Doberge Cake: A Step-by-Step Guide to Mastering this New Orleans Classic

The Doberge cake, a New Orleans institution, isn’t just a dessert; it’s a testament to patience, skill, and the enduring power of deliciousness. This multi-layered cake, typically featuring six thin layers of cake alternating with custard and covered in a luscious buttercream or chocolate ganache, might seem daunting at first. However, with this detailed guide, you’ll be well on your way to creating your own show-stopping Doberge cake.

What is Doberge Cake? A Brief History

The Doberge cake’s origins trace back to the late 19th century, when a baker named Beulah Ledner adapted the Hungarian Dobos torte for New Orleans palates. The Dobos torte, known for its thin layers of sponge cake and chocolate buttercream, was transformed into a lighter, more custardy version, reflecting the city’s love for rich flavors and elegant desserts. Today, Doberge cake remains a beloved tradition in New Orleans, often served at special occasions and celebrations.

The Key to Doberge Success: Patience and Precision

Before diving into the recipe, it’s important to understand that making a Doberge cake requires time and attention to detail. The thin cake layers need to be baked carefully to prevent them from drying out, and the custard must be smooth and creamy. Don’t be discouraged if your first attempt isn’t perfect; practice makes perfect, and the reward of a homemade Doberge cake is well worth the effort.

The Classic Doberge Cake Recipe: Chocolate Custard and Chocolate Buttercream

This recipe focuses on the classic chocolate Doberge cake, featuring chocolate custard filling and chocolate buttercream frosting. However, feel free to experiment with other flavors like lemon, caramel, or even strawberry. The basic principles remain the same, regardless of the flavor variations.

Ingredients:

For the Cake Layers:

• 2 1/2 cups all-purpose flour
• 2 cups granulated sugar
• 1 teaspoon baking powder
• 1 teaspoon baking soda
• 1 teaspoon salt
• 1 cup buttermilk
• 1/2 cup (1 stick) unsalted butter, softened
• 1/2 cup vegetable oil
• 2 large eggs
• 2 teaspoons vanilla extract
• 1 cup hot coffee

For the Chocolate Custard Filling:

• 4 large egg yolks
• 3/4 cup granulated sugar
• 1/4 cup cornstarch
• 1/4 teaspoon salt
• 2 cups whole milk
• 6 ounces bittersweet chocolate, finely chopped
• 2 tablespoons unsalted butter
• 1 teaspoon vanilla extract

For the Chocolate Buttercream Frosting:

• 1 cup (2 sticks) unsalted butter, softened
• 3 cups powdered sugar
• 1/2 cup unsweetened cocoa powder
• 1/4 cup milk
• 1 teaspoon vanilla extract
• Pinch of salt

Equipment:

• 6 (8-inch) cake pans (or bake in batches)
• Parchment paper
• Mixer (stand or hand-held)
• Whisk
• Saucepan
• Double boiler or heatproof bowl
• Offset spatula
• Cake decorating turntable (optional)

Instructions:

Part 1: Making the Cake Layers

1. Preheat and Prepare: Preheat oven to 350°F (175°C). Grease and flour six 8-inch cake pans. Line the bottoms with parchment paper rounds. This is crucial for easy removal of the delicate layers.
2. Combine Dry Ingredients: In a large bowl, whisk together flour, sugar, baking powder, baking soda, and salt. Make sure everything is evenly distributed.
3. Combine Wet Ingredients: In a separate bowl, cream together the softened butter, vegetable oil, and sugar until light and fluffy using a mixer. Beat in the eggs one at a time, then stir in the vanilla extract.
4. Alternate Wet and Dry: Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk, beginning and ending with the dry ingredients. Beat until just combined. Do not overmix. Overmixing will result in a tough cake.
5. Add Hot Coffee: Slowly pour in the hot coffee and mix until well combined. The batter will be thin. This is normal. The coffee enhances the chocolate flavor.
6. Divide the Batter: Divide the batter evenly among the prepared cake pans. A kitchen scale is helpful for ensuring even layers. Aim for roughly the same amount of batter in each pan.
7. Bake: Bake for 12-15 minutes, or until a toothpick inserted into the center comes out clean. The edges should be lightly golden brown. Watch carefully, as the thin layers can burn easily.
8. Cool: Let the cakes cool in the pans for 10 minutes before inverting them onto a wire rack to cool completely. Remove the parchment paper. Ensure the layers are completely cool before frosting.

