Single Layer Chocolate Fudge Cake

Ingredients

  • 1/2 cup unsalted butter
  • 1/2 cup vegetable oil
  • 1 cup granulated sugar
  • 1/2 cup light brown sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • 3/4 cup buttermilk
  • 1/2 cup hot coffee
  • 1 cup all-purpose flour
  • 1/2 cup cocoa powder
  • 1 tsp baking soda
  • 1/2 tsp baking powder
  • 1/2 tsp salt

Ganache Frosting

Instructions

  • Preheat the oven to 350°F (175°C). Grease and line an 8-inch round cake pan with parchment paper.
  • In a large mixing bowl, whisk together the melted butter, oil, granulated sugar, and brown sugar until smooth.
  • Add the eggs and vanilla extract, whisking until fully combined.
  • Pour in the buttermilk and mix well.
  • Sift in the flour, cocoa powder, baking soda, baking powder, and salt, then mix until just combined.
  • Slowly pour in the hot coffee (or water) while stirring gently until the batter is smooth and glossy. The batter will be thin—this is normal!
  • Pour the batter into the prepared cake pan and bake for 30-35 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
  • Let the cake cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely.

Make the Ganache Frosting

  • Place the chocolate chips in a heatproof bowl.
  • Heat the heavy cream in a small saucepan over medium heat until it just begins to simmer (do not boil).Pour the hot cream over the chocolate and let it sit for 1-2 minutes to soften.
  • Stir gently until the ganache is smooth and glossy. Add the vanilla extract and a pinch of salt, stirring to combine.
  • Let the ganache cool for 10-15 minutes to thicken slightly before frosting the cake.

Assemble the Cake

  • Pour or spread the ganache frosting over the cooled cake, letting it drip over the edges for a decadent look.
  • Slice and enjoy! For an extra indulgent touch, serve with whipped cream or a scoop of vanilla ice cream.
