Prep 20 min Cook 30 min Serves 9 Source

Ingredients

  • 1 1/2 sticks (170 grams) unsalted butter
  • 2 tablespoons (27 grams) vegetable oil
  • 1 cup (170 grams) bittersweet chocolate, (chopped)
  • 1 cup plus 2 tablespoons (225 grams) granulated sugar
  • 3 large eggs plus 1 egg yolk, (cold)
  • 1 1/2 teaspoons vanilla extract
  • 2/3 cup (57 grams) Dutch-process cocoa powder, (measured correctly)
  • 1/2 cup (64 grams) bread flour, (measured correctly)
  • 1/2 teaspoon instant espresso powder
  • 1/4 teaspoon fine sea salt

Steps

  1. 1

    Preheat oven to 350 degrees Line a light-colored metal 8-inch square pan with parchment paper, leaving an overhang. Spray with nonstick cooking spray.

  2. 2

    In a large microwave-safe bowl, combine the chocolate, butter, and oil. Microwave in 30-second bursts, stirring between each burst, until the mixture is completely melted and smooth. Add the sugar to the hot butter mixture and whisk vigorously until combined. Allow to cool until just barely warm.

  3. 3

    Add in eggs, yolk, and vanilla extract and whisk vigorously for 1 minute. This helps create that shiny crust on top.

  4. 4

    Use a rubber spatula to stir in the cocoa, flour, espresso powder, and salt until combined. Scrape down the sides and bottom of the bowl to ensure it’s all well combined.

  5. 5

    Pour the batter into the prepared baking pan. Bake until a tester comes out with moist crumbs still attached, about 30 minutes. The internal temperature should be 195° F. Do not overbake.

  6. 6

    Let cool completely to room temperature. If they’re still warm from the oven they will be more cakey. Store in an airtight container at room temperature for up to 3 days or in the fridge for up to 1 week. They're even fudgier when served chilled!
