Ingredients Needed for Double Chocolate Cake
- Flour: Gives the cake its structure while keeping it light. All-purpose flour works perfectly here.

- Baking powder and baking soda: A combo of these two ensures the cake rises beautifully while staying tender.
- Sugar: Sweetens the cake while helping to lock in moisture.
- Eggs: Bind everything together and add richness to the cake.
- Buttermilk: Adds tanginess and keeps the cake super moist.
- Brewed coffee: Enhances the chocolate flavor without tasting like coffee.
- Vanilla extract: Balances the flavors and rounds everything out.
- Vegetable oil: Keeps the cake soft and moist for days.

- Chocolate chips, heavy cream, and butter: The holy trinity of ganache—rich, creamy, and decadent.
How to make Double Chocolate Cake
**For more detailed instructions, please refer to the printable recipe card below.**
Combine the dry ingredients in one bowl and whisk the wet ingredients in another.
Gradually add the wet ingredients to the dry, mixing just until combined.
Divide the batter evenly between the pans and bake until the cakes are set but still moist.
Cool the cakes, remove the dome tops, and slice in half to make 4 layers.
Make the ganache by pouring hot cream over chocolate chips and butter, then letting it cool to a spreadable consistency.
Assemble the layers with ganache in between.
Apply a thin crumb coat over the entire cake to seal in any loose crumbs, then refrigerate for 5 minutes to set.
Add the final layer of frosting outside with the remaining ganache and decorate.
Variations
- Peanut Butter Dream:
Spread a thin layer of creamy peanut butter between each cake layer before adding the ganache. The peanut butter pairs perfectly with the rich chocolate, creating that classic combo everyone loves. For extra indulgence, sprinkle some crushed peanuts on top of the ganache for added texture. - Mint Chocolate Cake:
Stir 1/2 teaspoon of peppermint extract into the ganache for a refreshing, cool flavor. This twist adds a holiday vibe to your cake, but it’s also great year-round for anyone who loves mint and chocolate together. Garnish with crushed candy canes or mint leaves for a decorative touch. - Black Forest Cake:
Spread a layer of cherry jam or fresh, pitted cherries between each cake layer to balance the chocolate richness with fruity tartness. Add a dollop of whipped cream on top for a classic Black Forest presentation, and sprinkle some shaved chocolate over the top for an extra flourish. - Salted Caramel Chocolate Cake:
Drizzle salted caramel sauce over the ganache in each layer for a sweet and salty combination. The caramel enhances the chocolate flavor beautifully. You can even mix a bit of the caramel into the ganache for a fully integrated flavor. Sprinkle a touch of flaky sea salt over the finished cake for that perfect salty-sweet bite. - Espresso Infusion:
Swap the brewed coffee in the batter with strong espresso to amplify the mocha flavor in the cake. You can also stir a teaspoon of espresso powder into the ganache for an extra layer of richness. Garnish with chocolate-covered espresso beans for a fancy finish.
Serving Suggestions
- With Whipped Cream:
Add a generous dollop of freshly whipped cream on the side of each slice. The light and airy cream balances out the cake’s richness, giving you a perfectly harmonious bite every time. - Topped with Fresh Berries:
Serve each slice with a handful of fresh raspberries, strawberries, or blackberries. Their bright, tart flavor cuts through the chocolate and adds a beautiful pop of color to your plate. - With a Scoop of Ice Cream:
Pair the cake with a scoop of vanilla, coffee, or salted caramel ice cream. The cold, creamy texture is the ultimate complement to the warm, rich chocolate flavors. - Drizzled with White Chocolate:
Melt white chocolate and drizzle it in an elegant pattern over the cake before serving. It adds a touch of sweetness and looks absolutely stunning for special occasions. - For a Party Centerpiece:
Decorate the top of the cake with candles, sprinkles, or edible gold leaf for a party-worthy presentation. Place it on a cake stand, and let it be the star of the dessert table.
Storage and Freezing
- How should I store Double Chocolate Cake?
Store the cake in an airtight container or tightly wrapped in plastic wrap to keep it fresh. Refrigerate for up to 5 days. If you’ve cut into the cake, press a piece of plastic wrap directly onto the exposed sides to lock in moisture. Before serving, let it sit at room temperature for about 20 minutes for the best texture.
- Can I freeze Double Chocolate Cake?
To freeze, wrap individual slices tightly in plastic wrap, then place them in a freezer-safe container or zip-top bag. This prevents freezer burn and keeps the cake fresh for up to 3 months. When you’re ready to enjoy, thaw slices overnight in the fridge or at room temperature for about 30 minutes before serving.

