Ingredients
For the Chocolate Cake
- 2 cups all-purpose flour
- 2 cups granulated sugar
- ¾ cup unsweetened cocoa powder
- 2 teaspoons baking powder
- 1½ teaspoons baking soda
- 1 teaspoon salt
- 2 large eggs
- 1 cup buttermilk
- ½ cup vegetable oil
- 2 teaspoons vanilla extract
- 1 cup hot water or hot coffee
For the Salted Caramel Frosting
- 1 cup unsalted butter, softened
- 1 cup caramel sauce
- 3–4 cups powdered sugar
- 1 teaspoon vanilla extract
- ½ teaspoon sea salt
- 2–3 tablespoons heavy cream, as needed
For the Chocolate Fudge Ganache
- 1 cup semi-sweet or dark chocolate chips
- ½ cup heavy cream
For the Topping
- ½ cup caramel sauce
- Flaky sea salt, to taste
- Chocolate shavings, optional
Instructions
1. Bake the Chocolate Cake
Preheat your oven to 350°F (175°C). Grease and line three 8-inch round cake pans with parchment paper.
In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
Add the eggs, buttermilk, vegetable oil, and vanilla. Beat until the mixture is smooth.
Slowly pour in the hot water or coffee while mixing. The batter will be quite thin, but that’s exactly what you want for a moist chocolate cake.
Divide the batter evenly between the prepared pans.
Bake for approximately 22–28 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
Allow the cakes to cool in their pans for about 10 minutes, then transfer them to a wire rack to cool completely.
2. Make the Caramel Frosting
Beat the softened butter until light and creamy.
Add the caramel sauce, vanilla, and sea salt. Gradually add the powdered sugar, one cup at a time, beating well after each addition.
Add a little heavy cream if the frosting is too thick. Continue beating until smooth and fluffy.
3. Prepare the Fudge Ganache
Place the chocolate chips in a heatproof bowl.
Warm the heavy cream until it is hot but not boiling. Pour it over the chocolate and let it sit for 2–3 minutes.
Stir slowly until the chocolate melts completely and the mixture becomes smooth and glossy.
Allow the ganache to cool until it reaches a spreadable consistency.
4. Assemble the Cake
Place the first chocolate cake layer on a serving plate.
Spread a generous layer of salted caramel frosting over the top, followed by a drizzle of caramel sauce.
Add the second cake layer and repeat.
Place the final cake layer on top and cover the entire cake with the remaining caramel frosting.
Smooth the sides and top with a spatula or cake scraper.
5. Add the Chocolate Fudge Layer
Spread the cooled chocolate ganache over the top of the cake, allowing a little to gently drip down the sides.
Drizzle additional caramel sauce over the ganache.
Finish with a light sprinkle of flaky sea salt and chocolate shavings if desired.
Helpful Tips
Use room-temperature ingredients. Eggs, buttermilk, and butter at room temperature generally combine more evenly.
Don’t skip the hot coffee. If you choose coffee instead of water, it won’t necessarily make the cake taste like coffee—it can simply deepen the chocolate flavor.
Cool the cake completely before frosting. Warm cake can melt the caramel frosting and make assembly difficult.
Don’t overdo the salt. Caramel and chocolate are already rich flavors, so a small amount of flaky sea salt provides plenty of contrast.
Chill before slicing. Refrigerating the assembled cake for 30–60 minutes can make it easier to cut into neat layers.
Serving
For the best texture and flavor, allow the cake to sit at room temperature for about 20–30 minutes before serving.
Serve each slice with an extra drizzle of caramel sauce for an especially decadent finish.
