Ingredients You’ll Need

For the Brownie Cake Base

• 8 oz bittersweet or semi-sweet chocolate, chopped or use high-quality chips
  
• 1 cup (2 sticks) unsalted butter, cut into pieces
  
• 1 cup granulated sugar
  
• 5 large eggs, room temperature
  
• 1 tbsp pure vanilla extract
  
• ¼ tsp fine salt
  
• ¼ cup gluten-free 1:1 baking flour (like Bob’s Red Mill or King Arthur)
  

For the Creamy Chocolate Mousse

• 8 oz bittersweet or semi-sweet chocolate, melted and slightly cooled
  
• 1⅓ cups powdered sugar
  
• 2 (8 oz) blocks full-fat cream cheese, softened to room temperature
  
• 2 tsp pure vanilla extract
  
• 2 cups cold heavy whipping cream (look for at least 36% fat for best texture)
  

For the Whipped Cream Topping

• ¾ cup cold heavy cream
  
• 2 tbsp powdered sugar
  
• 2 tsp pure vanilla extract
  
• Chocolate shavings or curls, for garnish (optional but stunning)
  

Tip: Use real vanilla and high-quality chocolate to make each layer shine.

Instructions

Step 1: Prepare the Fudgy Brownie Base

1. Preheat your oven to 325°F. Lightly grease a 10-inch springform pan with non-stick spray.
   
2. In a microwave-safe bowl, melt the butter and chocolate in 15-second bursts, stirring between each, until smooth.
   
3. Whisk in the sugar, vanilla extract, and salt.
   
4. Add the eggs one at a time, whisking well after each addition until fully incorporated.
   
5. Gently fold in the gluten-free flour with a rubber spatula until no streaks remain.
   
6. Pour the batter into the prepared pan. Smooth the top and bake for 30 to 35 minutes, or until a toothpick inserted in the center comes out mostly clean.
   
7. Let the cake cool completely on a wire rack before adding the mousse layer. This is essential—warm cake will melt the mousse.
   

Step 2: Create the Velvety Chocolate Mousse

1. Melt the chocolate in a microwave-safe bowl using short intervals. Stir until smooth and let it cool slightly.
   
2. In a large mixing bowl, beat the softened cream cheese and powdered sugar until smooth and lump-free.
   
3. Add in the melted chocolate and vanilla. Beat again until fully combined.
   
4. With the mixer on low, slowly stream in the cold heavy cream. Once added, increase speed to medium-high and whip until the mousse becomes light and fluffy, about 3 to 4 minutes.

Step 3: Assemble the Cake and Chill

1. Spoon the chocolate mousse onto the cooled brownie base. Use an offset spatula to spread it evenly to the edges.
   
2. Cover the cake tightly with plastic wrap or foil.
   
3. Refrigerate for at least 6 hours, or overnight. This allows the mousse to set properly and ensures clean slices.

Step 4: Garnish and Serve

1. Just before serving, whip the remaining heavy cream, powdered sugar, and vanilla together until stiff peaks form.
   
2. Spread the whipped cream over the mousse layer.
   
3. Garnish with grated chocolate or chocolate curls for a professional finish.
   
4. Run a thin knife around the edge of the pan before releasing the springform ring.
   
5. Slice using a hot, clean knife for best presentation.
   

Serving and Storage Tips

Serving Suggestions

• For the cleanest slices, use a sharp knife dipped in hot water and wiped dry between each cut.
  
• Serve chilled for the best mousse texture and contrast between layers.
  
• This cake is ideal for birthdays, dinner parties, or holidays where you want an impressive, make-ahead dessert.
  

Storage Guidelines

• Refrigeration: Keep the assembled cake covered in the fridge for up to 3 days. It holds its shape well and the mousse stays creamy.
  
• Make-Ahead: You can prepare the brownie base and mousse a day in advance. Add the whipped cream topping just before serving for the freshest presentation.
  
• Freezing: While the mousse texture may change slightly, the cake can be frozen (without whipped cream) for up to one month. Wrap tightly and thaw overnight in the fridge.

Helpful Notes

Essential Tips for Success

Use Room Temperature Cream Cheese
Softened cream cheese blends smoothly, preventing lumps in the mousse. Cold cream cheese can ruin the texture.

Don’t Rush the Cooling Process
The brownie base must be fully cooled before topping it with mousse. Even a slightly warm base can cause the mousse to melt and slide.

Choose the Right Cream
Use heavy whipping cream with at least 36% fat. Lower-fat versions may not whip properly or hold their shape in the mousse.

How to Get Clean Slices Every Time
Dip a sharp knife into hot water, then wipe it clean with a towel between each slice. This prevents dragging and gives smooth, professional-looking cuts.

Bonus Tip
For added texture, consider sprinkling crushed gluten-free cookies or nuts between the mousse and whipped cream layers.
