Ingredients

  • 1 1/2 cups (300g) granulated sugar
  • 3/4 cup + 3 tablespoons (217g) unsalted butter, at room temperature
  • 10.5 oz (300g) dark or semi-sweet chocolate, chopped
  • 1 1/2 teaspoons vanilla extract
  • 1 1/2 tablespoons cold espresso or coffee
  • 3 large eggs, at room temperature
  • 1 cup (120g) all-purpose flour
  • 1 1/2 tablespoons (11g) cocoa powder
  • 1/2 teaspoon salt
  • 2/3 cup (75g) chocolate chips
  • 3/4 cup (75g) pecans, roughly chopped
  • 1 1/2 teaspoons Fleur de sel

Prepare the Batter

Preheat your oven to 350°F and line a 9×13 inch baking pan with foil or parchment paper, leaving an overhang on the sides to easily lift the brownies out later.

In a medium, heatproof bowl set over a saucepan of simmering water (a bain-marie), melt the chopped chocolate. Once it’s smooth, remove it from the heat and set it aside to cool slightly.

In a large mixing bowl, use a stand mixer or hand mixer to cream the room temperature butter and granulated sugar together for ~5 minutes. The mixture should become pale and fluffy.

Add the eggs, one at a time, and continue to whisk for at least another 5 minutes until the mixture is foamy. This step is crucial for creating the crackly top on the brownies.

Switch to a spatula and gently fold in the vanilla extract, cold espresso, and the cooled, melted chocolate. Mix only until just incorporated to avoid deflating the air you’ve whipped in.

Combine and Bake

In a separate bowl, whisk together the all-purpose flour, cocoa powder, and salt.

Fold the dry ingredients into the chocolate mixture until just combined, being careful not to overmix. Then, gently fold in the chocolate chips and chopped pecans.

Pour the batter into the prepared pan and use the spatula to spread it into an even layer.

Sprinkle the fleur de sel evenly over the top of the batter.

Bake for ~40-45 minutes. The edges should look set, but the middle should still be slightly soft.

Transfer the pan to a cooling rack and let the brownies cool for at least 20-30 minutes before lifting them out of the pan and slicing them into squares. This recipe will make ~16-20 brownies depending on how large you cut them.

Brownies with Pecans and Fleur de Sel

These brownies are fudgy and chewy, with pecans for texture and a sprinkle of fleur de sel on top to enhance the chocolate flavor. Getting a shiny, crackly top is a key part of this recipe, which is achieved by whipping the eggs and sugar thoroughly to create a thin meringue-like layer.
