Chocolate and orange mousse cake
Chocolate and Orange Mousse Cake
I made this cake the last time I needed something festive but not overly complicated. I couldn't take pictures of the slice because I gave it as a gift, but I checked the base and the cream beforehand and had no worries. Orange and chocolate pair well together, and the cake doesn't require advanced techniques.
Quick Info
Total time: about 4 hours (including cooling)
Preparation time: 40 minutes
Baking time: 30 minutes
Servings: 10-12 slices
Difficulty: medium
Recipe type: festive cake, suitable for birthdays or special occasions
Ingredients
For the base:
5 eggs
170 g sugar
11 tablespoons flour
3 tablespoons cocoa powder
1/2 cup oil
1/2 cup milk
1 packet baking powder
a pinch of salt
(optional) grated zest of one orange
For the syrup:
juice from 2 oranges (if they are sour, you can add 1 teaspoon of powdered sugar)
For the chocolate mousse:
200 g dark chocolate (minimum 55% cocoa)
200 ml heavy cream (unsweetened)
6 tablespoons sugar
300 ml sweetened liquid cream
For decoration:
whipped cream (2-3 tablespoons)
chocolate flakes
zest from one orange
Preparation Method
1. Prepare the base.
Separate the eggs. Whip the egg whites with a pinch of salt until stiff peaks form. When the foam is firm, add the sugar in 2-3 batches and continue mixing until it dissolves. Gradually incorporate the egg yolks, then add the oil and milk, mixing briefly after each addition. Combine the flour with the cocoa powder and baking powder, then gently fold them into the mixture with a spatula to avoid deflating the foam. If using orange zest, add it here.
2. Bake the base.
Pour the mixture into a round cake pan (26 cm) lined with parchment paper at the bottom. Level it out. Place in a preheated oven at 175°C for about 30 minutes. Do the toothpick test towards the end to ensure it’s baked. Let the base cool completely, then remove it from the pan.
3. Prepare the chocolate mousse.
In a saucepan, heat 200 ml of heavy cream with 6 tablespoons of sugar over low heat until it starts to boil. Turn off the heat and add the broken chocolate pieces. Stir until the chocolate is completely melted. Allow the cream to cool, then refrigerate for about 2 hours.
4. Whip the cream for the mousse.
Take the chocolate cream out of the fridge and whip it until it becomes airy. Separately, whip the 300 ml of sweetened liquid cream until it thickens. Set aside 2-3 tablespoons of this whipped cream for decoration. Gently fold the remaining whipped cream into the chocolate cream, mixing briefly until combined.
5. Assemble the cake.
Cut the completely cooled base into 3 equal discs. Place the first disc on a serving plate, soak it with some of the orange juice, and spread a portion of the mousse. Add the second disc, soak it, and spread more mousse, reserving 4-5 tablespoons for finishing. Place the last disc, soak it as well. Cover the cake with the remaining mousse in a thin layer on the sides and top.
6. Decorate the cake.
Decorate with the reserved whipped cream, chocolate flakes, and grated orange zest. You can also sprinkle chocolate flakes on the sides. Refrigerate the cake for at least 3 hours before serving to allow the mousse to set.
Why I Make This Recipe Often
The cake has a balanced texture, with a fluffy base and a smooth mousse, and the orange flavor elevates it beyond ordinary desserts. It doesn't require complicated decoration and keeps well in the fridge for several days. I love that it can be made with common ingredients.
Tips and Variations
Tips
It's important for the base to be completely cooled when cutting; otherwise, it will crumble or stick to the knife.
The mousse needs to chill to set and not run when spread.
If you have organic oranges, use the zest in the base and for decoration.
Substitutions
You can also use milk chocolate in the mousse, but it will be sweeter and softer.
If you don't have sweetened liquid cream, add sugar to taste when whipping plain cream.
White flour can be replaced with type 650 flour, but the texture may be slightly denser.
Variations
You can add a little orange liqueur to the syrup if it's not for kids.
For the mousse, you can use chocolate with different cocoa content according to preference, but adjust the sugar.
If you want a simpler decoration, just whipped cream and a bit of orange zest are enough.
Serving Ideas
The cake is served cold, straight from the fridge.
It pairs well with coffee or tea, especially for events or small gatherings.
Frequently Asked Questions
1. How do I cut the base without crumbling it?
The base must be completely cold. Use a long, thin-bladed knife and cut with slow movements.
2. Can I use another juice for the syrup?
Yes, but orange juice balances the chocolate flavor very well. Lemon would be too sour, and sweet syrups would overpower the dessert.
3. If I don’t have Meggle cream, what can I use?
Any liquid cream works, as long as it’s somewhat stable when whipped. Adjust the sugar at the end to taste.
4. Can I make the base a day in advance?
Yes, the base can be baked and stored at room temperature, wrapped in plastic wrap.
5. Is it necessary to chill the mousse before assembling?
Yes, the mousse needs to be cold and set; otherwise, it will run when cut.
