No Bake Orange Mousse Cake

Sharing is caring!

This No Bake Orange Mousse Cake is an easy, light, delicious cake that can be made all year round when you need to make a dessert but you do not want to bake. This is a cake that is built upside down, refrigerated over night and flipped on a cake platter the next day.

There is no need for decorating and there is no baking involved. How awesome is that?

It is also an easy recipe that doesn’t require you to slave in the kitchen for hours. If you move on a normal speed, you should have this cake together and in the fridge in no more than one hour.

This is an old recipe that I had in my pile of recipes for many years now. I made this cake multiple times in the past  for birthdays, New Year’s Eve, summer celebrations and anything else in between. 

The cake is built with ladyfingers that mimic cake layers, a filling that is made of egg yolks, sugar and orange juice cooked on the stove until thick, mixed with gelatin and whipped cream.

The face of the cake is covered in thin slices of orange, that give the cake a beautiful elegant look.

Also, there is no need to decorate the cake, as it will come out of the springform already beautiful.

It is a perfect option for non bakers or during hot summers when you don’t want to heat up the oven, or for any event where you prefer a light, beautiful dessert to impress your guests.

I did some research on this recipe and I could not find many versions out there. It seems to be a Romanian cake that is very popular, but there are not a lot of recipes out there written in English.

The original recipe is made with raw eggs, but I am not a fan of raw eggs in a cake, so I adjusted the ingredients and the way is made.

I think this is a much safer recipe to make,  like the other very popular cake recipe I have on my blog: Charlotte Russe Cake– a classic European cake that is also very easy to make.

How to make this no bake orange mousse cake:

First of all, this is an upside down cake that is built in a springform pan. I used a 9 inch springform pan and lined the bottom and the inside walls with foil.

We use foil so we can unmold the cake easier when is ready to plate.

If you are a professional baker, you probably know already about the clear acetate roll that would help you line the inside walls of a cake pan when you make a mousse cake.

That clear acetate is a life saver, as the cake gets a smooth and elegant finish, when used.(see the tool that I used on the bottom of the recipe or visit my store here)

If you do not have that acetate roll, don’t worry, just use plastic foil to line the cake pan, it should be good enough.

Grab two oranges, wash them well, then grate the peel, because we will need the zest from both of them.

Peel the oranges one by one and remove the white layer as much as possible. Slice the oranges  about 1/4 inch thick.

Grab the springform pan and place the orange slices on the bottom of the pan and around.

No Bake Orange Mousse Cake- layering the cake

Try to choose orange slices that are pretty enough, as that layer will be basically the decoration on top of the cake.

For the next step, start with the gelatine that needs hydration. For 2 1/2 tablespoons you will need more or less 1/2 cup cold water. While the gelatine is hydrating, cook the filling.

You will need to separate the eggs and place the egg yolks in a sauce pan together with the orange juice, salt, sugar and orange zest. (Save the egg whites to make this delicious cake)

Place the sauce pan on medium-low heat and cook, stirring constantly, until the mixture thickens.

It is ready when the mixture is coating the back of a spoon and holds a line when you draw your finger through it.

Remove the mixture from the heat and add the gelatine. Stir well to make sure that the gelatine is incorporated completely into the mixture. Set aside to cool.

In the meantime, whip the heavy cream with an electrical mixer.

HOW To assemble the cake:

Pour half of the filling over the oranges you placed in the springform.

On top of that filling place half of the ladyfingers. The ladyfingers will mimic the “cake” layer.

During the overnight refrigeration, the ladyfingers will soak part of the mousse’s moisture and become softer and delicious.

No Bake Orange Mousse Cake- layering the cake

Try not to leave a lot of space in between the ladyfingers. They expand a little bit while soaking the moisture, but it is nice when you have a cohesive layer of cake in between the layers of mousse.

Repeat the procedure with the other half of the mousse and another layer of ladyfingers, which will become the bottom of the cake when you flip it upside down the next day.

Cover the springform with foil and place it in the refrigerator over night or for at least 4-5 hours. That gelatine needs to set and the ladyfingers need to soak a little bit of the moisture from the mousse.

The next day, or when ready to serve, remove the foil and place the serving plate on top of the springform.

Grab the plate and the springform with both hands and flip them upside down, so the cake ends up on the plate.

Remove the springform and the plastic foil.

Your cake should look like this now:

Isn’t that beautiful?

You will end up with at least 12 slices of cake, but you can definitely cut the cake thinner if you have more guests.

Some people are nervous working with gelatin desserts, but if you follow the instructions, you should end up with a beautiful cake that everyone will love.

This No Bake Orange Mousse Cake is light, fluffy and melts in your mouth. The combination of whipped cream and orange cream is sweet enough to calm down a sweet tooth, without being overwhelming.

I did serve it as it was, but some people add a dollop of whipped cream on each slice. 

CAN I Use some other fruits instead of orange?

Yes, you can. Just replace the amount of orange juice with some other fruit juice. For example, strawberries are good, or CANNED pineapple.

Or, you can still use oranges, but replace regular ones with blood oranges, or make a combination of regular and red oranges for a more dramatic look. 

NOTE: DO NOT USE pineapple, kiwi, papaya, mango in a raw form. These fruits contain bromelain, an enzyme that destroys the gelatine in the mixture.

The cake is not going to set and you will end up with a “soup” cake.

Trust me, it happened to me, at the beginning of my baking career and we ended up eating the cake from soup bowls with spoons. 🙂

The mousse set before I had a chance to pour into my mold. Could it possibly be too much gelatin? I did 2.5 Tablespoons of gelatin.

I am not sure what kind of gelatin you used. It is possible that it was too much or the gelatin was too strong. It never happened to me or to other people I know they make this recipe. Try to lower the amount, maybe use only 2 tablespoons instead of the whole amount.

Amazing recipe, easy to make and not very sweet. A light dessert that I highly recommend! I used 9 gelatin sheets and the consistency came out perfect. It was very easy to flip it upside down after 5 hours in the fridge. The cake looks beautiful, although my orange slices were not perfect. This may become my favorite summer dessert. I'd be curious to try it again soon with strawberries, since it's the peak season here where I live. Can I replace the 1 cup orange juice for 1 cup of crushed strawberries?

I think you can.I would squeeze the strawberries or pass them through a sieve, to remove the seeds. They can be quite unpleasant in the texture of the mousse.Same with raspberries. I am happy you liked the recipe. I like this cake very much too.
