Walnut Meringue Cake With Dark Chocolate Mousse
You need to try this recipe at least once in your life time. Decadent, delicious and elegant, this cake fits for real in the “food porn” category.
I was inspired by my favorite Romanian baker Ana Consulea and her recipe , and made this cake for my coworker who celebrated his 40th birthday. It was a real hit!
The cake is not difficult to make but it does require some time.
You will need:
- a 9×3 inch cake ring to build the cake, but if you don’t have one, a 9-inch springform will be OK as well.(23 cm diameter)
What is inside the cake:
- The base of the cake is a 9-inch(23 cm) walnut meringue cake layer
- Over that layer, dark chocolate mousse is poured over.
- On top of the mousse, there is a 7-inch layer walnuts 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 , then decorated with little walnut meringue baked previously.
TIP: I suggest you use a kitchen scale for this recipe and also for any recipe you see online that comes from outside of United States. Having a scale in the kitchen is necessary, especially when you are baking.
With the globalization and the internet, the recipes are coming to us from all over the world, so it is important to be able to correctly measure the ingredients.
One cup of all-purpose flour doesn’t have the same weight as one cup of cake flour, because of the texture, but 200 grams of anything would always be 200 grams.
Few things about the meringue cake:
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 inside 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 the sweetness of it.
How I made 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 2 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 1 tablespoon at a time, until all the sugar has been added. Add the vanilla.
Continue beating until the whites are stiff and glossy. Fold in 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.
Working with 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 cookies, 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 type of cakes are usually glazed and finished while still frozen, unless the recipe says something different.
Few tips about the mirror glaze:
This is a glaze that used to be made only in the professional kitchens, but in the last few years people started to make it at home as well and 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 to make sure you brought the mixture to the right temperature.
You cannot pour warm glaze over a frozen cake. If the glaze is too cold it is going to harden because there is gelatin in it.
If it is too warm it will melt the surface of the cake and you will end up with a mess.
The final cake looked like this. It was divine and if you are brave enough, I challenge you to make it.
It might become one of your favorite things to bake. It is a great recipe to impress, that’s for sure!
