Cake:
- 4 ounces bittersweet chocolate (70% cacao, chopped or chips)
- 1 cup dark unsweetened cocoa powder (e.g. Hershey’s Special Extra Dark)
- 1 3/4 cups dark coffee or water (boiling)
- 2 2/3 cups all-purpose flour
- 1 1/4 teaspoons baking soda
- 1/4 teaspoon baking powder
- 1 pinch kosher salt
- 1 cup sugar
- 1 cup dark brown sugar (packed)
- 1 1/3 cups mayonnaise (regular, not reduced-fat or fat-free; Hellman’s or Duke’s preferred)
- 2 large eggs
- 1 egg yolk
- 1 teaspoon vanilla extract
Frosting:
- 2 1/4 cups butter (softened)
- 1 1/2 cups confectioners’ sugar
- 3/4 cup unsweetened dark cocoa powder (e.g. Hershey’s Special Extra Dark)
- 1/2 cup hot double-strength coffee
- 1/2 cup sour cream
- 1 1/2 teaspoons vanilla extract
- 1 pinch kosher salt
- 10 ounces dark chocolate (chopped and melted)
- 1 tablespoon white corn syrup
- Preheat Oven: Set your oven to 350°F (175°C). Prepare three 8-inch cake pans by greasing and dusting them with cocoa powder to prevent sticking.
- Melt Chocolate: Microwave the bittersweet chocolate until just softened, about 1 minute, stirring to a smooth consistency.
- Mix Chocolate and Cocoa: In a bowl, combine the melted chocolate and 1 cup cocoa powder. Whisk in boiling coffee or water until smooth, then set aside.
- Prepare Dry Ingredients: Sift together flour, baking soda, baking powder, and salt into a separate bowl and set aside.
- Beat Sugars and Mayonnaise: Using an electric mixer on medium-high, beat sugar and brown sugar with mayonnaise until fully blended.
- Add Eggs: Incorporate eggs one at a time, beating well after each addition. Then beat in the egg yolk and vanilla extract.
- Combine Ingredients: Reduce mixer speed to low. Alternately add the dry ingredients and the chocolate mixture in four parts, beating well after each addition to form the batter.
- Fill Pans and Bake: Distribute batter evenly into prepared pans. Bake for approximately 30 minutes, or until a cake tester inserted in the center comes out clean.
- Cool Cakes: Allow cakes to cool 10 minutes in pans, then loosen edges and invert onto wire racks. Cool completely before frosting.
- Make Frosting: In a stand mixer with paddle attachment, beat softened butter on medium speed for about 6 minutes until pale and fluffy.
- Add Sugar and Cocoa: Sift confectioners’ sugar and cocoa powder together, then add to the butter at low mixer speed until blended.
- Add Liquids and Flavorings: With the mixer still on low, add hot double-strength coffee, sour cream, vanilla extract, and salt. Beat for 1 minute.
- Whip Frosting: Increase mixer speed to medium and whip the frosting for 2 minutes to aerate it.
- Add Melted Chocolate: Stir in melted dark chocolate and white corn syrup; beat until smooth, about 2 minutes.
- Assemble Cake: Spread frosting evenly between cooled cake layers and over the top and sides for a decadent finish.
- Optional Sheet Cake Instructions: For a sheet cake, grease and flour a 13×9-inch pan, pour in batter, and bake 30-35 minutes at 350°F. Cool completely and frost as desired.
Notes
- Use full-fat mayonnaise for best texture; reduced-fat versions will affect moisture and richness.
- Be sure to use high-quality bittersweet chocolate and dark cocoa powder to enhance chocolate intensity.
- Let cake layers cool completely before frosting to prevent melting the frosting.
- Double-strength coffee intensifies chocolate flavor and keeps the cake moist.
- Can be stored in an airtight container at room temperature for 2 days or refrigerated for up to 5 days.
- This cake freezes well; wrap tightly and freeze for up to 3 months.
