Ingredients
The foundation of this cake is a rich chocolate sponge made with high‑quality cocoa and butter for depth. The caramel‑toffee sauce blends brown sugar, butter, and a splash of heavy cream to achieve a buttery sheen, while a pinch of sea‑salt lifts the sweetness. The crunchy toffee topping adds texture, and the final ganache brings everything together with a glossy finish.
Cake Layers
- 1 ½ cups all‑purpose flour
- ¾ cup unsweetened cocoa powder
- 1 ½ teaspoons baking powder
- ½ teaspoon baking soda
- ¼ teaspoon salt
- ¾ cup unsalted butter, softened
- 1 ½ cups granulated sugar
- 3 large eggs, room temperature
- 1 ½ teaspoons vanilla extract
- ¾ cup whole milk
Caramel‑Toffee Sauce
- 1 cup brown sugar, packed
- ½ cup unsalted butter
- ¼ cup heavy cream
- ½ teaspoon sea‑salt flakes
Toffee Crunch Topping
- ½ cup granulated sugar
- ¼ cup unsalted butter, melted
- ¼ cup chopped toasted almonds (optional)
Chocolate Ganache
- 8 oz semi‑sweet chocolate, chopped
- ½ cup heavy cream
- 1 tablespoon unsalted butter
These ingredients work together to create a balanced dessert. The cocoa and butter give the cake a tender crumb, while the brown sugar and butter in the sauce produce a deep caramel flavor that’s brightened by sea‑salt. The toffee topping adds a caramelized crunch that contrasts beautifully with the silky ganache, ensuring every forkful is a textural adventure.
Step-by-Step Instructions
Preparing the Cake Batter
Begin by preheating your oven to 350°F (175°C) and greasing two 9‑inch round cake pans. In a medium bowl whisk together flour, cocoa powder, baking powder, baking soda, and salt; this ensures even distribution of leavening agents. In a large bowl, beat softened butter and sugar until light and fluffy—about 3‑4 minutes—so the batter will rise properly.
Baking & Layering
- Incorporate Eggs. Add eggs one at a time, beating well after each addition. This creates an emulsion that traps air, giving the cake a tender crumb. Finish with vanilla extract for aromatic depth.
- Combine Dry & Wet. Alternate adding the flour mixture and milk to the butter‑egg blend, beginning and ending with the dry ingredients. Mix on low speed just until combined; over‑mixing would develop gluten and make the cake dense.
- Divide & Bake. Evenly split the batter between the prepared pans, smoothing the tops with a spatula. Bake for 22‑25 minutes, or until a toothpick inserted in the center emerges clean with a few moist crumbs.
- Cool. Let the cakes cool in the pans for 10 minutes, then turn onto a wire rack to cool completely. This prevents them from breaking when you later slice and stack.
Making Caramel‑Toffee Sauce & Crunch
- Caramel Base. In a medium saucepan melt butter over medium heat, then whisk in brown sugar. Continue stirring until the mixture bubbles and turns a deep amber, about 3‑4 minutes.
- Finish the Sauce. Slowly pour in heavy cream while whisking; the mixture will rise vigorously. Reduce heat to low and simmer for 2 minutes, then stir in sea‑salt flakes. Set aside to cool slightly.
- Toffee Crunch. In a separate skillet melt butter, add granulated sugar, and stir constantly over medium‑high heat until the sugar caramelizes and turns a golden brown. Remove from heat, fold in chopped almonds if using, and spread onto parchment to cool. Once hardened, break into coarse pieces.
Assembling the Cake
- First Layer. Place one cooled cake round on a serving plate. Drizzle half of the caramel‑toffee sauce over the surface, allowing it to soak into the crumb.
- Second Layer. Position the second cake on top, then pour the remaining sauce, spreading gently with a spatula.
- Ganache. Heat heavy cream until just simmering, then pour over chopped chocolate. Let sit for 1 minute, whisk until smooth, and stir in butter for shine. Pour the ganache over the top of the cake, letting it drip down the sides for a dramatic effect.
- Finish with Crunch. Sprinkle the broken toffee pieces evenly over the ganache while it’s still soft. The ganache will set, sealing the crunch into the surface. Refrigerate for 20 minutes before slicing to ensure clean cuts.
Tips & Tricks
Perfecting the Recipe
Room‑Temp Ingredients. Use eggs, butter, and milk at room temperature; they blend more evenly and give the cake a lighter texture.
Don’t Overmix. Stir the batter only until flour disappears. Overmixing creates gluten, resulting in a dense, rubbery crumb.
Even Layers. Weigh the batter before dividing between pans to ensure both layers are the same height, which helps the cake stack evenly.
Cool Completely. Allow cakes to cool fully before adding sauce; a warm cake will melt the caramel too quickly, making it run off.
Flavor Enhancements
Add a splash of espresso to the batter for deeper chocolate notes, or stir a teaspoon of orange zest into the caramel‑toffee sauce for bright citrus contrast. A pinch of smoked sea‑salt on the ganache just before serving adds an elegant, savory finish.
Common Mistakes to Avoid
Avoid letting the caramel sauce boil too vigorously; it can scorch and become bitter. Also, don’t skip the resting time after assembling—the ganache needs to set, otherwise slices will slide apart and lose their clean edges.
Pro Tips
Use a Kitchen Scale. Measuring flour and chocolate by weight yields consistent results, especially for delicate cakes.
Warm the Ganache Slightly. Before pouring, let the ganache sit at room temperature for 5 minutes; it will spread more smoothly and create a glossy finish.
Toast the Almonds. Lightly toast almonds before folding them into the toffee; this intensifies their nutty flavor and adds a subtle crunch.
Serve Slightly Warm. Warm each slice for 30 seconds in a low oven; the ganache becomes silky, and the caramel softens for an indulgent mouthfeel.
Variations
Ingredient Swaps
Swap semi‑sweet chocolate for dark chocolate (70 % cacao) for a richer, slightly bitter profile. Replace almonds with crushed pretzel pieces for a salty crunch, or use hazelnuts for a toasted, buttery flavor. Coconut milk can substitute heavy cream in the caramel for a dairy‑free twist.
Dietary Adjustments
For gluten‑free, use a 1‑to‑1 gluten‑free flour blend and ensure the cocoa powder is certified gluten‑free. To make the cake vegan, replace butter with coconut oil, use aquafaba or a flax‑egg mixture, and swap dairy cream with full‑fat coconut cream. A sugar‑free version can use erythritol in place of granulated sugar for the toffee.
Serving Suggestions
Pair each slice with a dollop of lightly sweetened whipped cream or a scoop of vanilla bean ice cream. Fresh berries—raspberries or strawberries—add a bright, acidic counterpoint. For an adult twist, drizzle a little bourbon‑infused caramel sauce over the top.
Storage Info
Leftover Storage
Allow any leftovers to cool completely, then wrap the whole cake tightly in plastic wrap and store in an airtight container. It will keep in the refrigerator for up to 4 days. For longer storage, slice the cake, wrap individual pieces, and freeze for up to 3 months; this preserves both texture and flavor.
Reheating Instructions
To enjoy a slice as if it were fresh, preheat your oven to 300°F (150°C), place a slice on a baking sheet, cover loosely with foil, and warm for 10‑12 minutes. The ganache will melt back to a silky sheen while the toffee remains crunchy. A microwave on medium for 30 seconds works in a pinch, but the oven method yields the best texture.
