Chocolate Fudge Birthday Cake with Salted Caramel

I still remember the first time I baked this chocolate fudge birthday cake with salted caramel for my brother’s birthday and how the smell alone made everyone gather in the kitchen before it had even cooled. I had been searching for a dessert that felt indulgent yet balanced and something that could impress while still offering that homemade touch and this recipe delivered that and more with its rich chocolate layers and a smooth caramel drip that made everyone swoon.

Ever since that celebration and because of how much joy it brought us and how many compliments it earned and how delicious it turned out I’ve made this cake part of every special occasion in our family. Whether it’s birthdays or anniversaries or even a simple dinner party this cake becomes the highlight and it’s truly a showstopper that looks elegant but is easier to pull off than you’d think.

Ingredients

• Here’s what I use for this recipe. You can always make substitutions if you prefer!
• All-purpose flour – Provides structure and holds everything together.
• Unsweetened cocoa powder – Adds deep chocolate flavor to the cake.
• Baking powder – Helps the cake rise and become fluffy.
• Baking soda – Gives an extra lift and balances the cocoa’s acidity.
• Salt – Enhances the chocolate and caramel flavors.
• Eggs – Bind the ingredients and give the cake richness.
• Granulated sugar – Sweetens the cake and adds moisture.
• Brown sugar – Adds depth and a subtle molasses flavor.
• Buttermilk – Keeps the cake incredibly moist and tender.
• Vegetable oil – Ensures a soft crumb and helps preserve freshness.
• Vanilla extract – Adds a warm, aromatic note to the batter.
• Hot coffee – Deepens the chocolate flavor without tasting like coffee.
• Heavy cream – Used in the salted caramel and buttercream for smooth texture.
• Unsalted butter – Forms the base of the buttercream and caramel.
• Powdered sugar – Sweetens and thickens the buttercream.
• Semi-sweet chocolate – Melted into the buttercream for a rich finish.
• Sea salt – Brings out the flavor in the caramel topping.

Tools You’ll Need

• Mixing bowls – To combine wet and dry ingredients separately.
• Electric mixer – Helps create a smooth and fluffy buttercream.
• Cake pans – Essential for baking even cake layers.
• Whisk – Perfect for mixing dry ingredients and breaking up clumps.
• Saucepan – Used for making the salted caramel from scratch.
• Offset spatula – Great for spreading buttercream evenly between layers.
• Piping bag with star tip – For decorating the top with buttercream swirls.
• Cooling rack – Allows the cakes to cool properly without becoming soggy.
• Cake turntable (optional) – Makes frosting and decorating much easier.

Instructions

Step 1: Preheat the Oven

I start by preheating my oven to 350°F and greasing three 8-inch round cake pans and then lining the bottoms with parchment paper for easy release.

Step 2: Mix the Dry Ingredients

In a large bowl, I whisk together flour, cocoa powder, baking powder, baking soda and salt until evenly combined and lump-free.

Step 3: Blend the Wet Ingredients

In a separate bowl, I beat the eggs with both sugars until fluffy and then I mix in the buttermilk, oil and vanilla until it’s smooth and creamy.

Step 4: Add the Coffee

Next, I slowly pour in the hot coffee while mixing on low speed and this really brings out the depth of the chocolate flavor.

Step 5: Combine and Pour

I gradually add the dry mixture to the wet ingredients and stir until just combined then I divide the batter evenly into the cake pans and tap them on the counter to release air bubbles.

Step 6: Bake and Cool

I bake the layers for about 30–35 minutes until a toothpick comes out clean and after that I let them cool in the pans for 10 minutes before transferring them to wire racks.

Step 7: Make the Salted Caramel

While the cakes cool, I melt butter in a saucepan then stir in brown sugar and heavy cream and cook for 5–7 minutes until thickened and bubbling and then I stir in the sea salt and let it cool.

Step 8: Prepare the Chocolate Buttercream

In a mixing bowl, I beat the butter until fluffy then I gradually add powdered sugar, cocoa powder and melted chocolate and finish with a splash of cream until it’s silky and spreadable.

Step 9: Assemble the Cake

I stack the cake layers with generous amounts of buttercream between each and use an offset spatula to smooth the sides then I pour the cooled caramel over the top and let it drip naturally.

Step 10: Decorate and Serve

Finally, I pipe swirls of buttercream around the top edge using a star tip and then I chill the cake for at least 30 minutes so everything sets before slicing and serving.

Tips

If your caramel feels too runny I suggest letting it cool longer before pouring it over the cake and for a deeper chocolate flavor I sometimes add a handful of mini chocolate chips between the layers. I also recommend refrigerating the cake if you’re making it a day ahead and then letting it sit at room temperature for 30 minutes before serving.

Ways to Serve
