1½ tsp baking powder – Adds lift and balances density.
1½ tsp baking soda – Reacts with cocoa for additional rise.
1 tsp salt – Enhances chocolate intensity and balances sweetness.
2 large eggs – Bind ingredients and provide richness.
1 cup whole milk – Adds moisture and softens crumb.
½ cup vegetable oil – Ensures tenderness and prevents dryness.
2 tsp vanilla extract – Rounds out chocolate notes.
1 cup boiling water – Activates cocoa and creates a pourable, high-hydration batter.

For the Caramel Sauce

1 cup granulated sugar – Forms the caramel base through controlled melting.
6 tbsp unsalted butter – Adds richness and smooth texture.
½ cup heavy cream – Creates a pourable, glossy sauce.
1 tsp vanilla extract – Enhances caramel complexity.
Pinch of salt – Balances sweetness and deepens flavor.

For the Toffee Topping

Step-by-Step Instructions

Prepare the Cake Pans

Preheat the oven to 350°F (175°C) and grease and flour two 9-inch round cake pans, ensuring full coverage to prevent sticking.

Mix the Dry Ingredients

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

Incorporate Wet Ingredients

Add eggs, milk, oil, and vanilla extract to the dry mixture. Beat on medium speed for about 2 minutes until smooth and cohesive.

Add Boiling Water

Slowly stir in the boiling water. The batter will be thin—this is essential for creating a moist, tender cake.

Bake the Cakes

Divide batter evenly between pans and bake for 30–35 minutes, until a toothpick inserted in the center comes out clean. Cool for 10 minutes in pans, then transfer to wire racks to cool completely.

Make the Caramel Sauce

Heat sugar in a saucepan over medium heat, stirring constantly until melted and amber-colored. Carefully add butter and cream, stirring until smooth, then finish with vanilla and salt. Cool slightly before using.

Assemble the Cake

Place one cake layer on a serving plate, drizzle generously with caramel sauce, and sprinkle with toffee bits. Top with the second layer and repeat.

Finish and Garnish

Drizzle with melted chocolate if desired and garnish just before serving.

Recipe Notes & Tips

Thin Batter Is Correct – High hydration is key to the cake’s moist texture.
Caramel Timing Matters – Remove sugar from heat as soon as it reaches amber to avoid bitterness.
Cool Layers Fully – Warm cake can cause caramel to soak in too quickly and destabilize layers.
Use a Serrated Knife – Ensures clean slices through toffee bits.
Salted Caramel Upgrade – Increase salt slightly for a more pronounced sweet-salty contrast.

Troubleshooting Common Issues

Cake Sinks in the Center – Ensure oven is fully preheated and avoid overmixing.

Dry Cake Texture – Check oven calibration and avoid overbaking.
Toffee Softens Too Much – Add toffee just before serving for maximum crunch.

Why This Recipe Works

The chocolate cake relies on oil and boiling water to create a high-moisture batter that bakes into a soft, resilient crumb. Cocoa powder blooms fully under heat, intensifying flavor without heaviness. The caramel sauce introduces fat and sugar complexity, while toffee adds necessary crunch to balance the softness of the cake. At approximately 520 calories per slice, this dessert is intentionally rich and best enjoyed as a special-occasion indulgence.

Final Thoughts

This Chocolate Caramel Toffee Cake is a celebration of bold flavors and contrasting textures, delivering maximum payoff for moderate effort. While undeniably indulgent, thoughtful portioning and optional lighter garnishes—like fresh fruit—allow flexibility. If you’re looking for a show-stopping dessert that leans fully into decadence, this recipe delivers every time.
