These dark chocolate brownies are the ultimate treat for anyone who loves a deep, intense cocoa flavor with a perfectly fudgy, dense texture. Using high-quality dark chocolate (at least 70% cacao) instead of milk chocolate or cocoa powder alone gives these brownies a sophisticated, slightly bitter edge that balances the sweetness beautifully. The result is a glossy, crackly-top brownie that’s moist in the center, chewy at the edges, and incredibly simple to make with just one saucepan and a whisk.
Ingredients
- 10 oz (280 g) dark chocolate (70% cacao), roughly chopped
- 1 cup (2 sticks / 226 g) unsalted butter, cut into cubes
- 1 ½ cups (300 g) granulated sugar
- 4 large eggs, at room temperature
- 1 teaspoon vanilla extract
- ¾ cup (95 g) all-purpose flour
- ¼ cup (25 g) unsweetened cocoa powder (Dutch-processed or natural)
- ½ teaspoon salt
- Optional: 1 cup (170 g) dark chocolate chips or chopped walnuts
Instructions
- Preheat your oven to 350°F (175°C). Line an 8-inch (20 cm) square baking pan with parchment paper, leaving some overhang on two sides for easy lifting.
- In a medium saucepan over low heat, melt the chopped dark chocolate and butter together, stirring frequently until smooth. Remove from heat immediately and let cool for 5 minutes.
- Whisk the sugar into the chocolate-butter mixture until fully combined. The mixture will look grainy—that’s normal.
- Add the eggs one at a time, whisking vigorously after each addition until the batter is glossy and well incorporated. Stir in the vanilla extract.
- Sift the flour, cocoa powder, and salt over the batter. Fold gently with a spatula until just a few streaks of flour remain. Do not overmix.
- If using, fold in the chocolate chips or nuts. Pour the batter into the prepared pan and spread it into an even layer.
- Bake for 28–32 minutes, until the top is set and a toothpick inserted into the center comes out with a few moist crumbs (not wet batter). The internal temperature should read about 200°F (93°C) for a fudgy texture—this is not a safety requirement, just a doneness guide.
- Let the brownies cool completely in the pan on a wire rack, about 1 hour, before lifting out and slicing into 16 squares.
Tips
- Use good chocolate: The flavor of these brownies depends almost entirely on the chocolate. Choose a bar you enjoy eating—if it’s too bitter for you, use a 60% cacao bar instead of 70%.
- Don’t overbake: Brownies continue to set as they cool. Pull them out when a toothpick comes out with moist crumbs, not clean, to keep them fudgy. Overbaking yields dry, cakey brownies.
- Room-temperature eggs: Cold eggs can seize the chocolate mixture, making it lumpy. Let your eggs sit out for 30 minutes before starting, or place them in a bowl of warm water for 5 minutes.
- Substitutions: No dark chocolate? Use 1 cup (170 g) semisweet chocolate chips plus 2 tablespoons (30 g) butter. For a gluten-free version, swap the all-purpose flour for a 1:1 gluten-free baking flour blend—the texture will be slightly more tender.
Serving Suggestions
Serve these brownies slightly warm with a scoop of vanilla ice cream and a drizzle of caramel sauce for a classic sundae. For a more elegant dessert, dust them with powdered sugar and serve alongside fresh raspberries, whose tartness cuts through the richness. They also make a fantastic base for an ice cream sandwich—just slice them thinner and sandwich with your favorite flavor.
Variations
- Espresso Brownies: Add 1 tablespoon of instant espresso powder to the melted chocolate mixture for a mocha twist.
- Salted Caramel Swirl: After pouring the batter into the pan, dollop ½ cup (120 ml) of caramel sauce on top and swirl with a knife before baking.
- Peppermint Bark: Fold in ½ cup (85 g) crushed peppermint candies and top with a layer of melted white chocolate after cooling.
- Peanut Butter Swirl: Warm ½ cup (130 g) peanut butter in the microwave for 20 seconds, then dollop over the batter and swirl.
Storage and Reheating
Store leftover brownies in an airtight container at room temperature for up to 4 days, or in the refrigerator for up to a week—chilling makes them even more fudgy. To freeze, wrap individual brownies tightly in plastic wrap and place in a freezer-safe bag for up to 3 months. Thaw at room temperature for 30 minutes, or reheat a single brownie in the microwave for 15–20 seconds to restore that just-baked melt-in-your-mouth texture.
Frequently Asked Questions
Can I use milk chocolate instead of dark? Yes, but reduce the sugar to 1 cup (200 g) because milk chocolate is much sweeter. The texture will be softer and less intense.
Why did my brownies turn out cakey? You likely overmixed the batter after adding the flour, which develops gluten, or you baked them too long. Mix until just combined and pull them out at the 30-minute mark.
Can I make these without a saucepan? Absolutely. Melt the chocolate and butter in a microwave-safe bowl in 30-second bursts, stirring between each, until smooth. Then proceed with the recipe.
How can I get cleaner cuts? Use a sharp chef’s knife and wipe it clean between each cut. For the cleanest edges, chill the brownies in the refrigerator for 30 minutes before slicing.
Can I add eggs one at a time? What if I add them all at once? Adding them one at a time allows each egg to fully emulsify into the chocolate, creating a shiny, crackly top. Adding all at once may result in a less glossy finish, but the brownies will still taste great.
Why are my brownies stuck to the pan? Always line the pan with parchment paper, leaving overhang. If you didn’t, run a knife around the edges while the brownies are still warm, then invert onto a cutting board.
