Ingredients:

• 1/2 cup (60g) unsweetened cocoa powder
• 1 teaspoon baking powder
• 1/4 teaspoon salt
• 1/2 cup (115g) unsalted butter, softened
• 1 cup (200g) granulated sugar
• 2 large eggs
• 1 teaspoon vanilla extract
• 1/2 cup (120ml) buttermilk

For the Chocolate Mousse:

• 8 ounces (225g) bittersweet chocolate, finely chopped
• 1/4 cup (60ml) strong brewed coffee
• 1 tablespoon rum (optional)
• 1 1/4 cups (300ml) heavy cream, chilled
• 1/4 cup (30g) powdered sugar

For the Chocolate Ganache:

• 4 ounces (110g) bittersweet chocolate, finely chopped
• 1/2 cup (120ml) heavy cream
• 1 tablespoon unsalted butter

Equipment:

• Two 9-inch round cake pans
• Parchment paper
• Two mixing bowls
• Electric mixer
• Rubber spatula
• Saucepan
• Whisk
• Serrated knife
• Offset spatula (optional)

Instructions:

Making the Sponge Cake:

1. Preheat oven to 350°F (175°C). Grease and line the bottoms of two 9-inch round cake pans with parchment paper.
2. In a medium bowl, whisk together the flour, cocoa powder, baking powder, and salt.
3. In a separate large bowl, cream together the softened butter and sugar until light and fluffy using an electric mixer. Beat in the eggs one at a time, then stir in the vanilla extract.
4. Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk, beginning and ending with the dry ingredients. Mix until just combined, being careful not to overmix.
5. Divide the batter evenly between the prepared cake pans.
6. Bake for 25-30 minutes, or until a wooden skewer inserted into the center comes out clean.
7. Let the cakes cool in the pans for 10 minutes before inverting them onto a wire rack to cool completely.

Making the Chocolate Mousse:

1. Place the chopped chocolate in a heatproof bowl.
2. In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer. Pour the hot cream over the chopped chocolate and let it sit for a minute to melt. Add in the coffee and rum (if using) and whisk until smooth and glossy. Set aside to cool slightly.
3. In a separate bowl, beat the chilled heavy cream with powdered sugar using an electric mixer until stiff peaks form.
4. Gently fold one-third of the whipped cream into the cooled chocolate mixture to lighten it. Then, carefully fold in the remaining whipped cream until just combined, being careful not to deflate the mousse.

Assembling the Cake:

1. Once the cakes are completely cool, use a serrated knife to carefully level the tops if needed.
2. Place one cake layer on a serving plate or cake stand.
3. Evenly spread the chocolate mousse over the cake layer.
4. Top with the second cake layer.

Making the Chocolate Ganache:

1. Place the chopped chocolate in a heatproof bowl.
2. In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer. Pour the hot cream over the chopped chocolate, let it sit for a minute to melt, then whisk until smooth.
3. Stir in the butter until melted and fully incorporated. Let the ganache cool slightly until it thickens to a spreadable consistency.

Glazing the Cake:

1. Pour the chocolate ganache over the top of the cake, using an offset spatula or the back of a spoon to spread it evenly over the top and sides.
2. Refrigerate the cake for at least 4 hours, or preferably overnight, to allow the mousse to set and the flavors to meld.

Tips and Tricks:

• Room Temperature Ingredients: Using room temperature eggs and butter will help them emulsify better into the batter, resulting in a lighter cake.
• Don’t Overmix: Overmixing the batter can develop the gluten in the flour, leading to a tough cake. Mix just until the ingredients are combined.
• Cooling the Cake Layers: Make sure the cake layers are completely cool before assembling the cake to prevent the mousse from melting.
• Whipping the Cream: For best results, chill the heavy cream and the bowl you’ll be using before whipping. This will help the cream whip up faster and hold its shape better.
• Ganache Consistency: If your ganache is too thick, you can gently warm it up on the stovetop over low heat, stirring constantly. If it’s too thin, let it cool further at room temperature.

FAQs about Hungarian Chocolate Mousse Cake:

Can I make this cake ahead of time?

Absolutely! In fact, it’s best to make this cake at least a day in advance to allow ample time for the mousse to set and the flavors to fully develop.

What can I use as a substitute for rum?

If you don’t have rum or prefer not to use alcohol, you can easily substitute it with an equal amount of strong coffee or even water.

Can I freeze Hungarian Chocolate Mousse Cake?

While you can freeze the unfrosted cake layers, it’s not recommended to freeze the fully assembled cake as the mousse can become grainy upon thawing.
