Best Dark Chocolate Mousse Cake
You need to try this recipe at least once in your lifetime. Decadent, delicious, and elegant, this cake fits for real in the “best cake with chocolate mousse category.”
I was inspired by my favorite Romanian baker Ana Consulea and her recipe and made this cake for my coworker who was celebrating his 40th birthday. It was a real hit!
The cake is not difficult to make, but it does require some time. All entremets are usually made by freezing parts or all layers during the process.
Basically, this is what takes most of the time as the rest is pretty easy to make if you follow the instructions.
What tools do you need for this cake:
- A 9×3 inch cake ring to build the cake, but if you don’t have one, a 9-inch springform will also be OK. (23 cm diameter)
- A kitchen scale– This is a professional cake that requires precise measurements. I know that the average American would not even look at this recipe because it is not in cups and teaspoons, but if you really want to make this awesome cake, a small investment in a scale would not kill you.
What is inside the cake:
- The base of the cake is a 9-inch(23 cm) walnut meringue cake layer. This layer can also be called dacquoise.
- The next layer is dark chocolate mousse.
- On top of the mousse, there is a 7-inch layer walnut meringue cake that will sit in the middle of the cake, like an insertion.
- The rest of the dark chocolate mousse is poured over. Then the entire cake is frozen.
- When ready to decorate, the cake is removed from the freezer and covered with a cocoa mirror glaze. Little walnut meringue baked previously will serve s decorations on the cake.
How to make the perfect meringue layers:
The secret is to bake the meringue cake layers at a low temperature (212F/100C) in the oven for about 90-100 minutes. If the heat is higher, the meringue will burn.
If the heat is too low, it will not set properly. The result has to be a thick, crunchy meringue layer that will add texture to the cake.
After you bake the layers, let them cool in the oven slowly. It works better if you make the meringue layers the night before, as you can leave them in the oven until the next day.
They will dry out, which is what we need.
The meringue is usually very sweet. Therefore dark chocolate works best for this cake as it balances its sweetness.
How to make the meringue layers:
Preheat oven to 212F/100C. Cover the bottom of a baking tray with parchment paper. Draw a 9-inch diameter circle on the parchment paper and also a 7-inch diameter one.
If you do not have enough space, use two baking sheets.
Separate eggs. In a large bowl, pour the egg whites and beat them with an electric mixer on medium-high speed until soft peaks form.
Slowly add sugar, about one tablespoon at a time, until all the sugar has been added. Add the vanilla.
Continue beating until the whites are stiff and glossy. Fold the ground walnuts into the eggs with a spatula.
Fill a 1-quart sealable plastic bag (or pastry bag) with the meringue. Seal the bag almost completely, leaving a small opening for air to escape from the top as you squeeze.
Snip off one corner of the bag with scissors, making a 3/4-inch-wide opening. Fold the top of the bag over a few times, then gently push the meringue down to the snipped corner.
Holding the bag perpendicular to the baking sheet, pipe the meringue inside the 9-inch circle and the 7-inch circle, starting from the middle and working your way out to the edges into a spiral.
Use a spatula to smoothen up the surface of the meringue. Pipe the leftover meringue into 1 1/2-inch-diameter cookie, spacing them about 1/2 inch apart.
Bake everything at 212F/100C for 90 minutes. Shut off the oven and let the meringue dry overnight, preferably.
You are basically done with the most complicated part of this cake, which was not very complicated, correct?
The chocolate mousse is easy to make, so please follow the instructions at the bottom of this post.
Also, you will find the instructions for the final layer of the cake, the one that will give the cake the beautiful shine, the mirror glaze.
These types of cakes are usually glazed and finished while still frozen unless the recipe says something different.
A few tips about the mirror glaze:
This is a glaze that used to be made only in professional kitchens, but in the last few years, people started to make it at home as well, and it suddenly became a trend.
Do not be afraid to make it, but make sure you read the instructions and follow them step by step.
Make sure you cool down the glaze to the right temperature(read the recipe card). You will need a thermometer for this step.
You cannot pour warm glaze over a frozen cake. If the glaze is too cold, it will harden right away because of the gelatin.
If it is too warm, it will melt the surface of the cake, and you will end up with a mess.
