INGREDIENTS
Cake (yields 2 layers; repeat recipe):
- 3 large eggs
- 1½ cups/300 grams granulated sugar
- ¾ cup/75 grams unsweetened cocoa powder
- ¾ cup/165 grams oil
- 1 cup/240 grams whole milk
- 2 cups/280 grams self-rising flour
- ½ teaspoon/3 grams baking soda
- 1 cup/240 grams hot water
Ganache:
- 21 ounces/600 grams dark chocolate, finely chopped
- 3 cups/720 grams heavy cream
- 1½ ounces/40 grams unsalted butter
Syrup:
- ½ cup/100 grams granulated sugar
- ½ cup/120 grams water
- 3 tablespoons unsweetened cocoa powder
INSTRUCTIONS
- Heat the oven to 325°F/165°C. Grease and line two 9-inch/22-centimeter round cake pans with parchment paper.
- Make the ganache: Place the chocolate and butter in a large heatproof bowl. Bring the cream just to a simmer, then pour it over the chocolate mixture. Let stand for 1 minute, then blend with an immersion blender until smooth and glossy. Press plastic wrap directly onto the surface and refrigerate until thickened and spreadable, at least 4 hours.
- Make the cake: In a large bowl, whisk the eggs and sugar until slightly thickened and pale. Whisk in the oil until fully incorporated. Sift together the flour, cocoa powder and baking soda, then fold into the egg mixture. Stir in the milk until combined. Add the hot water and whisk just until the batter is smooth and fluid.
- Divide the batter evenly between the prepared pans. Bake until the tops spring back lightly and a toothpick inserted in the center comes out with moist crumbs, 35 to 40 minutes. Cool in the pans for 15 minutes, then turn out onto racks and cool completely. Repeat the recipe to produce 4 layers total.
- Make the syrup: In a small saucepan, combine the sugar, water and cocoa powder. Bring to a boil over medium heat, stirring until dissolved. Remove from heat and cool completely.
- If necessary, level the cakes with a serrated knife. Place one layer on a serving plate and brush generously with syrup. Spread about one-third of the ganache evenly over the top, taking it to the edges. Top with a second layer and repeat. Continue with the third layer. Place the final layer on top and brush lightly with syrup.
- Frost the top and sides with the remaining ganache, smoothing with an offset spatula. Refrigerate until set, at least 1 hour. Slice with a warm knife for clean edges.
FAQ
Can I make the 4 layer chocolate cake in advance?
This 4 layer chocolate cake is well suited for advance preparation because both the cake layers and the ganache benefit from resting time. The cake layers can be baked up to two days ahead, cooled completely, wrapped tightly in plastic wrap, and stored at room temperature. For longer storage, wrap each layer in plastic and then foil, and freeze for up to one month.
Thaw overnight in the refrigerator before assembling. The ganache should be prepared at least four hours in advance to allow it to thicken properly, but it can be refrigerated for up to three days. If fully assembled, the 4 layer chocolate cake can be refrigerated for 24 to 48 hours before serving. Allow it to sit at room temperature for 30 to 60 minutes before slicing to ensure the ganache softens slightly and the crumb texture is at its best.
Can I substitute all-purpose flour for self-rising flour?
For every 2 cups of self-rising flour, use 2 cups all-purpose flour plus 3 teaspoons baking powder and ½ teaspoon fine salt. Since the recipe already includes ½ teaspoon baking soda, keep that amount unchanged unless you are modifying acidity elsewhere in the formula.
Self-rising flour contains a balanced ratio of flour, baking powder, and salt, which affects structure and rise. Improper substitution can result in a dense or uneven crumb. Sifting the dry ingredients thoroughly ensures even distribution of leavening agents. Accurate measurement by weight is strongly recommended when modifying flour types to maintain the intended structure of the 4 layer chocolate cake.
How do I keep the layers moist in a 4 layer chocolate cake?
Moisture retention in a 4 layer chocolate cake depends on proper baking, syrup application, and storage. Avoid overbaking; remove the cakes when a toothpick shows moist crumbs, not when fully dry. Overbaking evaporates internal moisture and produces a tight crumb. The cocoa syrup brushed between layers plays a critical functional role by reintroducing moisture and enhancing chocolate intensity without making the structure soggy.
Apply syrup evenly with a pastry brush, ensuring full but controlled coverage. Additionally, wrapping cooled layers promptly prevents moisture loss before assembly. Once assembled, refrigerate the 4 layer chocolate cake to stabilize the ganache, but always bring it close to room temperature before serving to restore softness in both crumb and frosting. Proper fat ratio from oil also contributes to prolonged tenderness compared to butter-based cakes.
How should I store leftovers?
Place slices in an airtight container or cover the cut surface tightly with plastic wrap to prevent drying and absorption of refrigerator odors. Properly stored, the cake will maintain quality for up to four days. Before serving, allow slices to sit at room temperature for 20 to 30 minutes to soften the ganache and restore optimal texture.
For longer storage, wrap individual slices tightly in plastic wrap and then foil, and freeze for up to one month. Thaw overnight in the refrigerator before bringing to room temperature. Avoid repeated temperature fluctuations, as condensation can affect surface texture and overall quality of the 4 layer chocolate cake.
What type of chocolate works best for the ganache?