Tips & Tricks
- Use room-temperature ingredients:
Cold eggs, buttermilk, or sour cream can cause the batter to curdle or not mix evenly. Let everything come to room temperature before starting for a smoother batter and a fluffier cake. - Chill the cake layers:
Refrigerating the cakes before slicing and assembling makes them firmer and easier to handle. This step also prevents crumbs from breaking loose and makes your frosting look cleaner. - Don’t overbake:
Take the cakes out when a toothpick comes out with moist crumbs attached. If it’s completely clean, the cake may already be overbaked. Every oven is a little different, so start checking a few minutes early to avoid dryness. You want this cake to be moist. - Level the layers:
If your cakes come out with domed tops, trim them with a serrated knife. This ensures even stacking and keeps the layers stable. A turntable makes this easier, but a steady hand works too! - Let the ganache thicken:
Be patient and let the ganache cool until it’s thick but spreadable, like buttercream. If it’s too runny, it will seep out between the layers. Chill it briefly if needed but keep an eye on it so it doesn’t harden completely.

Rich & Moist Double Chocolate Layer Cake
Equipment
- Whisk or Mixer
- Two 8-inch round cake pans
- Parchment paper
- Cooling rack
- Saucepan
Ingredients
For the Cake:
- 3 cups all-purpose flour
- ¾ cup unsweetened cocoa powder Dutch-processed preferred
- 2 teaspoons baking powder
- 1 ½ teaspoons baking soda
- 1 teaspoon salt
- 1 ½ cups granulated sugar
- 3 large eggs room temperature
- 1 cup buttermilk
- ½ cup brewed coffee cooled
- 2 teaspoons vanilla extract
- ½ cup vegetable oil
- ½ cup sour cream
For the Ganache:
- 4 cups semi-sweet chocolate chips
- 2 cups heavy cream
- 4 tablespoons unsalted butter
- 2 teaspoons vanilla extract
Instructions
For the Cake:
- Preheat your oven to 350°F (175°C). Grease and line two 8-inch round cake pans with parchment paper. (Alternatively, use four 8-inch pans for quicker cook time or two 9-inch pans for a 2-layer cake.)
- In a large bowl, whisk together the flour, cocoa powder, baking powder, baking soda, salt, and sugar.
- In another bowl, whisk the eggs, buttermilk, brewed coffee, vanilla extract, oil, and sour cream until smooth.
- Gradually add the wet ingredients to the dry ingredients, stirring until just combined. Avoid overmixing to keep the cake tender.
- Divide the batter evenly between the prepared pans. Bake for 35–40 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs clinging to it but no wet batter. Avoid waiting until the toothpick comes out completely clean, as this can lead to a dry cake.
- Cool the cakes in the pans for 10 minutes. Remove the cakes from the pans, wrap them tightly in cling wrap, and place them back into the cooled pans. Refrigerate for 30 minutes to make them easier to work with.
- To reduce any domed tops, stack the cakes on top of each other while chilling, alternating every 15 minutes, and gently press down on the domes.
- After chilling, trim the domes with a knife to create flat, even layers. Cut each cake in half horizontally to make 4 layers.
For the Ganache:
- Heat the heavy cream and butter in a saucepan over medium heat until steaming but not boiling.
- Pour the hot cream mixture over the chocolate chips in a bowl. Let sit for 1–2 minutes, then stir until smooth and glossy.
- Stir in the vanilla extract. Let the ganache cool at room temperature for 30 minutes, then refrigerate for an additional 30 minutes. The ganache should thicken to a spreadable, buttercream-like consistency. Check frequently to ensure it doesn’t harden too much.
Assembly:
- Place one cake layer on a serving plate or cake stand. *** See Notes Below***
- Spread about 1/4 of the ganache evenly over the top of the first layer. Place the second cake layer on top and repeat the process with the next two layers, spreading ganache evenly between each layer. Finish by placing the final cake layer on top, ready for the crumb coat. *** See Notes Below***
- Apply a thin crumb coat of ganache over the entire cake to trap crumbs. Chill for 5 minutes to set.
- Use the remaining ganache to frost the top and sides of the cake evenly. Smooth it with an offset spatula.
- If you have leftover ganache you can add swirls of on top and chocolate sprinkles around the bottom. I used Walton M1 Piping nozzle and frosting bag.
