Devil’s Food Chocolate Cake with Black Walnut

Devil's food is chocolate cake at its most decadent — dark, moist, and almost sinfully rich. This version gives the classic real character by folding earthy black walnuts through the crumb, their bold, faintly wild flavor cutting through the deep chocolate beautifully. Finished with a glossy fudge frosting, it is a dramatic, old-fashioned cake, the kind that anchors a birthday table or a Sunday supper and leaves everyone reaching for a second slice.

The Deep, Moist Batter

Build a rich devil's food batter, dark with cocoa and kept moist by the right balance of liquid and fat. This is a cake that should be intensely chocolatey and tender, so mix it well and bake it just until set — a moist crumb is the soul of a proper devil's food.

Black Walnuts and Fudge Frosting

Fold the black walnuts through the batter so their earthy flavor runs all the way through, then blanket the cooled cake in glossy fudge frosting. The walnuts add a bold, grown-up depth that keeps the sweet fudge in check, and a scatter of them on top hints at the character within.

Devil’s Food Chocolate Cake with Black Walnut

A in batter hydration and flavor manipulation. By substituting standard water with highly carbonated citrus soda and dark brewed coffee, this deeply rich, black walnut-infused chocolate cake achieves an extraordinarily tender, aerated crumb, crowned with a dense, fudgy cocoa mixture.

Ingredients Method

Ingredients

  

The Batter

• 1 box high-quality Devil's Food Cake mix and required oil/eggs per box instructions
• ¾ cup lemon-lime soda such as Sprite, in place of water
• ¼ cup dark brewed coffee cooled (in place of water)
• 2 tablespoons black walnut flavoring extract

The Fudge Frosting

• 6 cups confectioners’ sugar
• ¾ cup premium unsweetened cocoa powder
• ¼ teaspoon kosher salt
• 4 tablespoons unsalted butter melted (½ stick)
• ½ cup dark brewed coffee cooled
• 2 tablespoons black walnut flavoring extract
• ⅓ cup whole milk or heavy cream

Method

 

Mix & Bake the Cake

1. Preheat the oven and prepare your baking pans according to the instructions on the Devil's Food cake mix box.
2. In a large mixing bowl, combine the dry cake mix with the oil and eggs required by the package instructions.
3. Crucially, discard the water measurement called for on the box. Instead, hydrate the batter by pouring in the ¾ cup of carbonated citrus soda and ¼ cup of dark brewed coffee. (The carbonation forces microscopic air pockets into the batter for a towering lift, while the coffee deepens the cocoa notes).
4. Stir in the 2 tablespoons of black walnut flavoring. Mix the batter thoroughly until smooth and unified.
5. Bake according to the package directions. Remove from the oven and allow the cakes to cool completely on wire racks before frosting.

Make the Frosting

1. While the cakes cool, build the frosting. Place the 6 cups of confectioners’ sugar, ¾ cup cocoa powder, and ¼ teaspoon kosher salt into the bowl of an electric stand mixer. Pulse briefly to combine the dry ingredients.
2. Add the melted butter, ½ cup of brewed coffee, 2 tablespoons of black walnut flavoring, and ⅓ cup of milk or cream directly into the bowl.
3. Beat on medium-high speed until the ingredients bind into a thick, highly glossy, fudgy batter. Scrape down the sides of the bowl as needed.

Frost the Cake

1. Assess the texture of the frosting: if it is too loose and weeping, beat in an additional spoonful of confectioners' sugar. If it is too dense and tears the cake crumb, stream in a tiny splash of milk until perfectly spreadable.
2. Generously frost the cooled layers, swirling the thick icing heavily over the top and sides of the cake. Serve immediately.
