Ingredients

  • 1 cup all-purpose flour
  • 1 cup granulated sugar
  • 0.5 teaspoon baking soda
  • 0.5 teaspoon salt
  • 1 cup whole milk
  • 8 ounces bittersweet chocolate, finely chopped
  • 0.5 cup Dutch-processed cocoa powder
  • 0.5 cup vegetable oil
  • 4 pieces eggs
  • 1 teaspoon vanilla extract
  • 16 ounces milk chocolate, finely chopped
  • 0.5 cup heavy cream
  • 16 tablespoons unsalted butter, cut into pieces and softened

Instructions

  • Preheat your oven to 350°F (175°C).
  • Grease a 13x18-inch rimmed baking sheet with butter or non-stick spray. Optionally, line the bottom with parchment paper.
  • In a large mixing bowl, whisk together the flour, sugar, baking soda, salt, and cocoa powder until well combined.
  • Melt the bittersweet chocolate in a double boiler or microwave-safe bowl. Set aside to cool slightly.
  • In another bowl, whisk together the milk, vegetable oil, eggs, and vanilla extract. Stir in the melted chocolate until smooth.
  • Pour the wet ingredients into the dry ingredients and gently fold together until just combined.
  • Pour the batter into the prepared baking sheet and spread evenly. Bake for 25-30 minutes, or until a toothpick inserted comes out clean.
  • While the cake is cooling, heat the heavy cream in a saucepan until it simmers. Remove from heat and mix in the milk chocolate and butter until smooth.
  • Once the cake has cooled completely, spread the ganache evenly over the top.
