolate is fully melted.
Add powdered sugar and vanilla extract to the melted chocolate mixture. Stir until the glaze becomes glossy and thoroughly mixed.
While the brownies are still slightly warm, pour the prepared chocolate glaze over them in the pan. The warmth of the brownies helps the glaze spread evenly.
Use an offset spatula or the back of a spoon to distribute the glaze evenly across the surface of the brownies. This step ensures that every bite is coated with delicious chocolate glaze.
Allow the brownies to cool completely in the pan. This cooling time helps the glaze set.
Once the brownies are fully cooled, use the parchment paper overhangs to lift them out of the pan with ease.
Cut the brownies into squares. You can customize the size of the squares to your preference.
