Ingredients

Scale

Cake 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

Frosting & Toppings

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

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, 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 Batter: Pour the wet ingredients into the dry ingredients and mix gently until just combined. Then carefully pour in the hot brewed coffee and mix on low speed until the batter is smooth. Stir in the semi-sweet chocolate chips. Note that the batter will be thin.
Bake the Cakes: Divide the batter evenly between the prepared cake pans. Bake in the preheated oven for 30 to 35 minutes or until a wooden pick inserted into the center comes out clean.
Cool Cakes: Let the cakes cool in the pans for 10 minutes. Then invert them onto a wire rack to cool completely before assembly.
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 smooth and fluffy frosting.
Assemble Cake – Layering: 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 for added crunch.
Assemble Cake – Final Layer and Frosting: Carefully place the second cake layer on top. Frost the top and sides of the entire cake generously with the whipped cream frosting.
Decorate with Caramel and Toffee: Drizzle the remaining caramel sauce over the top of the cake, allowing it to drip down the sides. Sprinkle the remaining toffee bits over the top for a final crunchy texture.
Chill and Serve: Chill the cake in the refrigerator for at least 30 minutes before slicing and serving to help the layers set and flavors meld.

Notes

Use hot brewed coffee to enhance the chocolate flavor without overpowering the cake.
If buttermilk is unavailable, substitute with regular milk mixed with 1 tablespoon of white vinegar.
Line cake pans with parchment paper to ensure easy removal of cakes after baking.
The batter will be thin; this is normal and helps create a moist cake.
Store-bought caramel sauce is convenient, but homemade caramel adds a rich depth of flavor.
Chilling the cake helps the frosting set and makes slicing easier.
Toffee bits add a delightful crunch but can be omitted or substituted depending on dietary restrictions.
