Ultimate Chocolate Mud Cake

Chocolate Mud Cake is a dense, moist cake with a fudgy flavor. It’s similar to a flourless chocolate cake and tastes like a combination of brownies and fudge. Mud cakes are cooked low and slow, which contributes to the tight crumb, delicious consistency, and rich chocolate flavor.

 

Don’t confuse my Australian chocolate mud cake with a Mississippi mud cake; they are both delicious, but this cake is a show-stopper. It’s the perfect cake for birthdays or family get-togethers while elegant enough for fancy dinner parties or special occasions.

This is definitely going to be my next birthday cake, even if I have to make it myself!

I love dark chocolate, and this rich chocolate mud cake is loaded with chocolate flavor that will satisfy your chocolate cravings.

Ingredients to make Australian Chocolate Mud Cake

Gather the ingredients needed to make our Chocolate Mud Cake recipe. Culinary professionals call this the Mise en Place, which means “Everything in its Place.”

Setting up your ingredients not only helps speed up the cooking process but also helps ensure you have all of the ingredients on hand to make the recipe.

Made with simple pantry ingredients

• Dark Chocolate
• All-purpose flour
• Unsalted butter
• Granulated sugar
• Unsweetened cocoa powder
• Baking powder
• Baking soda
• Table salt
• Vanilla extract
• Sour cream
• Heavy cream

Dark chocolate has the deepest flavor, but you could use part milk chocolate if you prefer a lighter flavor profile. I made the ganache using dark chocolate, but you can use white chocolate to make a ganache for a contrast of color and flavor for my classic mud cake.

Some recipes use self-raising flour, which you can incorporate, but you must eliminate the baking powder and salt from the dry ingredients.

You’ll also see caster sugar used instead of granulated sugar. Caster sugar is finer and dissolves more easily. It’s a good substitute, but you’ll need to reduce the amount of sugar by 5-10% unless you prefer a sweeter taste. I like to use caster sugar when making my Tiramisu recipe; it dissolves very nicely in the sabayon.

I use instant coffee or instant espresso when called for in baking recipes. Coffee enhances the natural chocolate flavor and takes my chocolate mud cake to a new level of deliciousness. And trust me, the cake will not taste like coffee.

Substitute hot coffee for water and instant coffee, and use decaf if you want to reduce your caffeine intake. You can also leave out the coffee, simply using hot water in the recipe.

• Add the flour, cocoa powder, sugar, baking soda, baking powder, and salt to a large mixing bowl.
• Whisk to combine the dry ingredients.
• Add the butter, chocolate, hot water, and instant coffee powder to a large saucepan over low heat.
• Heat until they have melted, mixing the ingredients together until smooth.
  *Scrape the bottom and sides of the pan with a rubber spatula as needed.
• Remove the pan from the heat and pour the melted chocolate into a large bowl to cool slightly (about 5 minutes).
• Add the eggs to the warm (not hot) chocolate mixture, whisking to combine.

• Add the sour cream and vanilla extract to the mixture, stirring to combine.
• Add the dry ingredients to the large bowl with the wet ingredients. Use an electric hand mixer (you can use a stand mixer or mix by hand) and mix just enough to combine. You want a smooth batter, but don’t be tempted to overmix; that will only make the cake tough.
  *Scrape the bottom and sides of the bowl as needed.
• Pour the cake batter into the prepared springform pan.
• Place the springform pan on the center rack of a preheated oven and bake for 75-90 minutes, or until a toothpick inserted in the center of the cake comes out clean.
  *The cake shouldn’t jiggle if you nudge the pan.
• Remove the cake pan from the oven and place it on a wire rack to cool for 30 minutes.
• After 30 minutes, remove the chocolate mud cake from the springform pan to finish cooling to room temperature.

• Once the cake cools completely, use a serrated knife to remove the dome and create a relatively flat surface.
• Add the heavy cream to a small saucepan and heat over medium-high heat until very hot. Do not let the cream boil.
• Pour the hot cream over the cut-up chocolate pieces (in a heatproof bowl) and let it sit for 3-5 minutes.
• Whisk the ingredients together until smooth and creamy.
• Let the ganache cool for 30 minutes until it has firmed up.
• Pour the chocolate ganache on top of the chocolate mud cake.
• Spread the ganache evenly over the top of the cooled cake using a frosting spatula.

If you prefer a more traditional frosting for the chocolate mud cake, you can use my chocolate buttercream or chocolate cream cheese frosting.

The whole cake is quite an impressive sight. And the good thing is it tastes even better than it looks. It’s the perfect chocolate mud cake!

Serve the chocolate mud cake with homemade whipped cream or vanilla ice cream for an extra special treat.

Store any leftover mud cake in an airtight container (or covered with plastic wrap), either refrigerated for 5-6 days or at room temperature for 3-4 days. You can freeze it by wrapping it tightly in plastic wrap and then in aluminum foil. Store frozen for up to 3 months.
