Ingredients You'll Need

Gathering the right ingredients is the first exciting step in making this irresistible cake. Each item plays a crucial role, from building deep chocolate flavor to ensuring that melt-in-your-mouth texture and that glossy, irresistible finish on top.

• 200 g dark chocolate: Choose a quality semi-sweet chocolate with around 70% cocoa for a rich base flavor.
• 150 g unsalted butter: Adds creaminess and helps create the cake’s tender crumb.
• 90 g vegetable oil: Keeps the cake moist and soft without weighing it down.
• 7 g vanilla extract: Enhances all the flavors with a sweet, aromatic note.
• 400 g caster sugar: Provides the perfect balance of sweetness and contributes to a smooth batter.
• 3 large eggs: Bind everything together and add richness; room temperature is key for the fluffiest results.
• 40 g unsweetened cocoa powder: Intensifies chocolate flavor and deepens color.
• 225 g all-purpose flour: The backbone of the cake, sifted to avoid lumps and keep it light.
• 1 ½ teaspoon baking powder: Ensures a perfect rise and airy texture.
• ½ teaspoon salt: Balances sweetness and enhances depth of flavor.
• 375 g boiling water: Helps to bloom the cocoa powder and instant coffee, unlocking intense flavors.
• 10 g instant coffee powder (optional): Secretly boosts chocolate notes without adding a coffee taste.
• 840 g dark cooking chocolate (for ganache): Key for silky, luscious frosting.
• 125 g unsalted butter (for ganache): Adds shine and richness to the ganache.
• 60 g glucose syrup: Stabilizes the ganache for perfect texture and prevents cracking.
• 375 g heavy cream: Creates that indulgent, creamy ganache consistency everyone dreams about.

How to Make One-Bowl Chocolate Fudge Cake (SO Moist!)

Step 1: Preheat and Prepare Your Pans

Start by preheating your oven to 150C for fan forced (or 170C if you don’t have a fan). Grease two 20cm cake tins with oil and line their bottoms with baking paper. This simple prep step prevents sticking and ensures your layers pop out beautifully.

Step 2: Melt Butter and Chocolate

Place the dark chocolate and butter in a heatproof bowl and melt gently, either microwaving for 30-second intervals while stirring or using a double boiler. This step is crucial to ensure a smooth, glossy chocolate base that sets the stage for a luscious cake.

Step 3: Mix in Sugar, Oil, and Eggs

Into the warm chocolate mixture, add your caster sugar, vegetable oil, and vanilla extract. Stir everything together with a spatula until well combined. Then whisk in the eggs one by one until your batter is smooth and velvety, promising the perfect rise and texture.

Step 4: Combine Dry Ingredients

Sift together flour, cocoa powder, baking powder, and salt directly over the wet chocolate mixture. Using a spatula, gently fold these dry ingredients in until no streaks remain. This gentle mixing keeps the cake tender without overworking the batter.

Step 5: Add Boiling Water Mixture

Combine boiling water and instant coffee powder (if using) to create a flavor-enhancing liquid. Carefully whisk this into your batter until smooth. This step thins the batter slightly, making it extra moist and unlocking the intense chocolate aroma.

Step 6: Bake to Perfection

Divide the batter evenly between your prepared pans and place them on the middle rack of your oven. Bake for 40 to 45 minutes until a toothpick inserted in the center comes out clean. Let them cool in the tins for 20 minutes before transferring to a wire rack to cool completely. Patience here rewards you with the best texture!

Step 7: Make the Decadent Ganache

For the ganache, melt together dark cooking chocolate, butter, heavy cream, and glucose syrup in the microwave or over a double boiler, stirring constantly. Once smooth and glossy, cover with plastic wrap resting directly on the surface to prevent a skin, then let set at room temperature for 3 to 4 hours until firm but still spreadable.

Step 8: Assemble and Frost the Cake

Place one cake layer on your serving plate and spread about one quarter of the ganache on top. Add the second cake layer and then cover the entire cake with the remaining ganache. For a beautiful finish, use a piping bag with a Wilton 1M tip to add elegant swirls. Every step brings you closer to slicing into this moist and dreamy cake.

How to Serve One-Bowl Chocolate Fudge Cake (SO Moist!)

Garnishes

Adding fresh strawberries, a sprinkle of edible gold dust, or a handful of toasted nuts provides not only a delightful contrast in texture but lovely bursts of color. A dusting of cocoa powder or powdered sugar can also elevate the rustic charm of your slice.

Side Dishes

Pair this cake with a scoop of vanilla bean ice cream or a dollop of freshly whipped cream for balance. A rich espresso or a glass of cold milk can complete the experience, making it feel like a special celebration in every bite.

Creative Ways to Present

Try layering individual portions in elegant glass jars with ganache and cake crumbs for a trendy parfait twist. Alternatively, cut the cake into mini squares and serve on a platter for easy sharing. Personalizing the presentation will make your guests feel extra special.

Make Ahead and Storage

Storing Leftovers

Wrap leftover slices tightly in plastic wrap and store in an airtight container in the fridge for up to three days. This keeps the cakes fresh and the ganache glossy, ready for another indulgent treat.

Freezing

You can freeze the unfrosted cake layers for up to three months. Wrap each layer several times in plastic wrap and then in a freezer-safe bag to protect against freezer burn. Thaw thoroughly in the fridge before assembling and frosting.

Reheating

Reheat individual slices gently in the microwave for about 20 seconds to bring back that warm, melty chocolate sensation without drying out the cake. Avoid overheating or the ganache may lose its silky texture.

FAQs

Can I skip the instant coffee powder?

Absolutely! The instant coffee powder is used to enhance the chocolate flavor but does not add a coffee taste. If you prefer, leaving it out will still result in a delicious cake.

Why is my cake not as moist as expected?

Using the correct amount of vegetable oil and boiling water is essential. Measuring ingredients by weight, as this recipe specifies, ensures accuracy. Also, avoid overbaking to maintain moistness.

Can I use milk chocolate instead of dark chocolate?

You can, but keep in mind that dark chocolate provides the rich, intense flavor and firm structure needed for the perfect fudge cake. Milk chocolate will make it sweeter and may change the texture.

Is glucose syrup necessary for the ganache?

Glucose syrup helps stabilize the ganache and keeps it smooth without cracking. You can substitute with corn syrup or leave it out, but the ganache might be less stable over time.

How long does it take for the ganache to set?

Typically, it needs 3 to 4 hours at room temperature to become firm but still spreadable. Avoid refrigerating it to set faster, as this can cause the ganache to become too hard and lose its silky texture.
