Ingredients

The following ingredients have 9 Servings
  • 1 stick (4 oz) unsalted butter (plus more for buttering the pan)
  • 2 ounces unsweetened chocolate
  • 1 cup granulated sugar
  • 2 large eggs (lightly beaten)
  • 1/2 teaspoon vanilla extract
  • 1/4 cup all-purpose flour
  • 1/4 teaspoon salt
  • 1 cup roughly chopped walnuts ((optional))

Instruction

  • Preheat the oven to 325°F (160°C). Butter an 8-inch square baking pan. Line the pan with parchment paper and butter the paper.
  • Melt the butter and chocolate together in a large saucepan over low heat, stirring constantly, until combined.
  • Remove the pan from the heat and stir in the sugar. Add the eggs and vanilla and stir to make a smooth batter. Add the flour, salt, and walnuts and stir until incorporated.
  • Pour the batter into the prepared baking pan and spread evenly. Bake until a toothpick inserted in the center comes out clean, 40 to 45 minutes. Let cool on a rack. Cut into squares and serve.
