Step‑by‑Step Instructions for Chocolate Fudge Cake with Salted Caramel Buttercream
Step 1: Prepare the Cake Batter
Preheat your oven to 180°C (350°F) and grease two 20cm (8-inch) cake pans, lining them with parchment paper. In a stand mixer, cream together room temperature butter, caster sugar, and vanilla extract until the mixture is light and fluffy—about 3-4 minutes. Add eggs one at a time, mixing well after each addition, creating a creamy batter.
Step 2: Combine Cocoa and Wet Ingredients
In a separate bowl, mix Dutch processed cocoa with hot water until it forms a smooth paste. Gradually, pour this cocoa mixture into the creamed butter mixture, blending until fully incorporated. Next, combine vinegar with whole milk and prepare to add this mixture alternately with sifted plain cake flour and leavening agents, ensuring the batter remains silky and smooth.
Step 3: Bake the Cake Layers
Dividing the rich chocolate fudge cake batter evenly between the two prepared pans, place them in the preheated oven. Bake for approximately 23 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs. Remove the cakes from the oven and let them cool in the pans for about 10 minutes before carefully transferring them to a wire rack to cool completely.
Step 4: Make the Salted Caramel
While the cake cools, start on the salted caramel. In a heavy-bottomed saucepan, melt together the caster and brown sugars over medium heat, stirring constantly to prevent burning. Once the sugars are fully melted and bubble, add the butter and heavy cream, stirring for one minute until the mixture thickens slightly. Finally, sprinkle in salt flakes, mixing well, and allow the caramel to cool down completely before using.
Step 5: Prepare the Ganache
For the dark chocolate ganache, chop your dark chocolate into small pieces and place in a heatproof bowl. In a small saucepan, heat the heavy cream until just before boiling, then pour it over the chocolate. Allow sitting for a couple of minutes before stirring until the mix is smooth and glossy. Set the ganache aside to cool slightly but still be pourable.
Step 6: Make the Salted Caramel Buttercream
In a clean mixing bowl, beat softened butter on high until fluffy, which should take about 5 minutes. Gradually add icing sugar a cup at a time, mixing on low until incorporated, then increase speed to combine fully. Fold in the cooled salted caramel until fully integrated, and if needed, refrigerate the buttercream briefly to firm up.
Step 7: Assemble the Cake
Once the cake layers are completely cooled, place one layer on a serving platter. Spread a generous layer of salted caramel buttercream on top, drizzle some salted caramel over the frosting, and then add the second cake layer. Repeat the process, adding more buttercream, and finish by pouring the dark chocolate ganache over the top, allowing it to gently cascade down the sides for a beautiful presentation.

Expert Tips for Chocolate Fudge Cake
-
Room Temperature Ingredients: Ensure all your ingredients, especially butter and eggs, are at room temperature. This helps create a smoother batter and ensures even baking.

Monitor Baking Time: Be vigilant about baking time; underbaking can cause the cake to sag and lose its shape. Check for doneness with a toothpick for the perfect bake.
-
Cool Properly: Allow the cake layers to cool completely before frosting. This prevents melting and ensures that your salted caramel buttercream stays perfect and fluffy on top.
-
Quality Ingredients: Using high-quality dark chocolate for ganache and salted caramel can elevate your Chocolate Fudge Cake exponentially, making it irresistibly rich and indulgent.

Chocolate Fudge Cake with Salted Caramel Buttercream Recipe FAQs
How do I select the best cocoa for this cake?
Choosing the right cocoa powder is essential for achieving the desired flavor and color in your Chocolate Fudge Cake. Dutch processed cocoa offers a richer, darker taste, while natural cocoa will lighten the cake’s color and slightly alter the flavor. If you’re unsure, stick with Dutch processed cocoa for a classic chocolate experience!
What is the best way to store leftovers?
To keep your leftover cake fresh, store it at room temperature in a cake dome or wrapped tightly in plastic wrap for up to 3 days. If you need to keep it longer, refrigerate it in an airtight container for up to a week. Just remember to bring it to room temperature before enjoying, as this helps revive its moist texture!
Can I freeze the Chocolate Fudge Cake?
Absolutely! You can freeze the whole cake or individual slices for up to 3 months. For best results, wrap the cake tightly in plastic wrap followed by aluminum foil to prevent freezer burn. When you’re ready to enjoy, let it thaw in the refrigerator overnight, and you’ll have a deliciously moist treat waiting for you!
What if my cake layers sink in the middle?
If your cake layers sag or sink in the middle, it could be due to underbaking or too much moisture in the batter. To troubleshoot, ensure that your oven is preheated properly and check for doneness using a toothpick insert before removing the layers. If you find they need more time, return them to the oven in small increments until they bake through. Consistency is key!
Is this cake safe for people with nut allergies?
While the Chocolate Fudge Cake with Salted Caramel Buttercream is free of nuts in its base form, be cautious if you decide to use variations like a peanut butter buttercream. Always confirm that the ingredients you choose are nut-free and prepared in nut-free environments to avoid cross-contamination. Enjoy worry-free with your loved ones!
