Ingredients
Scale
- 1 cup (16 tbsp; 226g) unsalted butter, sliced into 16 tbsp-size pieces
- 4 ounces (113g) semi-sweet chocolate, coarsely chopped
- 1 and 1/2 cups (300g) granulated sugar
- 1/2 cup (100g) light brown sugar
- 4 large eggs + 1 egg yolk, at room temperature
- 2 tablespoons (28g/30ml) vegetable oil
- 1 tablespoon pure vanilla extract
- 1 and 1/4 cups (156g) all-purpose flour (spooned & leveled)
- 1 and 1/4 cups (105g) unsweetened dutch-process cocoa powder
- 1 teaspoon salt
- 1 and 2/3 cups (300g) semi-sweet chocolate chips
Instructions
- Preheat the oven to 350°F (177°C) and line a 9×13-inch metal baking pan with parchment paper, leaving an overhang for easy lifting of the brownies.
- In a microwave-safe bowl, combine the butter and chopped chocolate. Melt in 30-second intervals, stirring until fully melted and smooth. Allow to cool slightly.
- In a large mixing bowl, blend granulated sugar, light brown sugar, and eggs using a mixer on medium-high speed until pale, about 4 minutes.
- Pour the warm chocolate mixture into the sugar and egg blend, add vegetable oil and vanilla, then mix until combined.
- Sift flour, cocoa powder, and salt into the batter, then stir in the chocolate chips until fully combined. Spread the thick batter evenly in the prepared pan.
- Bake for 30 minutes. Test doneness with a toothpick; if wet batter sticks, return to the oven for 2 additional minutes. Aim for a toothpick with moist crumbs to avoid over-baking.
- Once baked, cool the brownies in the pan on a cooling rack. Use the parchment overhang to lift them out and cut into squares once cool.
- Store any leftovers covered at room temperature for up to one week.
Notes
Use high-quality chocolate for richer flavor.
For added texture, sprinkle extra chocolate chips on top before baking.
Store in an airtight container for longer freshness.
