Expert Baking Tips
- Baking Pan: Line your 8x8-inch baking pan with parchment paper, creating "handles" that hang over the sides. Then grease your pan with non-stick spray. This makes extracting the brownies once they have cooled extremely easy.
- Measuring Flour: To help ensure you don’t add extra flour, follow these three simple steps: 1) Fluff up the flour using a fork. 2) Spoon the flour into your measuring cup. 3) Scrape a knife across the top of the measuring cup to level out the flour.
- Folding: This means we carefully combine our ingredients without stirring or beating. We do this with a silicone spatula until the ingredients are just combined with each other, “folding” everything together.
- Bake Time: The brownies will take anywhere from 30-35 minutes to bake. When using a toothpick to test the center, it should come out with a few moist crumbs. If super wet, then they need more time to bake.
- Cooling: To easily cut and serve the brownies, allow them to cool for at least one hour. I like to use a dough scraper to get smooth and even cuts.
Here are some notes on the ingredients we'll be using. For the full ingredients list, look at the recipe card below.
- Chocolate: I used a bittersweet chocolate bar (Ghirardelli and Scharffen Berger are my favorite) but you could also use semi-sweet or milk chocolate.
- Eggs: A combination of two large eggs and one egg yolk at room temperature are needed. That extra yolk helps to make the brownies chewy and thick.
- Oil: Just a little bit of vegetable oil added to the batter will help to intensify the chocolate flavor, along with adding extra fudginess.
- Flour: I used all purpose flour. Be sure to properly measure your flour (check out "Expert Baking Tips" above). Do not directly scoop the flour out with a measuing cup.
- Cocoa Powder: I used Hershey's dark chocolate cocoa powder, but you could also substitute it with regular cocoa powder.
Here are the step by step instructions on how to make this dark chocolate brownie recipe.
Step 1: Melt the chocolate. In a medium or small saucepan over medium heat, melt the butter and chocolate, mixing occasionally, until completely melted and smooth. Set aside.
Step 2: Wet ingredients. In a large bowl, whisk together the white sugar, eggs, and egg yolk for 3 minutes. Then whisk in the oil, vanilla extract, and melted chocolate mixture, just until combined.
Step 3: Dry ingredients: Gently fold in the flour, sifted cocoa powder, and salt using a silicone spatula. Pour batter into the prepared square pan.
Step 4: Bake. Bake the brownies for 30-35 minutes, or just until the edges are set and the middle of the brownies no longer jiggle.
Keep any leftover brownies in an airtight container on the counter for up to 5 days.