For a balanced ganache in a 4 layer chocolate cake, use dark chocolate containing 60 to 70 percent cacao. This range provides sufficient cocoa solids for structure while maintaining smooth meltability and controlled sweetness. Chocolate below 55 percent cacao may produce an overly sweet, softer ganache, while chocolate above 75 percent can create excessive firmness and bitterness unless the cream ratio is adjusted.
Use high-quality baking chocolate or couverture rather than chocolate chips, which often contain stabilizers that inhibit proper melting. Finely chopping the chocolate ensures uniform melting when hot cream is added. Maintaining the correct cream-to-chocolate ratio is critical for spreadable consistency; altering cacao percentage without adjusting fat and liquid balance can change viscosity and stability in the finished 4 layer chocolate cake.
How should I slice and serve a 4 layer chocolate cake cleanly?
Refrigerate at least one hour after frosting to stabilize the layers. Use a long, sharp knife dipped in hot water and wiped dry before each cut. The heat allows the blade to glide through the ganache without dragging or compressing the crumb. Wipe the knife clean between slices to prevent buildup that can smear layers.
For precise portions, score the top lightly before cutting fully through. Allow slices to sit at room temperature for 15 to 20 minutes before serving to soften the ganache slightly and improve mouthfeel.
Can I make this 4 layer chocolate cake in different pan sizes?
The recipe is calibrated for two 9-inch round pans per batch. If using 8-inch pans, the layers will be slightly thicker and may require an additional 5 to 10 minutes of baking time. Always test for doneness using the spring-back method and a toothpick with moist crumbs.
For 10-inch pans, the layers will be thinner and may bake 5 to 8 minutes faster. Do not fill pans more than two-thirds full to prevent overflow. If using rectangular pans, calculate volume to maintain equivalent batter depth.
How do I know when the ganache is the right consistency?
The ganache for a 4 layer chocolate cake should be thick, smooth, and spreadable, similar to soft peanut butter. It must hold its shape when spread but still glide easily across the surface without tearing the cake crumb. If it is too fluid, it will squeeze out between layers and cause structural instability.
If too firm, it will be difficult to spread evenly and may create air pockets. After chilling, stir the ganache to assess consistency. If overly firm, allow it to sit at room temperature for 10 to 20 minutes, stirring occasionally. If too soft, refrigerate in short intervals, stirring between each.
Can this 4 layer chocolate cake be made dairy-free?
Replace whole milk with an equal amount of unsweetened almond milk, oat milk, or soy milk. Ensure the alternative milk is neutral in flavor and unsweetened to maintain balance. For the ganache, substitute heavy cream with full-fat canned coconut milk, using the same volume.
The chocolate must be dairy-free dark chocolate without milk solids. Replace unsalted butter in the ganache with a neutral dairy-free butter alternative or omit it entirely, understanding that butter contributes shine and smoothness. The final flavor profile may have subtle coconut undertones if using coconut milk.
Can I turn this 4 layer chocolate cake into cupcakes?
This batter can be used for cupcakes, though the yield and bake time will change. Fill standard cupcake liners about two-thirds full to allow proper rise. Bake at 325°F/165°C for approximately 18 to 22 minutes, checking for doneness when the tops spring back lightly and a toothpick shows moist crumbs. This recipe yields approximately 24 to 30 cupcakes per batch, depending on portion size.
The ganache can be whipped slightly after chilling to create a pipeable frosting consistency. Because cupcakes lack syrup-brushed layers, consider brushing the tops lightly with cocoa syrup before frosting to replicate the moisture profile of the full 4 layer chocolate cake. Monitor closely to avoid overbaking, as smaller portions dry out faster than full cake layers.
Why is hot water added to the batter?
Hot water serves a functional purpose in this 4 layer chocolate cake by blooming the cocoa powder. Blooming hydrates cocoa particles, intensifies chocolate flavor, and creates a smoother batter. The heat helps dissolve cocoa solids and enhances aroma development.
Additionally, hot water thins the batter, resulting in a more fluid consistency that produces a moist, tender crumb after baking. The elevated temperature does not cook the eggs because it is incorporated gradually into a mixed batter. Skipping or reducing the hot water can lead to a denser texture and muted chocolate flavor. For best results, use freshly boiled water and mix just until incorporated.
How do I prevent the layers from sliding?
Layer stability in a 4 layer chocolate cake depends on ganache consistency, level layers, and proper chilling. The ganache must be thickened to a spreadable, frosting-like texture before assembly. If too soft, refrigerate briefly and stir until it firms. Ensure each cake layer is completely cooled and leveled with a serrated knife to create flat surfaces.
Apply ganache evenly, avoiding excessively thick filling layers that can destabilize the stack. After stacking two layers, chill for 15 to 20 minutes to help set structure before continuing. Once fully assembled, refrigerate at least one hour before final slicing. If transporting the cake, keep it chilled and place it on a non-slip cake board.
Can I add coffee to enhance the flavor of this 4 layer chocolate cake?
Coffee is a highly effective flavor enhancer in a 4 layer chocolate cake because it intensifies cocoa depth without making the cake taste like coffee. The simplest method is replacing the hot water with hot brewed coffee at equal volume. This preserves hydration while amplifying chocolate complexity through complementary bitter notes.
Alternatively, dissolve 1 to 2 teaspoons of instant espresso powder into the hot water before adding it to the batter. Coffee works synergistically with cocoa by highlighting roasted flavor compounds. It does not alter structure when substituted properly. Avoid reducing total liquid volume, as hydration is critical to maintaining the moist crumb characteristic of this 4 layer chocolate cake.