Part 2: Making the Chocolate Custard Filling

1. Whisk Egg Yolks and Sugar: In a medium bowl, whisk together egg yolks, sugar, cornstarch, and salt until pale and smooth. This mixture will help thicken the custard.
2. Heat Milk: In a saucepan, heat the milk over medium heat until it just begins to simmer. Do not boil.
3. Temper the Egg Yolks: Gradually pour a small amount of the hot milk into the egg yolk mixture, whisking constantly to prevent the eggs from curdling. This process is called tempering.
4. Combine and Cook: Pour the tempered egg yolk mixture back into the saucepan with the remaining milk. Cook over medium heat, stirring constantly, until the mixture thickens and coats the back of a spoon. This should take about 5-7 minutes. Be patient and continue stirring to prevent scorching.
5. Add Chocolate and Butter: Remove from heat and stir in the finely chopped chocolate and butter until melted and smooth.
6. Add Vanilla: Stir in the vanilla extract.
7. Cool: Pour the custard into a bowl, cover with plastic wrap (pressing the plastic wrap directly onto the surface of the custard to prevent a skin from forming), and refrigerate for at least 2 hours, or until completely cold. The custard will thicken further as it cools.

Part 3: Making the Chocolate Buttercream Frosting

1. Cream Butter: In a large bowl, beat the softened butter with a mixer until light and fluffy.
2. Add Powdered Sugar and Cocoa: Gradually add the powdered sugar and cocoa powder, beating on low speed until combined.
3. Add Milk and Vanilla: Gradually add the milk and vanilla extract, beating on medium speed until light and fluffy. Add a pinch of salt to balance the sweetness.
4. Adjust Consistency: If the frosting is too thick, add a little more milk, one tablespoon at a time. If it’s too thin, add a little more powdered sugar.

Part 4: Assembling the Doberge Cake

1. Level the Cake Layers (Optional): If your cake layers are uneven, use a serrated knife to level them. This will ensure a more even and professional-looking cake.
2. Place First Layer: Place one cake layer on a cake plate or serving platter.
3. Spread Custard: Spread a generous layer of chocolate custard over the first cake layer. Make sure the custard is evenly distributed.
4. Repeat Layers: Repeat with the remaining cake layers and custard, ending with a cake layer on top. You should have six layers of cake and five layers of custard.
5. Crumb Coat: Spread a thin layer of chocolate buttercream over the entire cake to seal in any crumbs. This is called a crumb coat.
6. Chill: Refrigerate the cake for at least 30 minutes to allow the crumb coat to set. This will make it easier to frost the final layer.
7. Frost the Cake: Frost the entire cake with the remaining chocolate buttercream, using an offset spatula to create a smooth and even finish.
8. Decorate (Optional): Decorate the cake as desired. You can use chocolate shavings, sprinkles, or a simple swirl of buttercream.
9. Chill: Refrigerate the cake for at least 1 hour before serving to allow the frosting to set.

Tips for Success

• Use Room Temperature Ingredients: Room temperature butter and eggs will cream together more easily, resulting in a smoother batter and a more tender cake.
• Don’t Overmix: Overmixing the cake batter will develop the gluten, resulting in a tough cake. Mix until just combined.
• Use a Kitchen Scale: Using a kitchen scale to measure the batter for each cake layer will ensure that they are all the same thickness.
• Cool Cakes Completely: Make sure the cake layers are completely cool before frosting. Otherwise, the frosting will melt.
• Chill the Cake: Chilling the cake after each step (crumb coat and final frosting) will make it easier to work with and will help the frosting set.
• Be Patient: Making a Doberge cake takes time and patience. Don’t rush the process.

Flavor Variations

While the classic chocolate Doberge cake is a beloved favorite, don’t be afraid to experiment with other flavors. Here are a few ideas:

• Lemon Doberge Cake: Use lemon curd as the filling and lemon buttercream as the frosting.
• Caramel Doberge Cake: Use caramel custard as the filling and caramel buttercream as the frosting.
• Strawberry Doberge Cake: Use strawberry jam or fresh strawberries as the filling and strawberry buttercream as the frosting.
• Coconut Doberge Cake: Use coconut custard as the filling and coconut buttercream as the frosting.

Serving and Storing

Doberge cake is best served chilled. It can be stored in the refrigerator for up to 3 days. Because of the custard filling, it is important to keep it refrigerated to prevent spoilage. To prevent the cake from drying out, cover it tightly with plastic wrap or store it in an airtight container.

Troubleshooting

• Cake Layers are Dry: Make sure you are not overbaking the cake layers. Bake them just until a toothpick inserted into the center comes out clean. Also, make sure you are using enough liquid in the batter.
• Custard is Lumpy: Make sure you are whisking the egg yolk mixture constantly while cooking to prevent the eggs from curdling. If the custard does become lumpy, you can try straining it through a fine-mesh sieve.
• Buttercream is Too Soft: Make sure your butter is at room temperature, but not too soft. If the buttercream is too soft, refrigerate it for 15-20 minutes before using.
• Cake is Sliding: Make sure the custard and buttercream are properly chilled before assembling the cake. This will help to prevent the layers from sliding.
