  • 1 ½ tsp baking powder
  • 1 ½ tsp baking soda
  • 1 tsp salt
  • 2 large eggs
  • 1 cup whole milk

Step-by-Step Instructions

Let’s get started on this chocolate masterpiece!

Prepare the Chocolate Cake

  1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour three 8-inch round cake pans, or line the bottoms with parchment paper.
  2. Mix the Dry Ingredients: In a large bowl, sift together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
  3. Add Wet Ingredients: Add the eggs, milk, vegetable oil, and vanilla extract to the dry ingredients. Use a mixer on medium speed until everything is smooth and well combined.
  4. Add the Boiling Water: Carefully pour in the boiling water, mixing until just combined. The batter will be very thin, but that’s what makes the cake so moist.
  5. Bake the Cakes: Divide the batter evenly between the three prepared cake pans. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
  6. Cool the Cakes: Let the cakes cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.

the Chocolate Mousse Filling

  1. Melt the Chocolate: Place the chopped semi-sweet chocolate in a heatproof bowl. In a small saucepan, heat 1 cup of heavy cream over medium heat until it just begins to simmer. Pour the cream over the chopped chocolate and let it sit for 1 minute.
  2. Mix: Stir until the chocolate is completely melted and smooth. Let the mixture cool to room temperature.
  3. Whip the Cream: In a separate bowl, whip 1 cup of heavy cream with 2 tbsp of sugar until stiff peaks form.
  4. Combine: Gently fold the whipped cream into the cooled chocolate mixture until smooth and fluffy.

Prepare the Chocolate Ganache

  1. Heat the Cream: In a small saucepan, heat 1 cup of heavy cream over medium heat until it begins to simmer.
  2. Make the Ganache: Pour the hot cream over the chopped dark chocolate and let it sit for 1 minute. Stir until smooth and glossy.
  3. Add Butter: Stir in the butter for extra shine and richness. Let it cool for a few minutes before pouring it over the cake.

Assemble the Cake

  1. Layer the Cake: Place the first cake layer on a cake stand or platter. Spread half of the chocolate mousse evenly over the top.
  2. Add the Second Layer: Place the second cake layer on top and spread the remaining mousse on top.
  3. Top with the Third Layer: Place the third cake layer on top, pressing gently to ensure the layers are even.
  4. Pour the Ganache: Pour the ganache over the top of the cake, allowing it to drip down the sides for a beautiful, glossy finish

How to Serve

  • Serve in Slices: Cut the cake into 10-12 slices. Each slice is rich and decadent, so you don’t need large portions to enjoy.
  • Pair with a Beverage: Serve the cake with a glass of red wine, milk, or a hot cup of coffee to complement the deep chocolate flavor.
  • Garnish: Garnish with chocolate shavings, berries, or a dusting of powdered sugar for a decorative touch.

Additional Tips

  • Cake Storage: Store leftovers in an airtight container in the fridge for up to 3 days.
  • Make Ahead: You can prepare the cake layers a day in advance and refrigerate them. The mousse and ganache can also be made ahead and stored in the fridge until ready to assemble.
  • Freeze for Later: If you want to freeze the cake, wrap each layer tightly in plastic wrap and foil before freezing. Thaw in the fridge before assembling.

Recipe Variations

  • Espresso Infused Cake: Add 1-2 tsp of instant espresso powder to the cake batter for a subtle coffee flavor that enhances the chocolate.
  • Add Berries: For a fresh contrast, add a layer of fresh raspberries or strawberries between the cake layers.
  • White Chocolate Mousse: Swap the semi-sweet chocolate for white chocolate in the mousse for a different flavor profile.

FAQ Section

If you have any questions about making this Triple Chocolate Layer Cake, you’re not alone! Here are some frequently asked questions to help you out. From ingredient substitutions to cake storage, I’ve got you covered with all the details.

  • Can I use milk chocolate instead of dark chocolate for the ganache? Yes, you can! Keep in mind that milk chocolate will result in a sweeter ganache.
  • Can I use a different cake size? If you want to use 9-inch pans instead of 8-inch, the baking time will be slightly shorter. Keep an eye on the cakes as they bake.
  • Can I make this cake without the mousse? You can, but the mousse adds a luxurious texture. If you prefer, you can fill the layers with more ganache or a different frosting.
