Prep Time: 10 minutes
Cook Time: ~30 minutes
Total Time: ~40 minutes

Ingredients
- ¾ cup (170 g) unsalted butter
- 4 oz (113 g) semi-sweet chocolate bar, finely chopped
- 2 cups (400 g) granulated sugar
- 3 large eggs, room temperature
- 2 teaspoons vanilla extract
- 1 cup (82 g) unsweetened cocoa powder
- 1 cup (125 g) all-purpose flour (spooned & leveled)
- 1 teaspoon salt
- Optional: 1¼ cups (225 g) semi-sweet chocolate chips
Instructions
➜ Preheat oven to 350°F and line a 9×13-inch baking pan with parchment paper, leaving an overhang for easy removal.
➜ In a microwave-safe bowl or over a double-boiler, melt butter and chopped chocolate together, stirring until smooth.
➜ Quickly whisk in the sugar. The mixture will be glossy and thick.
➜ Add eggs one at a time, stirring after each until the batter is smooth and thick. Stir in vanilla.
➜ Sift in cocoa powder, flour and salt. Fold in gently until just combined. Do not overmix. If using, fold in chocolate chips now.
➜ Spread the batter evenly into the prepared pan and bake for about 30 minutes. To test doneness, insert a toothpick into the center. The brownies are ready when a few moist crumbs remain on the toothpick (not wet batter).
➜ Let the brownies cool completely in the pan before lifting out via the parchment overhang and cutting into squares.
Pro Tips (FAQ-Style)
How do I get those shiny crackly tops?
Whisk the sugar into the warm butter-chocolate mixture right after melting—this helps form the glossy top.
Can I freeze these brownies?
Yes—once cooled, wrap tightly and freeze up to 3 months. Thaw in the fridge and bring to room temperature before serving.
Why are these brownies so fudgy?
Because they use minimal flour, no leavening agents, and rely on eggs and cocoa for structure which yields dense, rich texture.
