These fudgy dark chocolate brownies are extremely decadent, chewy, and rich with dark chocolate flavor. Both dark cocoa powder and a bittersweet chocolate bar are used to create these perfect brownies!
Preheat the oven to 350 degrees and line an 8x8-inch baking pan with parchment paper, creating "handles" that hang over the sides. Then spray with non-stick spray.
In a medium-sized saucepan over medium heat, melt the butter and chocolate, mixing occasionally, until completely melted and smooth. Set aside and allow to cool for 5 minutes.
In a large bowl, whisk together the sugar, eggs, and egg yolk for 3 minutes (this step is crucial). Whisk in the vegetable oil, vanilla extract, and melted chocolate, just until combined.
Gently fold in the flour, sifted cocoa powder, and salt using a silicone spatula.
Spread the brownie mixture into the prepared pan. Use your silicone spatula to spread out the batter evenly. Bake for 30-35 minutes, just until the edges are set and the middle of the brownies doesn't jiggle. You can also use a toothpick to check the center (the toothpick should come out clean with just a few crumbs).
Allow the brownies to completely cool (about 1 hour) before slicing them into bars. Keep any leftover brownies in an airtight container on the counter for up to 5 days.
Notes:
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.
