Yield
Serves 12 generous slices
Difficulty Level
Medium – ideal for bakers ready to impress with layers and homemade frosting
Ingredients
- For the Cake layers:
- 2 ½ cups all-purpose flour, sifted
- 1 ½ cups granulated sugar
- 1 cup unsweetened cocoa powder, preferably Dutch-processed
- 1 ½ teaspoons baking powder
- 1 ½ teaspoons baking soda
- 1 teaspoon fine sea salt
- 1 teaspoon ground cinnamon, optional but adds warmth
- 2 large eggs, at room temperature
- 1 cup whole milk, at room temperature
- ½ cup vegetable oil or melted coconut oil
- 2 teaspoons pure vanilla extract
- 1 cup hot brewed coffee or strong espresso, to intensify chocolate flavor
- For the fluffy Marshmallow Frosting:
- 3 large egg whites, at room temperature
- 1 ½ cups granulated sugar
- ¼ cup water
- 1 teaspoon vanilla extract
- Pinch of cream of tartar or a few drops of lemon juice
- Optional: 1 tablespoon marshmallow fluff for extra richness
Instructions

- Prepare Cake Layers: Preheat your oven to 350°F (175°C). Lightly grease and flour three 8-inch round cake pans or line them with parchment paper. This ensures easy release and perfect edges.
- Mix Dry Ingredients: In a large bowl, sift together flour, cocoa powder, baking powder, baking soda, salt, and cinnamon. mixing all the dry ingredients thoroughly allows an even rise and rich chocolate depth.
- Beat Wet Ingredients: In a separate bowl,whisk eggs,milk,oil,and vanilla until smooth. Slowly pour in the hot coffee while stirring to create a luxurious chocolate batter. The hot liquid helps dissolve the cocoa for an intense, velvety crumb.
- Combine and Pour: Gradually incorporate dry ingredients into the wet mixture with a spatula or electric mixer on low speed. Mix until just combined-overmixing can toughen the cake.
- Bake to Perfection: Divide batter evenly between pans.Bake for 28-32 minutes, or until a toothpick inserted in the center comes out clean. Avoid opening the oven too soon to prevent sinking layers.
- Cool Completely: Let the cakes cool in pans for 10 minutes, then turn out onto wire racks to cool completely. Proper cooling is essential before frosting to avoid melting or slipping layers.
- Prepare Marshmallow Frosting: Combine sugar and water in a small saucepan. heat until sugar dissolves and syrup reaches 240°F (soft-ball stage) on a candy thermometer. Meanwhile, beat egg whites with cream of tartar until soft peaks form.
- Beat Frosting to Glossy peaks: With mixer running,slowly drizzle hot sugar syrup into egg whites. Continue beating at high speed until stiff, glossy peaks form and the bowl feels neutral to touch (about 7-10 minutes). Stir in vanilla extract and marshmallow fluff if using, for extra silkiness.
- Assemble the cake: Place one layer on a serving plate. Spread a thick layer of marshmallow frosting evenly. Repeat with remaining layers.Use the frosting to generously coat the top and sides for an irresistible cloud-like finish.
- Chill and Set: Refrigerate the assembled cake for at least 30 minutes to allow frost to firm up slightly, making slicing easier and neater.
Tips for Success
- Boost Moisture: Adding coffee enhances chocolate flavor without imparting bitterness. you can substitute brewed tea or cold-brew coffee for a subtle twist.
- Egg Whites at Room Temperature: For fluffier marshmallow frosting,ensure egg whites are not cold-they whip better at room temp.
- Use a Candy Thermometer: Accurate sugar syrup temperature is key to perfect frosting. without it, the frosting may collapse or be grainy.
- Make Ahead: Cake layers can be baked and frozen for up to one month. Thaw completely before assembly. Marshmallow frosting is best prepared fresh but can be kept refrigerated in an airtight container for one day.
- Substitutions: For dairy-free, swap milk for almond or oat milk and use coconut oil. Avoid dark cocoa powder if a lighter, less bitter cake is preferred.
