Ingredients

1 3/4 cups all-purpose flour
3/4 cup unsweetened cocoa powder
1 1/2 teaspoons baking soda
1 1/2 teaspoons baking powder
1 teaspoon salt
2 cups granulated sugar
1 cup buttermilk (or milk mixed with 1 tablespoon white vinegar)
1/2 cup vegetable oil
2 large eggs
1 teaspoon vanilla extract
1 cup hot brewed coffee
1 cup semi-sweet chocolate chips
1 cup salted caramel sauce (store-bought or homemade)
1 cup heavy whipping cream
1/4 cup powdered sugar
1 teaspoon vanilla extract (for frosting)
1 1/2 cups toffee bits (like crushed Heath or Skor bars)
1/2 cup extra caramel sauce for drizzling

Instructions

Step 1: Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans and line the bottoms with parchment paper to prevent sticking.
Step 2: In a large bowl, whisk together the flour, cocoa powder, baking soda, baking powder, salt, and sugar until well combined.
Step 3: In a separate bowl, mix the buttermilk, vegetable oil, eggs, and vanilla extract. Pour the wet ingredients into the dry ingredients and stir until just combined.
Step 4: Carefully pour in the hot brewed coffee and mix gently on low speed until the batter becomes smooth. The batter will be thin—this is normal and creates a moist cake. Fold in the chocolate chips.
Step 5: Divide the batter evenly between the prepared cake pans and bake for 30 to 35 minutes. Check doneness by inserting a wooden pick in the center; it should come out clean or with a few moist crumbs.
Step 6: Let the cakes cool in their pans for 10 minutes, then invert onto a wire rack to cool completely before frosting.
Step 7: While the cakes cool, prepare the frosting by beating the heavy whipping cream, powdered sugar, and vanilla extract until stiff peaks form.
Step 8: To assemble, place one cooled cake layer on your serving plate. Spread half of the salted caramel sauce evenly on top, then sprinkle half the toffee bits over the caramel.
Step 9: Place the second cake layer on top. Frost the entire cake—top and sides—with the whipped cream frosting.
Step 10: Drizzle the remaining caramel sauce over the top, letting it drip down the sides. Finish by sprinkling the remaining toffee bits for added crunch.
Step 11: Chill the cake in the refrigerator for at least 30 minutes before slicing to allow the layers to set nicely.

Tips & Variations

For a deeper chocolate flavor, use dark cocoa powder instead of natural cocoa powder.
If you want a frosting that holds up better, especially for tall cakes or warm environments, substitute whipped cream with a sturdy chocolate buttercream.
To keep your toffee bits crunchy, add them on top just before serving to avoid moisture softening them.
Make the cake layers ahead of time by wrapping them tightly in plastic wrap; store at room temperature for up to two days or freeze for up to a month.

Storage

Store leftovers in an airtight container in the refrigerator for three to four days. The whipped cream frosting means the cake is best eaten within this time frame. Note that the toffee bits will soften over time as they absorb moisture from the frosting and caramel. Reheat slices gently at room temperature if desired, but avoid microwaving to preserve texture.

How to Serve

Serve this delicious recipe with your favorite sides.

FAQs

Can I use milk instead of buttermilk in this chocolate caramel toffee crunch cake?

Yes, you can. To replicate buttermilk, stir 1 tablespoon of white vinegar or lemon juice into 1 cup of regular milk and let it sit for about five minutes until slightly curdled. This substitute helps tenderize the cake and reacts with the baking soda for the best texture.

What is the best way to store leftover chocolate toffee celebration cake?

Because the frosting is whipped cream-based, keep the cake in an airtight container in the fridge and consume within 3-4 days. The toffee bits will soften over time, so for maximum crunch, add fresh toffee topping just before serving leftover slices.

How can I make this a true bakery style chocolate cake?

For a professional look, level the tops of your cooled cake layers with a serrated knife to create flat surfaces. Then apply a thin crumb coat of frosting and chill the cake for 20 minutes before adding the final thick layer of frosting. This process seals crumbs and gives a smooth finish.

Ingredients

Scale

For the Rich Cocoa Layers

1 3/4 cups all-purpose flour
3/4 cup unsweetened cocoa powder
1 1/2 teaspoons baking soda
1 1/2 teaspoons baking powder
1 teaspoon salt
2 cups granulated sugar
1 cup buttermilk (or milk mixed with 1 tablespoon white vinegar)
1/2 cup vegetable oil
2 large eggs
1 teaspoon vanilla extract
1 cup hot brewed coffee
1 cup semi-sweet chocolate chips

For the Whipped Cream Frosting and Assembly

1 cup salted caramel sauce (store-bought or homemade)
1 cup heavy whipping cream
1/4 cup powdered sugar
1 teaspoon vanilla extract (for frosting)
1 1/2 cups toffee bits (like crushed Heath or Skor bars)
1/2 cup extra caramel sauce for drizzling

Instructions

Prepare Baking Pans: Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans and line the bottoms with parchment paper to prevent sticking.
Mix Dry Ingredients: In a large bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking soda, baking powder, salt, and granulated sugar until evenly combined.
Combine Wet Ingredients: In a separate bowl, mix the buttermilk, vegetable oil, eggs, and vanilla extract thoroughly.
Make Cake Batter: Pour the wet ingredients into the dry ingredients and mix until just combined. Then carefully pour in the hot brewed coffee and blend on low speed until the batter is smooth. Stir in the semi-sweet chocolate chips gently. Expect the batter to be thin.
Bake Cake Layers: Divide the batter evenly between the prepared cake pans. Bake for 30 to 35 minutes or until a wooden pick inserted into the center comes out clean or with a few moist crumbs. Let the cakes cool in the pans for 10 minutes, then invert onto wire racks to cool completely.
Make Whipped Cream Frosting: While the cake cools, beat heavy whipping cream, powdered sugar, and vanilla extract together until stiff peaks form, creating a light and fluffy frosting.
Assemble Cake: Place one cooled cake layer on a serving plate. Spread half of the salted caramel sauce evenly over the top, then sprinkle half of the toffee bits.
Layer and Frost: Carefully place the second cake layer on top. Frost the entire cake, covering top and sides, with the whipped cream frosting.
Finish Decoration: Drizzle the remaining caramel sauce over the cake, allowing it to drip down the sides, and sprinkle the rest of the toffee bits on top for crunchy texture.
Chill Before Serving: Refrigerate the assembled cake for at least 30 minutes to let the layers set before slicing and serving.

Notes

For a richer chocolate flavor, substitute standard cocoa powder with dark Dutch-processed cocoa powder.
If you want a more stable frosting suitable for warm conditions or transport, replace the whipped cream with a chocolate buttercream frosting.
Add the final toffee bit topping just before serving to maintain maximum crunchiness; toffee softens when exposed to moisture over time.
