🍰 Step-by-Step Instructions

Step 1: Bake the Chocolate Cake Base

  1. Preheat oven to 350°F (175°C). Grease and line the bottom of a 9-inch springform pan with parchment.

  2. In a bowl, whisk together flour, cocoa powder, baking powder, and salt.

  3. In a separate bowl, beat eggs and sugar until light and fluffy. Stir in oil, milk, and vanilla.

  4. Add dry ingredients to wet and mix until just combined.

  5. Pour batter into prepared pan and bake for 18–22 minutes or until a toothpick comes out clean.

  6. Let cool completely in the pan.

Step 2: Make the Milk Chocolate Mousse

  1. Melt milk chocolate in a double boiler or microwave in 30-second intervals. Let cool slightly.

  2. In a chilled bowl, beat the cream and powdered sugar to soft peaks.

  3. Fold a small amount of whipped cream into the melted chocolate to lighten it, then gently fold in the rest.

  4. Spread evenly over the cooled cake base in the springform pan. Smooth the top and refrigerate for 30 minutes to set.

Step 3: Make the White Chocolate Mousse

  1. Repeat the same process: melt white chocolate and cool slightly.

  2. Whip cream and powdered sugar to soft peaks.

  3. Fold whipped cream into white chocolate as above.

  4. Spoon over the milk chocolate mousse layer. Smooth the top and refrigerate for at least 4 hours or until fully set.

Step 4: Decorate and Serve

  • Once fully chilled and set, remove the cake from the springform pan.

  • Garnish with chocolate curls, shavings, cocoa powder, or fresh berries.

  • Slice with a hot knife for clean edges and serve chilled.

🧊 Make Ahead + Storage Tips

  • Make Ahead: Best made a day ahead to allow layers to set perfectly.

  • Leftover Slices: Store individual slices in airtight containers.

❓ Frequently Asked Questions

Can I use all dark chocolate?
Of course! Just swap each layer’s chocolate to your preference. You could even do all dark, or a dark-milk combo.

Is gelatin necessary for stability?
Nope—thanks to the cooled melted chocolate and whipped cream, the mousse sets beautifully on its own.

Can I make this in a regular cake pan?
A springform pan is ideal for clean layering and easy release, but a deep cake pan lined with plastic wrap can work in a pinch.

Can I add a cookie crust instead of cake?
Absolutely! A crushed Oreo or chocolate graham crust makes a delicious base.
