Gluten-free chocolate mousse cakes pair a silky, airy chocolate mousse with a thin, light chocolate cake base. Elegant and indulgent, these individual domes are perfect for a romantic dessert or any special occasion when you want something that looks impressive but is surprisingly approachable to make at home.

I first saw these domed cakes on Julia Baker’s show Sweet Julia, where she called them Francois Premiers. I made them years ago and loved the concept, but I changed the original gooey flourless brownie base to a lighter chocolate joconde sponge. The brownie is delicious, but I find the joconde balances the rich mousse better, giving each bite lift and texture rather than heaviness.
The Ingredients You’ll Need
The Mousse
- Chopped semi-sweet chocolate
- Heavy cream
The Joconde Cake
- Almond flour
- Powdered sugar
- Gluten-free flour blend (a good quality store-bought blend or your preferred homemade blend)
- Whole eggs
- Egg whites
- Granulated sugar
- Melted butter
- Cocoa powder
The Ganache
- Chopped milk chocolate (or semi-sweet if you prefer)
- Heavy cream
Breaking Down the Steps
These domes look professional but are straightforward if you follow the steps in order. The process breaks down into three parts: bake the joconde sponge, make and set the chocolate mousse in half-sphere molds, then glaze with a glossy ganache.
Make the Cake
- Sift almond flour, powdered sugar, and gluten-free flour to remove lumps and ensure an even texture.
- Combine the five whole eggs with the dry ingredients and blend until smooth.
- Whip the egg whites with the granulated sugar to firm peaks and gently fold the meringue into the batter to keep it airy.
- Whisk the cocoa into the melted butter and fold into the batter until fully incorporated.
- Spread the batter thinly and evenly on a prepared baking sheet and bake until the cake springs back lightly.
- Cool the cake, sprinkle a thin layer of granulated sugar on top, wrap with plastic wrap, and refrigerate overnight — this helps the cake stay moist and easier to cut cleanly.
- Use a small round cookie or biscuit cutter to cut rounds sized to fit your half-sphere molds.
Prepare the Chocolate Mousse
- Heat the cream just to boiling and pour it over the chopped chocolate. Let sit a minute, then stir from the center outward until the mixture is smooth and glossy — this creates a simple chocolate ganache base for the mousse.
- Let the chocolate mixture cool to room temperature, then whip the remaining cream to soft peaks and fold it into the cooled ganache to create a light mousse.
- Pipe or spoon the mousse into half-sphere silicone molds, filling each mold three-quarters full.
- Top each mousse dome with a round of the chilled joconde, pressing gently so it adheres to the mousse.
- Cover the molds with plastic wrap and freeze for at least six hours or overnight until fully solid.
Make the Ganache
- When the domes are fully frozen, unmold them carefully and place them on a wire rack set over parchment or a baking sheet to catch drips.
- Heat heavy cream to a gentle boil and pour it over the chopped chocolate for the glaze. Cover briefly, then stir until the ganache is smooth and glossy.
- Pour the warm ganache over the frozen domes, covering them completely for a smooth finish. If you like, add delicate decorations such as gold leaf or sprinkles before the glaze sets.
- Transfer finished cakes to the refrigerator to thaw briefly before serving — about 20–30 minutes so they are soft but still chilled.
Chocolate Mousse Cake FAQs
Absolutely. If you prefer a flourless brownie or a thin chocolate cake, both work well. The original recipe uses a gooey flourless brownie; if you use brownies, bake them in a shallow pan so the rounds are thin. A regular chocolate cake can also be used, though the texture and balance will differ slightly from the joconde sponge.
You can line small bowls or a muffin tin with plastic wrap and shape domes that way. The finished shape won’t be a perfect hemisphere, but the flavors and textures will still be excellent.
Once glazed and fully assembled, store the cakes in the refrigerator for 3–4 days. If you want to prepare ahead, keep the mousse domes frozen in their molds for up to a month and glaze them just before serving.
