1-First Step: Preparation and Pan Setup Start by preheating your oven to 350°F (175°C). While the oven heats, prepare your baking pan. You’ll need either an 8×4 or 9×5-inch loaf pan. Line the pan with parchment paper, allowing it to overhang on the sides. This parchment “sling” makes it incredibly easy to remove the brownies after baking. If you prefer thicker brownies, use the 8×4 pan; for slightly thinner ones, go with the 9×5. Lightly grease the parchment paper with a little butter or cooking spray to ensure the brownies don’t stick. Preparation time for this step is minimal just about 5 minutes. Having everything ready before you start mixing will make the process smoother and ensure you don’t overmix the batter, which can lead to tough brownies.

2-Second Step: Mixing the Wet Ingredients In a microwave-safe bowl, melt the 6 tablespoons (79 g) of butter. You can also do this on the stovetop in a small saucepan over low heat. Once melted, whisk in both the granulated sugar (½ cup/100 g) and light brown sugar (6 tablespoons/75 g). Continue whisking until the mixture forms a paste-like consistency and pulls away slightly from the sides of the bowl. This step is crucial for developing that signature crackly top on your brownies, so don’t rush it. The sugar-butter mixture should look glossy and somewhat thick. If it seems too hot, let it cool for a minute or two before proceeding to the next step. This prevents the egg from cooking when you add it.

3-Third Step: Adding the Egg and Vanilla Once your sugar and butter mixture has cooled slightly, whisk in the egg and ½ tablespoon of vanilla extract. Whisk vigorously until the mixture is smooth and well combined. You’ll notice the batter becoming glossy and slightly thicker. This is a good sign it means the emulsion is forming properly. For the best results, use a room temperature egg if possible. Room temperature eggs incorporate more easily into the batter, creating a smoother texture. If you’ve forgotten to take the egg out ahead of time, you can place it in a bowl of warm water for 5 minutes to take the chill off.

4-Fourth Step: Incorporating Dry Ingredients Now it’s time to add the dry ingredients. To the bowl, add the 5 tablespoons (40 g) of all-purpose flour, 6 tablespoons (32 g) of unsweetened cocoa powder, and ⅛ teaspoon of salt. Whisk gently until just combined, being careful not to overmix. You want to stop as soon as you no longer see dry spots of flour or cocoa. Overmixing at this stage can develop too much gluten in the flour, resulting in tough, cakey brownies instead of fudgy ones. A few small lumps are okay they’ll disappear during baking. The batter should be thick and glossy, not runny.

5-Fifth Step: Adding Chocolate Chips and Baking If you’re using chocolate chips (and we highly recommend you do!), gently fold in ⅓ cup of chocolate chips. Use a spatula or wooden spoon for this step to avoid breaking the chips or overworking the batter. Spread the batter evenly in your prepared loaf pan, using the spatula to smooth the top. Place the pan in the preheated oven and bake for 26-36 minutes. The baking time will depend on your pan size and oven. Start checking at the 26-minute mark. The brownies are done when the top is crackly, a toothpick inserted into the center comes out with moist crumbs (not wet batter), and there’s no jiggle when you gently shake the pan.

6-Final Step: Cooling and Serving This final step requires patience but is essential for the perfect texture. Allow the brownies to cool completely in the pan on a wire rack before slicing. This cooling period allows the structure to set, ensuring clean cuts and the ideal fudgy texture. This will take about 1-2 hours. Once completely cooled, use the parchment paper overhang to lift the brownies out of the pan. Place them on a cutting board and slice into your desired size. For a 8×4 pan, you’ll get about 6-8 small brownies; for a 9×5 pan, you’ll get about 8-10 slightly smaller ones. Enjoy them at room temperature, or warm slightly in the microwave for 10-15 seconds for that fresh-baked experience.
