Preheat the Oven – Preheat your oven to 175°C (350°F). Line a 9x9-inch square baking pan with parchment paper or lightly grease it.
Melt the Butter – In a saucepan over low heat, melt the butter. Once melted, remove from heat and stir in the granulated sugar and brown sugar until smooth.
Add the Eggs and Vanilla – Beat in the eggs, one at a time, making sure to stir well after each addition. Add the vanilla extract and mix until combined.
Add the Dry Ingredients – In a separate bowl, whisk together the cocoa powder, flour, salt, and baking powder. Gradually add the dry ingredients to the wet mixture, stirring until just combined. Be careful not to overmix.
Fold in the Chocolate Chips – If using, fold in the chocolate chips to the brownie batter.
Bake the Brownies – Pour the batter into the prepared pan and spread it out evenly. Bake for 20-25 minutes, or until a toothpick inserted into the center comes out with just a few moist crumbs (not wet batter).
Cool and Serve – Let the brownies cool completely in the pan before cutting them into squares and serving. Enjoy!
