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 (for cake)
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. Line the bottoms with parchment paper.
Step 2: In a large bowl, whisk together the flour, cocoa powder, baking soda, baking powder, salt, and sugar.
Step 3: In a separate bowl, mix the buttermilk, vegetable oil, eggs, and vanilla extract. Pour the wet ingredients into the dry ingredients and mix until just combined.
Step 4: Carefully pour in the hot brewed coffee and mix on low speed until the batter is smooth. Stir in the chocolate chips gently. The batter will be thin — this is normal.
Step 5: 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.
Step 6: Let the cakes cool in the pans for 10 minutes before inverting them onto a wire rack to cool completely. Do not frost while warm.
Step 7: While the cakes cool, prepare the whipped cream frosting. Beat 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 over the top. Sprinkle half of the toffee bits over the caramel.
Step 9: Carefully place the second cake layer on top. Frost the top and sides of the entire cake with the whipped cream frosting.
Step 10: Drizzle the remaining caramel sauce over the top of the cake, letting it drip down the sides. Sprinkle the remaining toffee bits over the top for the final crunch.
Step 11: Chill the cake for at least 30 minutes before slicing and serving. This helps the layers set and the flavors meld.

Tips & Variations

For a richer chocolate flavor, use dark Dutch-processed cocoa powder instead of natural cocoa.
If you prefer a more stable frosting, substitute whipped cream with chocolate buttercream, especially for tall or transported cakes.
Add the final toffee topping just before serving to keep it crunchy, as moisture from the frosting and caramel can soften it over time.
Make the cake layers ahead of time by wrapping them tightly in plastic wrap. They keep well at room temperature for two days or can be frozen up to a month.

Storage

Store any leftover cake in an airtight container in the refrigerator. It will keep well for about 3 to 4 days. Keep in mind that the crunchy toffee bits will soften slightly as they absorb moisture from the frosting and caramel, so for the best texture, enjoy leftovers within the first couple of days. Bring slices to room temperature before serving if desired.

FAQs

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

Yes, you can substitute buttermilk by mixing 1 cup of milk with 1 tablespoon of white vinegar or lemon juice. Let it sit for five minutes until slightly curdled, and use it as a homemade buttermilk replacement. This helps tenderize the crumb and reacts with the baking soda for a moist cake.

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

Due to the whipped cream frosting, store leftovers in an airtight container in the refrigerator. It will stay fresh for about three to four days. Note that the toffee bits will soften over time, so it’s best to eat the cake within the first two days for maximum crunch.

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

To achieve a professional look, level the cake layers by slicing off any domes with a serrated knife once completely cool. Then apply a thin crumb coat layer of frosting to seal in crumbs; chill for 20 minutes before adding the final, thick frosting layer. This ensures smooth, straight sides like a bakery cake.

Ingredients

Scale

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

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 (such as crushed Heath or Skor bars)
1/2 cup extra caramel sauce for drizzling

Instructions

Preheat and Prepare 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 well combined.
Combine Wet Ingredients: In a separate bowl, mix the buttermilk (or milk plus vinegar), vegetable oil, eggs, and vanilla extract until smooth.
Make the Batter: Pour the wet mixture into the dry ingredients and stir gently until just combined. Carefully add the hot brewed coffee and mix on low speed until the batter is smooth and thin. Fold in the semi-sweet chocolate chips.
Bake the Cake Layers: Divide the thin batter evenly between the prepared 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.
Cool the Cake: Let the cakes cool in the pans for 10 minutes, then invert them onto cooling racks and allow them to cool completely before frosting.
Prepare Whipped Cream Frosting: While the cakes cool, beat the heavy whipping cream, powdered sugar, and vanilla extract together until stiff peaks form, creating a light, airy frosting.
Assemble the Cake: Place one cooled cake layer on a serving plate. Spread half of the salted caramel sauce over the top, then sprinkle half of the toffee bits evenly over the caramel.
Layer and Frost: Carefully place the second cake layer on top. Frost the top and sides of the entire cake with the whipped cream frosting, covering it evenly but without worrying about perfection.
Add Final Touches: Drizzle the remaining caramel sauce over the top, allowing it to drip down the sides. Sprinkle the remaining toffee bits over the top for added crunch and sparkle.
Chill and Serve: Refrigerate the assembled cake for at least 30 minutes before slicing to allow the layers to set and flavors to meld. Add the last toffee bits right before serving for maximum crunch.

Notes

For a deeper, richer chocolate flavor, substitute the cocoa powder with dark dutched cocoa powder.
If a stable, long-lasting frosting is needed (e.g., for tall cakes or transportation), replace the whipped cream frosting with chocolate buttercream.
To maintain crunchy toffee, add the final sprinkling of toffee bits just before serving, as moisture from frosting or caramel can soften them.
You can make the cake layers ahead of time; tightly wrap cooled layers in plastic wrap and store at room temperature for two days or freeze for up to a month.
Whipped cream frosting is best made the day you frost the cake to prevent it from becoming weepy.
Store leftover cake in an airtight container in the refrigerator for up to 3-4 days; note that the toffee bits will soften over time.
