Gluten Free No Bake Chocolate Mousse Cake

If you need a dessert that’s gluten free and still feels fancy, this no bake chocolate mousse cake is exactly what you’re looking for.

It has two layers of mousse sitting on a chocolate cookie crust. One layer is dark chocolate, the other is white chocolate. Together they create something that tastes incredible and looks beautiful when you slice into it.

I love that this recipe doesn’t require any baking at all. You just layer everything in a springform pan and let the fridge do the work overnight.

Making it gluten free is easy here because the only ingredient you need to swap is the cookies for the crust. Everything else is naturally free of gluten, so there’s no compromise on taste or texture.

It’s a great recipe for holidays, birthdays, or anytime you want to impress people without spending all day in the kitchen.

Ingredients

For the Crust

• 2 1/2 cups Gluten Free Chocolate Sandwich Cookies, finely crushed
• 5 tbsp Unsalted Butter, melted

For the Dark Chocolate Mousse Layer

• 6 oz Dark Chocolate (70%), chopped
• 3 tbsp Unsalted Butter
• 1 1/2 cups Heavy Cream
• 3 tbsp Powdered Sugar
• 1 tsp Vanilla Extract

For the White Chocolate Mousse Layer

• 6 oz White Chocolate, chopped
• 1 1/2 cups Heavy Cream
• 2 tbsp Powdered Sugar
• 1/2 tsp Vanilla Extract

For the Topping

• Cocoa Powder, for dusting
• Chocolate Curls, for garnish

How to Make

Step 1

Mix the finely crushed gluten free chocolate sandwich cookies with the melted butter until evenly combined. Press firmly into the bottom of a 9-inch springform pan. Freeze for 15 minutes.

Step 2

For the dark chocolate mousse, melt the dark chocolate and 3 tbsp butter together in a heatproof bowl set over a pot of barely simmering water, stirring until smooth. Remove from heat and let cool to room temperature, about 15 minutes. It should feel just slightly warm, not hot.

Step 3

In a chilled bowl, whip the 1 1/2 cups heavy cream with 3 tbsp powdered sugar and 1 tsp vanilla extract until stiff peaks form. Gently fold about one third of the whipped cream into the cooled dark chocolate to lighten it.

Then fold in the remaining whipped cream until no streaks remain. Pour the dark chocolate mousse over the crust and smooth the top. Refrigerate for 30 minutes.

Step 4

For the white chocolate mousse, melt the white chocolate in a heatproof bowl over barely simmering water, stirring until smooth. Remove from heat and let cool to room temperature.

Step 5

In a separate chilled bowl, whip the 1 1/2 cups heavy cream with 2 tbsp powdered sugar and 1/2 tsp vanilla extract until stiff peaks form. Fold about one third of the whipped cream into the cooled white chocolate to lighten it.

Then fold in the remaining whipped cream until smooth and uniform.

Step 6

Spread the white chocolate mousse evenly over the set dark chocolate layer. Smooth the top with an offset spatula. Refrigerate for at least 6 hours or overnight until both layers are fully set.

Step 7

Before serving, dust the top lightly with cocoa powder and scatter chocolate curls over the surface. Release the springform ring, slice with a warm clean blade, and serve chilled.

My Tips

Let the Melted Chocolate Cool Enough Before Folding

This is the most important step in the whole recipe. If the melted chocolate is even a little too warm when you fold in the whipped cream, it will melt the cream and you’ll lose all that airy texture you just whipped in.

After you take the chocolate off the heat, give it a full 15 minutes to cool. It should feel barely warm when you touch the bottom of the bowl. If it still feels noticeably warm, wait a few more minutes.

White chocolate is even trickier because it’s thinner when melted. Make sure it’s truly at room temperature before folding. If you rush this step with either layer, you’ll end up with a dense, flat mousse instead of a light and fluffy one.

Fold in the Whipped Cream in Two Stages

The recipe says to fold one third of the whipped cream into the chocolate first, and there’s a good reason for that. That first third loosens up the chocolate so it’s closer in texture to the remaining whipped cream.

If you dump all the whipped cream in at once, the chocolate is so much thicker that you’ll have to stir way too hard to combine them. That extra mixing deflates the cream and your mousse comes out heavy instead of airy.

Use a spatula and fold gently by cutting down through the center, scooping along the bottom, and folding over the top. Keep going until you don’t see any streaks of white or dark.

Chill Your Bowls and Cream Before Whipping

Put your mixing bowls and whisk attachment in the freezer for about 10-15 minutes before you whip the cream. Cold equipment makes a big difference in how fast the cream whips and how stable the peaks hold.

Also make sure your heavy cream is very cold, straight from the fridge. If the cream or bowls are warm, you’ll have a hard time reaching stiff peaks and the mousse layers won’t set properly.

FAQ

Why do I need to fold the whipped cream into the chocolate in batches?

Folding a small amount of whipped cream in first lightens the melted chocolate so it becomes closer in texture to the remaining whipped cream. This makes the second fold much easier and helps you keep all that air you whipped in.

If you dump all the whipped cream in at once, the heavy chocolate can deflate it quickly, and you will end up with a dense layer instead of a light, airy mousse.
