For the Fudge Frosting

  • Dark chocolate: Forms the base of the frosting. For the best flavor, use a good-quality bar.
  • Heavy cream: Adds richness and helps the chocolate melt smoothly.
  • Unsalted butter: Don’t sub in salted butter for this recipe. Sometimes you can get away with it, but not here.

  • Vanilla extract: Use the real stuff, please. No imitation vanilla allowed!

Preheat the oven to 350°F and prepare a 9-inch round baking pan by greasing it with butter or misting it with non-stick spray and lining it with a parchment paper round.  Set aside. 

Step 1: Make the Fudge Frosting

Combine the chopped chocolate, heavy cream, butter, and vanilla in a skillet. Sift the powdered sugar over the top to prevent lumps.

Pour the batter into the prepared pan and bake for 22 to 27 minutes, or until a toothpick comes out with a few moist crumbs.

Cool the cake in the pan on a wire rack.

Step 3: Assemble the Cake

Once the cake is completely cool, remove it from the pan and place it on your serving plate.

The fudge frosting should be thick but easy to spread. Generously cover the top and sides of the cake.

Tips For Success

  • Use dark chocolate in the chocolate fudge frosting. The addition of powdered sugar gives it plenty of sweetness while keeping the flavor rich and decadent.
  • Use a sifter for the powdered sugar in the frosting to have the silkiest, lump-free fudge frosting.
  • Sift the cocoa powder into the dry ingredients to remove any clumps and achieve a smooth, even cake batter.
  • Be careful not to over-bake the cake. It is done when a toothpick comes out with just a few moist crumbs.
  • For extra fudginess, chill the frosting a bit before spreading it.
  • If needed, use a serrated knife to level the cake before adding the frosting.
  • This cake tastes best at room temperature, so avoid serving it cold.
