• To succeed in making these brownies, follow these detailed steps.

Step 1: Preheat the Oven

• Start by preheating your oven to 350°F (175°C). This is crucial for achieving that perfect texture when baking.

Step 2: Prepare the Baking Dish

• While your oven works its magic, take an 8×8 baking dish and grease it lightly. This ensures your brownies will come out cleanly and won’t stick.

Step 3: Beat the Eggs and Sugar

• In a large mixing bowl, whisk together the eggs and granulated sugar. You want to mix until everything is well combined and slightly fluffy. This step is vital for incorporating air into the mixture, resulting in a nice texture.

Step 4: Add Oil and Vanilla

• Pour in the neutral oil and add the pure vanilla extract. Blend it with the egg-sugar mixture until smooth. This is where the magic begins; the aroma of vanilla becomes tantalizing, filling your kitchen.

Step 5: Combine Dry Ingredients

• In a separate bowl, sift together the cocoa powder, all-purpose flour, espresso powder, fine sea salt, and baking powder. Sifting helps to eliminate lumps and ensures even distribution of the dry ingredients.

Step 6: Mix Dry Ingredients into Wet Ingredients

• Gradually add your dry mixture to the wet ingredients. Stir gently until it’s just combined. Avoid overmixing; we are aiming for that fudgy brownie texture!

Step 7: Stir in Chocolate Chips and Nuts

• Next, fold in the mini chocolate chips and chopped walnuts or pecans. These add texture and a burst of flavor. You can add more chocolate chips if you’re feeling indulgent!

Step 8: Pour into the Baking Dish

• Pour the batter into your prepared baking dish. Use a spatula to spread it evenly. This ensures uniform baking and a nice texture throughout.

Step 9: Bake

• Place your baking dish into the preheated oven and bake for about 25-30 minutes. To check for doneness, insert a toothpick in the center. It should come out with a few moist crumbs, indicating the brownies are perfectly baked.

Step 10: Cool and Serve

• Once done, take your brownies out of the oven and allow them to cool in the dish for about 10-15 minutes. After that, transfer them to a wire rack to cool completely. Cut them into squares and enjoy your delicious adventure in baking!
