Ingredients
  

  • 1/2 cup unsalted butter cubed
  • 4 oz semi-sweet chocolate chopped
  • 3/4 cup granulated sugar
  • 1/2 cup light brown sugar packed
  • 2 large eggs room temperature
  • 1 tsp vanilla extract
  • 3/4 cup all-purpose flour
  • 1/4 cup unsweetened cocoa powder
  • 1/4 tsp salt

Equipment

  • 1 9-inch round cake pan
  • 2 Mixing bowls
  • 1 Whisk
  • 1 Spatula

Method
 

  1. Preheat oven to 350°F (175°C). Grease and flour a 9-inch round cake pan or line with parchment paper.
  2. In a microwave-safe bowl, melt the chopped semi-sweet chocolate and butter together in 30-second intervals, stirring until smooth.
  3. In a large bowl, whisk together the granulated sugar, brown sugar, and the melted butter/chocolate mixture. Whisk in the eggs one at a time, then the vanilla extract. Beat for one minute until glossy.
  4. In a separate bowl, whisk together the all-purpose flour, unsweetened cocoa powder, and salt.
  5. Gently fold the dry ingredients into the wet ingredients with a spatula until just combined. Do not overmix.
  6. Pour the batter into the prepared pan and spread evenly. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out with moist crumbs.
  7. Let the cake cool in the pan on a wire rack for at least 20-30 minutes before slicing and serving.

Notes

Do Not Overbake: For the fudgiest texture, pull the cake from the oven when it still seems slightly underdone in the center.
Let It Cool: Allowing the cake to cool completely is crucial for it to set properly, ensuring clean cuts and a perfect texture.
