How to Make Decadent Triple-Layer Chocolate Mousse Cake

Follow these simple steps to prepare this delicious Decadent Triple-Layer Chocolate Mousse Cake:

Step 1: Preheat the Oven
Preheat your oven to 350℉ (175℃) and grease and line your baking pans with parchment paper to ensure easy removal later.

Step 2: Prepare Dry Ingredients
In a large bowl, whisk together the all-purpose flour, granulated sugar, dark cocoa powder, unsweetened cocoa powder, baking soda, baking powder, and salt until well combined.

Step 3: Mix Wet Ingredients
In another bowl, combine the vegetable oil, sour cream, eggs, and vanilla extract until it is smooth. Gradually add the buttermilk and mix until everything is well incorporated.

Step 4: Combine Mixtures
Add the dry mixture to the wet ingredients, mixing until just combined. Then, carefully stir in the hot coffee or water to the batter until smooth and silky.

Step 5: Bake the Cakes
Pour the batter into your prepared pans. Bake a 9×13-inch pan for about 30 to 40 minutes or two round pans for 23 to 26 minutes, until a toothpick inserted into the center comes out clean.

Step 6: Cool and Prepare the Mousse
Let your cakes cool on wire racks. While they’re cooling, whisk together the hot water and cocoa powder for the mousse. Melt the chopped chocolate in a double boiler or a microwave until smooth. Mix the melted chocolate with the cocoa-water mixture until fully combined.

Finish by folding whipped heavy cream, powdered sugar, and vanilla into the chocolate mixture. Refrigerate until firm.

Step 7: Make the Ganache
Place chopped chocolate in a bowl. Heat the heavy cream until it simmers, then pour it over the chocolate and let it sit for 2-3 minutes to melt. Stir until smooth, then allow to cool for about 20 minutes.

Step 8: Assemble the Cake
Carefully layer the cake by placing mousse between your chocolate cake layers and topping the whole cake with ganache. Garnish with chocolate curls, sprinkles, or fresh fruit as desired.

Finally, serve immediately or chill for 4–6 hours to let the flavors meld beautifully. When it’s time to indulge, prepare for the gasps and ooohs as forks dive into this irresistible treat!
