World's Best Fudgy Brownies (Printer-Friendly Version)

Rich, fudgy brownies with crackly tops, chewy edges, and intense chocolate flavor for a perfect homemade treat.

# Ingredients Needed:

→ Fats and Oils

01 - 1/2 cup unsalted butter, melted
02 - 1/4 cup vegetable oil

→ Sugars

03 - 1 cup granulated sugar
04 - 2/3 cup powdered sugar

→ Eggs and Flavoring

05 - 3 large eggs
06 - 1 additional egg yolk
07 - 1 teaspoon vanilla extract

→ Chocolate Components

08 - 4 oz bittersweet dark chocolate, chopped
09 - 1/2 cup semi-sweet chocolate chips or chunks
10 - 2 tablespoons Dutch-process cocoa powder

→ Dry Ingredients

11 - 1/2 cup all-purpose flour
12 - 3 tablespoons cornstarch
13 - 1/4 teaspoon espresso powder
14 - 1/4 teaspoon salt

→ Optional Mix-ins

15 - 1/2 cup chopped toasted walnuts or pecans

# Step-by-Step Directions:

01 - Preheat the oven to 350°F (177°C). Line an 8×8-inch baking pan with parchment paper, ensuring an overhang for easy removal.
02 - In a microwave-safe bowl, combine the melted butter, vegetable oil, and chopped bittersweet chocolate. Heat in 30-second intervals, stirring until smooth.
03 - Add espresso powder and Dutch-process cocoa powder to the melted mixture. Whisk thoroughly to bloom the cocoa and deepen chocolate flavor. Set aside to cool slightly.
04 - In a separate large bowl, whisk together powdered sugar, granulated sugar, and vanilla extract until the mixture becomes thick, glossy, and lighter in color, approximately 3 to 6 minutes.
05 - Gradually stir the cooled chocolate mixture into the sugar and egg mixture until fully incorporated.
06 - Sift in the all-purpose flour, cornstarch, salt, and gently fold them into the batter with a rubber spatula, taking care not to overmix.
07 - Fold in semi-sweet chocolate chips and nuts, if desired, evenly distributing them throughout the batter.
08 - Pour the batter into the prepared pan, smoothing the surface. Bake for about 25 minutes, checking around 23 minutes; the edges should be set and a toothpick inserted centrally should come out with moist crumbs.
09 - Allow brownies to cool completely before slicing. For cleaner cuts, chill in refrigerator briefly and wipe knife between slices.

# Helpful Hints:

01 - Avoid overbaking to maintain a fudgy center; the brownies should remain slightly gooey when removed from oven.
02 - Use high-quality chocolate for the richest flavor and weigh flour for precision.
03 - Mix sugars and eggs well to achieve the signature shiny, crackly top.
